[PHP] Structured Code vs. Performance
I got different portions of code only used for certain purposes (who don't
;-)?). But what, in your opinion (better: in your experience) would be the
best regarding script-performance: Putting each code-portion in a separate
file and include it if required, putting it in a constant-dependent
if-structure (if (defined('FOO') && FOO) {class foo{}; function foo(); ...})
or simply let it be parsed every time?
My first choice is using separate files, but if a file e.g. only contains 20
lines, I fear it would take much longer to include the file against simply
parsing these lines in the existing file. And as parsing is done really
fast, there might be no real performance-loss in case of not using the
mentioned code. With the constant-dependent if-structure I don't know if
there are any performance-benefits if FOO isn't defined or defined as FALSE.
Looks for me a bit like a philosophical question, but maybe you have
something to say about it nevertheless. A good thing for me would be
something like: up to 125 lines of code you get an adequate performance with
simply parsing it every time, with more than 125 lines you would get a
better performance with using separate files - just kidding, surely the
number of lines in this case is 42 ;-).
Looking forward to your answers

Install a compile cache like eaccelerator or APC. keep your code
organized, that usually means use multiple files for the code.

To my understanding (and anyone who thinks differently can correct me) there
is very little performance loss in including (or requiring) multiple files,
unless the number of files reaches something like over a hundred. This says
nothing about the amount of code in those file of course. But like you said,
parsing is fast.
I personally prefer the approuch:
1 directory = package
1 subdirectory = subpackage
1 .php file = class
I haven't noticed that much performance degradation in my scripts, while
have amounts several dozen of files.
You can avoid duplication by only using require_once or include_once. PHP
automatically does the checking that the file is not included if it has
already been included once. The Zend framework works this way for instance.
Just simply require_once, at the beginning of the file, everything the file
in question needs.
Constants on the global scope are a bit of a different case. But if you do a
lot of objects, you can instead of the global scope put all of your
constants into classes, which works just as well. This avoids name
conflicts.
Hope that answered your question.

Make your code readable and manageable first, then worry about the rest.
I always go for multiple files because it means the project is much more
manageable.
My first choice is using separate files, but if a file e.g. only contains 20
lines, I fear it would take much longer to include the file against simply
parsing these lines in the existing file.
Put your "misc" functions in one file and include it when you need it.

defining functions or classes conditionally is not recommended, because it
means they can only be defined at runtime and not compile time ... which will
kill any op-code caching you might have in place or use in future (e.g.
php.net/apc)

for a few 1000 lines of code the difference is probably not measurable in any
meaningful way (a spam assassin deamon, or something similar, hogging the CPU
will probably have more realworld effect on the speed of your script).
when your app becomes very large you will probably benefit from only including
little used code when it is actually required.
there is also the issue of maintainability - having to check and keep track of
include/require statements scattered all through the code, and working through
'undefined class/function' errors when enhancing/bugfixing/refactoring code
maybe
alot more hassle than using a single global 'init' script that includes pretty
much
everything bit of code your scripts might need.
personally I tend to go for maintainability over performance if the choice is
mutually exclusive - generally your time is alot more costly than the purchase
and placement of extra RAM, faster CPU, faster disks, etc.

PHP indeed require_once() and include_once() help with maintainability but it should be mentioned that if you are going to use an op-code cache (as Rob Cummings mentioned also) then it is highly recommended that you stick to using require() and include() as, IIRC, op-code caches handle your includes much faster when they are 'unconditional' (probably not the correct word in this context but what I mean is that there is no check to see if the file has been previously included) also using an absolute path in your include statements helps php (and the op-code cache if you use it) it go a little faster because there is no need to work through the directories defined in the include_path ini setting to find the file. > automatically does the checking that the file is not included if it has > already been included once.

I'm not completely sure, but I think you're wrong there. Removing the
condition in the example above will not affect any opcode caching since
PHP cannot determine the result of that conditional until runtime.
To the OP: You're treading on the dangerous ground of premature
optimisation. In the grand scheme of things the time taken for PHP to
compile your scripts is tiny compared to the time it will take to run
it. And as mentioned there are several ways to cache the compilation
output which turns that tiny time into a negligible time.
Worry about the structure and maintainability of your app rather than
thinking about how fast it is. Once you have the app doing something
useful you can start to think about how to make it do it quickly.

one of us is reading the other's post incorrectly - I have a feeling we are
both trying to say the same thing.
namely runtime class definitions don't have the same benefit of op-code caching
as compiletime definitions.
or not?

