[PHP] Problem with IE 6.0
Hello and thanks in advance,
I have a problem with the cache in Internet Explorer version 6.0
When I put these lines in the page
header ("Expires: Mon, 1 Jan 1997 01:00:00 GMT");
header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header ("Cache-Control: no-cache, must-revalidate");
header ("Pragma: no-cache");
Internet explorer stills make the cache to the page, is there any
solution to these problem and how is it?
Thanks and regards

RE: [PHP] Re: exec() Error
Hi, Shawn and all:
I tried to run the script using the method you suggested for Windows, but it
gives me this:
'http' is not recognized as an internal or external command, operable
program or batch file.
I could telnet and ping to the server using #80 to where the script
calculate.php is located, though. Do you or anyone else on the list might tell
me why I cannot execute the script through this method?
Here is my calculate.php, if it is of any help to you for troubleshooting:
http://www.mysite.com/lung.txt";;
$handle = fopen("lung.txt", "rb");
$contents = stream_get_contents($handle);
fclose($handle);
$count = count(explode(" ", $contents));
echo "There are " . $count. " words in " . $file . "";
?>
Thanks in advance.

Well, whatever OS you use, try typing that at the command line and see
if it works. That's what exec does in effect.
Linux:
$ http://www.mysite.com/calculate.php
Windows:
C:\> http://www.mysite.com/calculate.php

Alice,
exec() is for executing binary commands over an interface that your
operating system inherently understands, such as its own file system. I
seriously doubt either machine in question is equipped to handle URLs
from the command line without invoking a web browser.
As I said before, you should investigate cURL or AJAX to push the info
to your remote script, and then use exec() from the remote machine to
execute the client's program which is, as I understand it, housed on the
remote script's machine.

These are the headers I send when I want to prevent any caching:
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: ".gmdate("D, d M Y H:i:s")."GMT");
header("Cache-Control: no-store, no-cache, must-revalidate, post-check=0,
pre-check=0");
header("Pragma: no-cache");
These work fine for me in all browsers.

[PHP] How to check if $string contains Hebrew characters?
Hi,
I have a $string and i want to know if it contains Hebrew characters in it,
I wrote the following:
> function containHebrewChars ($string)
> {
> $chars = "אבגדהוזחטיכלמנסעפצקרשת"; // ABC of hebrew chars (AlefBet)
> $chars =
> preg_replace("/([\xE0-\xFA])/e","chr(215).chr(ord(\${1})-80)",$chars); //
> convert it to UTF8
> if (preg_match("/[".$chars."]/", $string)) return true;
> return false;
> }
>
I'm pretty sure there is a better way to do this (regex is overkill), any
ideas?
Regards,
Nitsan
RE: [PHP] How to check if $string contains Hebrew characters?
If your goal is to eventually convert Hebrew chars to something else, you could
just use str_replace or stri_replace and have each Hebrew char as an array
element, replaced by another array element as a match.
Example in English:
str_replace(array('a','b','c'),array('t','u','v'),$string);
This will replace all instances of a,b and c with t, u, and v respectively.
This removes the regex resource.

RE: [PHP] How to check if $string contains Hebrew characters?
The strtr will be better as he's not looking to actually replace the
characters.
Looping through each character and running strtr will work, but you should run
a timer on both the regex and strstr. See which is faster.

Well, "http://www.mysite.com/calculate.php"; is not an executable. Try
this instead:
exec("php /calculate.php");

I just found out that using cURL in my script allows me to call script from
machine to machine. It turned out perfectly. Thanks to all who have been

Umm...
Is $missingLabels supposed to be what you're var_dump()ing later in the
code? Cuz you call it $labelsFaltantes almost immediately after, which
has not been defined (by what I can see).

Re: [PHP] array_diff()?
Actually that was a miss when I was "translating" var names.
Here follows the code again, untouched this time:
File _pt has ~2300 lines while file _es has ~1700. Not a chance of them
having the same labels :)

I still don't think this is how exec() should be used when executing remote PHP
scripts via HTTP, since the web server is not going to give you the underlying
code simply because you're calling the URL from PHP and not your web browser.
User-Agent tags do not a secure connection make.
Perhaps doing a wget and directing it to /dev/null (if you're on *nix) would be
appropriate to invoke a remote script and pass it parameters. Hell, even wget
to standard output if you want, and use that as your "result code." It's
basically doing what cURL does, but outside of the PHP script itself.
Anyway, I digress. My point is that exec("php http://mysite.com/script.php";)
will fail, since it will be reading the remote script's OUTPUT, and not the
remote script's SOURCE CODE.

