[PHP] Concatenation vs. Interpolation
Hi, FASTER CODE! This question involves Coding Style, Readability, Write-ability and Performance. Some people use the . operator to concat an string to a variable, some people use interpolation (embeding variable into string). = 1st Method (Concatenation) $str = 'My name is ' . $name; 2nd Method (Interpolation) $str = "My name is $name"; = I know that the 1st Method is much faster, according to some benchmarks, which one of them is available in the book "Advanced PHP Programming, page 470". Could we consider the 1st Method as a "Best Practice", which offers better Performance? I know that the performance here is not very much, but is it considerable in a high-traffic website? Thank you in advanced for sharing your opinions, Behzad
[PHP] reading a word document
Hello, Would anyone know or could point me to a link which might have a way for php to read a word document? The code will run on linux, so unfortunately cannot use COM. I've done research on a third application tool which converts docs to html, but have yet to find one which keeps proper formatting and doesn't need root to install it. Would appreicate any help. Thanks!! Tom

[PHP] Switch To VoIPTelco And Save!
Hi, I want to introduce you to a new phone service that I'm using. It's called VoIPTelCo and it transforms your high speed Internet connection into a regular phone line. It works just like your current telephone service except it's 40% - 60% cheaper. You get features like Call Waiting, Caller ID Display, Voicemail, 3-Way calling, Call Forwarding and many more for a fraction of what you're paying now. You can even keep your existing number if you decide to switch to their service. With VoIPTelCo, I also save money on long distance calling. Unlike a regular phone line, VoIPTelCo is "portable", which means I can get phone service anywhere in the world. All I need is high speed Internet access. For example, I use my VoIPTelCo service when I travel and there are no long distance fees because these calls are considered "local". I save so much money just on this alone. Right now, VoIPTelCo is offering a ONE MONTH FREE trial period to friends and families of their customers. There is no obligation and it is completely free. If you'd like to try them out, just click on the link below and you will receive a 30 days trial period, free of charge: http://www.voiptelco.net Hope you'll find this useful.
Re: [PHP] php.ini of PHP 5.2.3
I've discovered that when i type "php -m", openssl is already loaded as module. It seems that PHP 5.2.3 was compiled with "--with-openssl" command. So, why modules with which ones PHP has been compiled do not appear in the phpinfo() report ? thanks a lot, Al.

Re: [PHP] magic quotes
I added the code to my script and I still ended up escaped quotes.
if(ini_get('magic_quotes_gpc')) $_POST['data'] =
stripslashes($_POST['data']); Didn't work at all. I think I read something
about it not working on runtime data. Like gpc if this is correct do you
have another solution? I put this line in the .htaccess file it didn't work
either: php_flag magic_quotes_gpc off... Is there anyway possible? I don't
need it now but it'd be nice to know for the future dev.

Code readability is quite important when working with a team on a
project, and if you got for method 1 on things like this:
$str = '';
It gets quite inreadable, having a double qoute next to a single quote.
while this looks much better:
$str = "";
I just did some benchmarks myself, and you can see that concatenation
is definitly a little bit fast, but it's only 2 seconds on 10 million
loops:
For 10,000,000 loops:
Concatenation single quote:5.62786102295
Concatenation double quote:5.6335657
Interpolation:7.32201290131
Test code used:
';
}
$time[2] = microtime(TRUE);
$x = 0;
$str = '';
$add = '?';
$time[3] = microtime(TRUE);
for($x = 0; $x < 1000; $x++) {
$str = "";
}
$time[4] = microtime(TRUE);
$x = 0;
$str = '';
$add = 'def';
$time[5] = microtime(TRUE);
for($x = 0; $x < 1000; $x++) {
$str = "";
}
$time[6] = microtime(TRUE);
echo 'For 10,000,000 loops:';
echo 'Concatenation single quote:'.($time[2]-$time[1]);
echo 'Concatenation double quote:'.($time[4]-$time[3]);
echo 'Interpolation:'.($time[6]-$time[5]);

I think you're little bit confused by the quotes :P
and since you don't have error reporting including E_NOTICE, you don't
see that there's some problem with your code :P
If I execute your code with the -n option, I get same results.
When I put them in a PHP file like this:
I get :
bool(false)
bool(false)
and you probably also ;)

After the user logs in, the user is returned back to the "buy" page. Now, in this exchange what's the easiest way to maintain the $_POST data?

Re: [PHP] Concatenation vs. Interpolation
You're right. There is a low benefit in performance. But I think it's
valuable
in high-traffic websites. Of course, we should consider a lot of thing to
have a better performance, but Concatenation, IMO, is the best practice.
Let me explain:
َActually, the programmers' preference on readability and write-ability
varies.
I think that concatenation provides a more readable syntax, since it
allows us to distinguish variables from plain strings very easily.
Consider the following code:
$str = 'My name is ' . $name . ' and I live in ' . $city;
VS.
$str = "My name is $name and I live in $city";
(You may view the above code in an Editor with syntax-highlighting
capability for a better result). However, it is possible to offer
opposite examples.
In addition to the Performance on Speed, Concatenation uses less memory
than Interpolation, as explained in PHP Manual. Take a look at the
following URL:
http://us2.php.net/manual/en/language.types.string.php
Quote:
Note: Parsing variables within strings uses more memory than string
concatenation. When writing a PHP script in which memory usage is a concern,
consider using the concatenation operator (.) rather than variable parsing
Thus, I think that it is better to use Concatenation instead of
Interpolation.
Since it provides Performance, both on Speed and Memory Usage.
There is a benchmark available here:
http://us2.php.net/manual/en/function.print.php#66392

I absolutely agree with unobtrusive JavaScript, but I do disagree with you slightly on using external files. Generally speaking i keep large bits of code (Especially libs) in external files, but a few lines of script for a form that appears on one page I'll often be put in the head section. This way the JavaScript is in the same file as the template for which it is associated. My template engine will relocate the JavaScript to the section at compile time. Cheers, Rob. -- ...

I know this isn't exactly a php related question but due to the
quality of answers ive seen lately ill give this a shot. (yes yes im
smoothing up the crowd before the question)
I have a weblog system that i am creating, the trouble is that if a
user links to an external image larger than 500pixels in width, it
messes with the whole layout.
I had found some regex code im using atm but its not good at matching
the entire image tag. It seems to ignore properties after the src
declaration and not match tags that have properties before the src
declaration .
preg_match_all("/\< *[img][^\>]*[src] *= *[\"\']{0,1}([^\"\'\