Not ;). There is no such thing as a compile-time definition in PHP.
Whether there is conditional definition or not, the opcode cache will
look the same. The reason for this is that function and class
definitions happen at runtime not compile time. This would have to be
the case for conditional definition to work at all, since the compiler
cannot determine the value of a condition at compile-time.

okay, but I was just paraphrasing the man Rasmus, although I admit I may
have misinterpreted (or misundersstood the 'why') - thought I pretty sure
he has written on a number of occasions that code like the following sucks
for op-code caches and should be avoided:

[PHP] Re: Structured Code vs. Performance
Thank you for the answers. My abstract: Use separate files for separate code. Easy to maintain, no real loss in performance. That's fine, as I'm just doing so (like if I need a database abstraction, I include dbas.php and if dbas.php needs some miscellaneous functionality, it includes misc.php by itself - so no worry for me to think about the dependencies of the scripts). Yes, that makes use of require_once() et al., but as I didn't plan to use something like ACP, it seems to be no problem so far. Use absolute pathnames when including. That's too what I do, as I don't want scripts to be found accidentally - see the thread about inlcuding config.php for that ;-). Caching code might be another possibility for gaining speed - I will think about that later, thank you for the hints. And last but not least: First make your code work in a proper and maintainable way. Then think (and ask) for speed. And don't expect people to assume you have done it this way ;-). If someone wants to complete this abstract, it would be appreciated, otherwise I'm done. Thank you again!

[PHP] Functions with Static Variables vs. Classes
For some simple applications I use a function to collect values in a static
variable and to return them when called in a special way, just like this
(fairly senseless) example:
function example($elem='') {
static $store = array();
if (!func_num_args()) return($store);
... do something with $elem ...
$store[] = $elem;
}
I would call this a singleton-micro-class, as it works like a class with
data and methods, but there is always only one of it, having only one
method.
Why do I? Because I dont need to worry about variablescope as if I would use
global variables and I dont have to initialize an object before the first
call (with the scope-problem again). I simply can call it everywhere and
everytime.
Do you have any comments to this approach?

As I have always understood it, the heavyness only really comes in when
there are conditional includes or requires
if (foo()) {
require_once('foo_class_inc.php');
}
else {

[PHP] Variable Names
Hi,
I seem to be having a problem in assigning a value to an array where the
array is called dynamically.
e.g. the physical name for the array is "my_array", so:
my_array[1] = "test";
works fine.

Hi,
I seem to be having a problem in assigning a value to an array where the
array is called dynamically.
e.g. the physical name for the array is "my_array", so:
my_array[1] = "test";
works fine.
$array_name = "my_array";
$array_name[1] = "test";
does not work.
I have tried $$array_name[1] = "test"; but to no avail.
Here is my code
/**

function add_form_to_session() {
foreach ($_POST AS $key => $value) {
if (is_array($value)) {
foreach ($value AS $subkey => $subvalue) {

else {
$_SESSION['ses-app-form']->$key = $value;
//echo "value: ".$key." = ".$value."";

[PHP] Re: Variable Names
The manual says:
In order to use variable variables with arrays, you have to resolve an
ambiguity problem. That is, if you write $$a[1] then the parser needs to
know if you meant to use $a[1] as a variable, or if you wanted $$a as the
variable and then the [1] index from that variable. The syntax for resolving
this ambiguity is: ${$a[1]} for the first case and ${$a}[1] for the second.
Does this help you?

AFAIK the above line should cause an error on the second run of the

Pass. Looking back it looks like it happened one of the times I replied.
Didn't do it on purpose, honest! ;)
Whether there is conditional definition or not, the opcode cache will
look the same. The reason for this is that function and class
definitions happen at runtime not compile time. This would have to be
the case for conditional definition to work at all, since the compiler
cannot determine the value of a condition at compile-time.
okay, but I was just paraphrasing the man Rasmus, although I admit I may
have misinterpreted (or misundersstood the 'why') - thought I pretty sure
he has written on a number of occasions that code like the following
sucks
for op-code caches and should be avoided:
if (foo()) {
class Foo { }
}
Hopefully he's reading and will be able to give us a definitive answer.
here is the post that I was recalling:
http://lists.nyphp.org/pipermail/talk/2006-March/017676.html
I believe his third point validates what I was saying although I did
make a bit of a mess with regard of my use of terminology.
Hmm, Rasmus seems to be saying that opcode caches have a way to optimise
the definition of entities, and by defining them conditionally they
can't make use of that. That kinda makes sense, but I'd expect the
difference to be negligible unless you're talking about a file with
thousands upon thousands of definitions.
Anyhoo, back to the coalface.