I dont' know how come his code works either. I figured that exec() is not
going to get me anywhere when I have it stored remotely.
I am now using cURL instead of using exec(), since it is doing a lot closer
to what I initiated. I am not sure if I should have a new thread for this, but
I found that things start to get a little weird when I tried to do cURL with
Perl files inside. The PHP only brings me back Perl code and not the processed
content. Is this something I should not be doing with cURL? It seems to do
quite a bit of powerful processing when I wrote everything in PHP and have it
stored remotely.

Alice,
If it's returning the code instead of the processed content, then it
means that the webserver which houses the Perl script is not
executing/parsing it. You should check with the administrator of the
remote webserver to see if they have a Perl module installed, and if it
is configured properly for your web app.

[PHP] prepared statement
Hi all: We are use PHP PDO's Prepared statement to send SQL query to Mysql server. According to PHP PDO doc, Prepared statement are fast for executing multiple SQL queries with same parameters. "by using prepared statement you avoid repeating the analyze/compile/optimize cycle" Our application is a web application, each request will have a new Prepared statement handler generated by PDO Lib. so prepared statement actually slower than non-prepared statement. I just want to know how can we cache Prepared statement handler, So we can re use it in later http request. for example: we have a query to pull out all product information from mysql db, each query just has a different product id , all other parts are same. -- View this message in context: http://www.nabble.com/prepared-statement-tp18123270p18123270.html Sent from the PHP - General mailing list archive at Nabble.com. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The query is the same.
It works out to be:
select * from products where id='X';
So you can just do something like this:
$product_query = $dbh->prepare('SELECT * from products where id=?');
$ids = array(1,2,3,4,5);
foreach ($ids as $product_id) {
$product_query->execute(array($product_id));
$product_details = $product_query->FetchAll();
print_r($product_details);
}

On Wednesday 25 June 2008 8:24:06 pm ctx2002 wrote: > so only benefit for use prepared statement in Web environment is to prevent > SQL > injection? > > regards It's somewhat more complicated than that. (The following is based on my own experiences with PDO and a conversation with PDO's original author, Wez Furlong.) A normal query is taken as a single string, parsed, executed, and returned. End of story. A prepared statement is taken as a template string, parsed, and cached. It then has variables passed into it, almost like a function call. Caching the query once tends to cost a little bit more than just executing it straight. The savings come in later calls, when you skip the compilation step. You save per repeated query the amount of the compilation. As Chris said, you can't save compiled queries between requests. However, they can still be a performance benefit in certain circumstances. With MySQL in particular, those circumstances are weird. First of all, MySQL's query compiler is actually pretty damned fast to start with, especially with the fairly simple queries that tend to predominate in web applications. So if you save the cost of a repeated compilation but the compilation itself is already cheap, you won't really notice much improvement. Databases with slower compile engines (eg, Oracle) or queries that are considerably more complex (lots of joins that the compiler has to figure out how to optimally order, for instance) will see more of a benefit. You'll also, of course, see more benefit on queries that are run many many many times, but for anything but insert queries if you're smart you're already designing your app to avoid repeating the same query anyway. :-) Secondly, MySQL's native prepared statement support is somewhat braindead, as it bypasses the query cache entirely. So you can have prepared statements or the query cache, but not both. For that reason, you may get better performance by using PDO's emulated prepared statements instead. (Check the manual for how to enable that.) That way PDO will do the prepared statement work and MySQL will still use the query cache. Experiment to see if this helps in your case. Also remember that PDO itself adds some overhead with its database abstraction. It's far less than doing the same abstraction in userspace, but it is there. A straight PDO-based query will not be as fast as, say, the same query run directly through ext/mysqli. However, PDO does give you all of the nice things PDO gives you. :-) In my testing while working to port Drupal from ext/mysql[i] to PDO, I have found that by removing all of our userspace prepared statement code and using PDO instead, we're getting about a wash on performance. We're OK with that, however, due to the increased security and flexibility that PDO offers. So the answer is that PDO is not going to get you a big performance boost on MySQL in a typical web app, but you can probably break even on performance overall while adding flexibility, additional features, and a nice API. -- Larry Garfield [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

That's not what Alice asked for though. She did mention that a remote
call would be made somewhere, but her question was:

And that works just fine using exec().