I think so - otherwise static Variables would be quite senseless. The line
starting with static is (so do I think) once evaluated at compile-time or at
the first run and the ignored.

I believe it's a compile time definition ... which is the reason you can only
initialize static vars with scalar values (and not the result of expressions or

[PHP] One more data formatting question
Hi all: I'm trying to parse out some HTML code back into "regular" string values and I keep getting tripped up by the non-breaking space value ( ). I see that html_decode_entities() can be used to convert this back to a viewable space, but the documentation tells me that the space value it uses is not the same as a TRIMable space (i.e., ASCII 32). Is there a quick, fast, and easily implemented way to convert any non-breaking space found in a string back to the ASCII 32 space value? I suspect that one of those amazing POSIX expressions could do it, but I'm having trouble wrapping my head around them at this early hour. Any help you all can provide will be extremely appreciated!

Re: [PHP] problem with url_fopen on free hosting environment
Ok, I did find a solution by accident.
I just blocked all tcp requests on port 80 and 443 comming from my own
outside IP. Since I have a couple of servers, I just dropped the
following into rc.local on all of them:
# Blocking url_fopen requests
ownip=`curl -s http://checkip.dyndns.org | awk '{print $6}' | awk '
BEGIN { FS = "<" } { print $1 } '`
iptables -A INPUT -s $ownip -p tcp --dport 80 -j DROP
iptables -A INPUT -s $ownip -p tcp --dport 443 -j DROP
Maybe this helps somebody :)

Thanks for the infos.
I read through the very interesting post, but I did not find it to be
a solution for my problem.
I tried to limit connections with iptables, but it did not work out.
I'm not an expert at this, I tried like it is described here:
http://www.linux-noob.com/forums/index.php?showtopic=1829
I know it just limits new connections, and I thought this would work
out, but it didn't. Should I try to limit all connections?
Also it makes me wonder why mod_evasive for apache does not block this.
I will probably try to come up with a solution by using mod_security.
But it would be much nicer if it would work on the iptables level.

Hi Samuel,
I found this forum topic the other day http://uclue.com/?xq=874, and
I thought it's pretty nice as a start/overview. There's also
mod_bandwidth for Apache, not included in the aforementioned topic.
We are not currently having an issue with bandwidth and/or bots
causing overload in the domains hosted with us, so I can't speak
>from our experience with those apache modules. All of our hosting
clients are known by us, and are not constantly changing (as it would
be the case in a free hosting environment). So, these kind of issues
are rare for us, easily identifiable, and from external sources.
None of our clients will try to bypass open_base_dir, or safe_mode,
or allow_url_fopen.
If all of these apache modules are not doing their job and apache is
still overworked... then either they need a tune up in their
configuration or there must be something else behind the scenes and
you'd better off checking your firewall ruleset or a kernel
vulnerability. Probably you'll need to tackle the problem yet one
layer down (firewall), but I'd say first exhaust all choices in the
layer you are working on right now.
Also.. don't forget about mod_security and the like. You could try a
filter on headers. First, do a unit test and check what HTTP_REFERER,
HTTP_USER_AGENT, REMOTE_ADDR, etc look like for a self-calling
script. So, if, say, the user agent is "X" and the local IP
address is the same as the remote ip address then you invalidate the
request for that particular domain.
Ok... hope you get to the solution, and then let us know on the
mailing list

im curious to know where you discovered
php://memory
was a valid stream; i looked through the online manual and found no
reference to it.
nor did i find anything from google. i did encounter it in the php source,
but with no
useful documentation.
a reference of all the streams that are valid with the php:// scheme would
be helpful.
getting to your problem, i think this could perhaps be a bug.
you might file a bug report and post your code along with it; unless
somebody has a
better idea ;)

That's bad because the compiler will *still* parse and compile class Foo(),
but give it some ridiculous internal name so that it's inaccessible. It will
then, at runtime, conditionally give it a real name so that it then becomes
accessible. You'll still have the same cost to parse and compile class Foo()
either way. There is no savings in either compile time or memory use.
if (foo()) {
include('foo.php');
}
This will make baby opcode cache cry, from what I understand, but will not
balloon the memory usage the way the former code will. In practice, though,
a modular, pluggable system (most of what I use) is going to end up having
conditional includes no matter what you do so I generally don't pay much
attention to that type of optimization, since it's irrelevant to me anyway.

This reference to php:// streams you can find on

solution I think I'll report it as a bug tomorrow.

Bleh, just read your comments and then read the comment I quoted and I
find myself needing a morning wakeup slap :) Your comment at the top
says compile-time, not run-time. I'm going to go find a big rock *hehe*.

Hell, I'm all ok with this method... but does (different) webhotells take into
account the amount used with cache/temp files.
If so, some check should be used, and if not. Cache it all!, and remove the
timelimit, some check for the change of image of course, but that all depends
if you acctually change images from time to time..

There certainly is...

Now, I'm not necessarily advocating this style of compatibility
programming, but I remember seeing something like it in PEAR. I think it
might have been the pear SOAP classes where the classes had to be
declared dynamically.
That's a runtime definition. It has to be. The function_exists function
*cannot* be "run" at compile-time to see what the result is, so it must
happen at runtime.
I think maybe the confusion is over terminology. In my mind Zend Studio
would not let me step through a compile-time process, but it's looking
likely that that's precisely what it's doing if I'm to believe
everything I'm reading.
Here's what I see when a file is included... I can step through each
function definition line (function ...), and at the same time it
executes any inline code outside of the functions. That seems like a
runtime process to me. If there is a function definition contained
within the file, or a function defined within a function, the debugger
does not hit that definition unless the condition matches or the
function is called.
To me this indicates that PHP defines entities at run time. It's
possible that it also defines them at compile-time, but I don't know the
internals well enough to know.

[PHP] Glob
Please can someone help me understand the following:
I have 4 images with a .jpg extension in a folder.
The following reads all four:
$files = glob("thumbs/{*.gif,*.jpg,}",GLOB_BRACE);
All good, however, I noticed that if the extension is in capital
letters, eg .JPG it doesn't work. Apparently this is because when
using *. in glob it's case-sensitive (I have RTFM/STFW)
So, I would expect the following to work, but it's reading each image twice!
$files = glob("thumbs/{*.gif,*.jpg,*.jpeg,*,png}",GLOB_BRACE);
What am I missing?

You have *,png when you should have *.png. The * is matching everything.

It's private in the context of runtime requests to retrieve or set the
value via the normal methods for setting and retrieving data properties.
Most people use print_r() and var_dump() to debug their data structures,
in which case they certainly do want to see the private members. Even if
they were hidden you would find it to be absolutely necessary that they
be exposed when serialized, otherwise how could you properly
unserialize. Given that condition, does it matter that they are visible
via print_r() or var_dump() when another method for viewing them exists?
Cheers,
Rob.

[PHP] WSDL Question
For the lasts day I have been fighting with PHP, and WSDL calls to a thrid
party provider.
Here is what the call needs to look like:
root
IperiaTestOrg
false
SUBSCRIBER_DEFINED_TRANSFER_NUMBER
6179672983
TIMEZONE
US/CENTRAL
I can generate most of the code in fact I can generate all of it but the
Double service setting.
Here is my relevant PHP code.
$SDT = $portal->get_post('SDT');
$SDT = new SoapVar(array('ns1:type' => 'SUBSCRIBER_DEFINED_TRANSFER_ON',
'ns1:value' => $SDT), SOAP_ENC_OBJECT);
$setting_info = array(array('ns1:serviceSetting' => $SDT));
// Getting Iperia Soap Object ...
$soap_iperia = $portal->load_special_object('soap_iperia');
$find_account_obj->accountIdentifier = new SoapVar(array('ns1:account' =>
'root'), SOAP_ENC_OBJECT);
$find_account_obj->orgID = new SoapVar('IperiaTestOrg', XSD_STRING);
$find_account_obj->suspended = new SoapVar(0, XSD_BOOLEAN);
$find_account_obj->serviceSettingCollection = new SoapVar($setting_info,
SOAP_ENC_OBJECT);
$results = $soap_iperia->modifyOrganization($find_account_obj);
That generates the following xml.
root
IperiaTestOrg
false
SUBSCRIBER_DEFINED_TRANSFER_NUMBER
6179672983
The question I have is how do I add in the extra:
TIMEZONE
US/CENTRAL
I have tried a couple ways with no success ...
Any tips would be greatly appreciated.

All safe_mode does is check the UID/GID of the script to make sure it matches that of the target file you're attempting to open. Socket connections don't count. In the next few years, it won't make a difference, since safe_mode has been removed as of PHP 6.0.0.

special characters that way?
$need_message = $_POST['need_message'];

[PHP] Batch process PDF files -- reduce color depth and resolution
Hello, Does anyone know of a good PDF library that works well with PHP (or even not) that can process multi-page PDF files (I am talking thousands) and reduce their color depth from color to black and white as well as reduce the resolution. I'd like it to run well on Linux. Thanks Dan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Calling parent function with call_user_func_array
I'm a self-confessed PHP newb (first step towards a cure, right?), so
apologies in advance for what may be a basic question. I spent an hour
searching for an answer to this and couldn't find one.
I found one post that said there was a problem with this in 5.0.3, but
it didn't indicate whether the fix was also applied to the PHP4 branch.
I'm using PHP v4.4.7. I have class B which extends class A. I'm
overriding a function that is normally called with a variable number of
parameters via call_user_func_array. How do I call the class A
implementation of the function using call_user_func_array from the class
B implementation?
class A {
function doSomething($elements, $level) {
...
}
}
Class B extends A {
function doSomething($elements, $level) {
...
call_user_func_array(/*class A implementation of doSomething*/,
args);
}
}
Thanks in advance for any help!

does this work:?
call_user_func_array(array(parent,'doSomething'),$args);
it's an educated guess, no garantees.

Thanks for taking the time to reply.
I'm working on a Wordpress theme and extending one of their existing
classes (the Walker class if you're familiar with WP). Since WP still
supports PHP4, my theme needs to as well.

Hi gang: I found why the JOIN didn't work for me in this instance, which was I needed to create a third table and JOIN what I needed in that table from the other two. My problem was that I was trying to alter one of the tables in the JOIN. While that might be possible it didn't appear so in my current problem. Thanks for letting me bounce ideas off you peoples.

It doesn't work with PHP 4. I was going to try PHP5 on my
development machine but I will need to do some configuration editing
first.
Here's the exact code I tried:

Re: [PHP] Dynamic Display of Images Stored in DB
Hell, I'm all ok with this method... but does (different) webhotells take into account the amount used with cache/temp files. If so, some check should be used, and if not. Cache it all!, and remove the timelimit, some check for the change of image of course, but that all depends if you acctually change images from time to time.. If it's under your user account then there's no way for them to know which parts of your website are cache/temp folders and which aren't.

wow; i was just looking at the wordpress source; not the prettiest code ive
ever seen..
anyway; in what context do you intend to use the subclass? why dont you
just create a
proxy instead?
eg. (php4)
class WalkerProxy {
var $walkerInstance = null;
/**
* constructor
* accept an existing walker instance or create one from scratch
*/
function WalkerProxy($existingWalker=null) {
if(!is_null($existingWalker) && is_a($existingWalker, 'Walker') {
$this->walkerInstance = $existingWalker;
} else {
$this->walkerInstance = new Walker();
}
}
/**
* walk
*do custom WalkerProxy stuff then invoke the underlying Walker's
walk() method
*/
function walk($elements, $to_depth) {
do something custom here
return $this->walkerInstance($elements, $to_depth);
}

RE: [PHP] WSDL Question
I build an array of the list. Then nuSOAP helps when converting it to XML
but PHP5 can probably do the same thing.
The following builds an array of line_items to put on an order. Then
inserts that array into another array containing more order data:
for ($i = 1; $i <= $num_items; $i++) {
$new_order_item_list[$i] = array(
'line_number' => $_POST[$myline],
'item_name' => $_POST[$myprod],
'item_id' => $line_item[0]
);
}
$new_order = array(
'customer_number' => addslashes($_POST['customer_number']),
'customer_password' => addslashes($_POST['customer_password']),
'customer_email'=> addslashes($_POST['customer_email']),
'send_me_email' => 'yes',
'po_number' => addslashes(trim($_POST['po_number'])),
'itemlist' => $new_order_item_list
}
This is part of the WSDL it is a client to:

Subject: [PHP] WSDL Question
For the lasts day I have been fighting with PHP, and WSDL calls to a thrid
party provider.
Here is what the call needs to look like:
root
IperiaTestOrg
false
SUBSCRIBER_DEFINED_TRANSFER_NUMBER
6179672983
TIMEZONE
US/CENTRAL
I can generate most of the code in fact I can generate all of it but the
Double service setting.
Here is my relevant PHP code.
$SDT = $portal->get_post('SDT');
$SDT = new SoapVar(array('ns1:type' => 'SUBSCRIBER_DEFINED_TRANSFER_ON',
'ns1:value' => $SDT), SOAP_ENC_OBJECT);
$setting_info = array(array('ns1:serviceSetting' => $SDT));
// Getting Iperia Soap Object ...
$soap_iperia = $portal->load_special_object('soap_iperia');
$find_account_obj->accountIdentifier = new SoapVar(array('ns1:account' =>
'root'), SOAP_ENC_OBJECT);
$find_account_obj->orgID = new SoapVar('IperiaTestOrg', XSD_STRING);
$find_account_obj->suspended = new SoapVar(0, XSD_BOOLEAN);
$find_account_obj->serviceSettingCollection = new SoapVar($setting_info,
SOAP_ENC_OBJECT);
$results = $soap_iperia->modifyOrganization($find_account_obj);
That generates the following xml.

IperiaTestOrg
false
SUBSCRIBER_DEFINED_TRANSFER_NUMBER

The question I have is how do I add in the extra:

I have tried a couple ways with no success ...
Any tips would be greatly appreciated.

[PHP] Rewind foreach loop
Hi all,
Is it possible to rewind a foreach loop? eg:
$numbers = array(0,1,2,3,4,5,6,7,8,9,10);
foreach ($numbers as $index => $value)
{
if ($value == 5)
{
prev($numbers);
}
echo "Value: $value" . PHP_EOL;
}
The above doesn't seem to work. In one of my scenarios, when I encounter and
error in a foreach loop, I need the ability to rewind the array pointer by
one. How can I achieve this?
regards,
Jeffery

echo $numbers[$index-1] . PHP_EOL;
That will only give me the value of the previous index. What I want is to
rewind the array pointer and continue with the loop.
I would think that if you rewound the array pointer as above, you'd
simply end up in an infinite loop, as you'd keep hitting the
condition that triggered the rewind. So I'm assuming you have some
other test in there and this is just a stripped down example.
If you're using a one-dimensional array, as opposed to a
multidimensional and/or associative array, you can do (untested):
$Count = count($numbers);
for ($i=0; $i<$Count; $i++) {
$value = $numbers[$i];
if ($value == 5 && some_other_test()) {
$value = $numbers[--$i];
}
echo "Value: $value" . PHP_EOL;
}
Wouldn't be much more complex to extend to a multidimensional array
with an integer index. If you were using an associative array with a
string index, you'd probably have to do something like
$NotJustNumbers = array('a'=>'slurm', 'b'=>'fry', 'c'=>'leela');
$Keys = array_keys($NotJustNumbers);
$Count = count($Keys);
for ($i=0; $i<$Count; $i++) {
$value = $NotJustNumbers[$Keys[$i]];
if ($value == 5 && some_other_test()) {
$value = $NotJustNumbers[$Keys[--$i]];
}
echo "Value: $value" . PHP_EOL;
}

That will only give me the value of the previous index. What I want is to
rewind the array pointer and continue with the loop.

Hi all,
Is it possible to rewind a foreach loop? eg:
$numbers = array(0,1,2,3,4,5,6,7,8,9,10);
foreach ($numbers as $index => $value)
{
if ($value == 5)
{
prev($numbers);
}
echo "Value: $value" . PHP_EOL;
}
The above doesn't seem to work. In one of my scenarios, when I encounter
and error in a foreach loop, I need the ability to rewind the array
pointer by one. How can I achieve this?
echo $numbers[$index-1] . PHP_EOL;
That will only give me the value of the previous index. What I want is to
rewind the array pointer and continue with the loop.
and you're going to be in an endless loop then.. because each time it
gets rewound, it gets the same key again and rewinds and ...
You could do it with a for or while loop probably.
What are you trying to achieve? Maybe there's an alternative.

No, I am only rewinding if there is an error. Then I have the script
auto-learning from the error, fix a config file and then want to go back to
the array pointer to re-execute the process.

Thats what I am looking at now.

As mentioned above.

I'm sorry, allow me to rephrase... in the past 5 months you've made 2 on-topic useful posts, with the rest either being on-topic for an off-topic thread, or completely off-topic. I see no point in saying more, I've made my point. Cheers, Rob. -- ...
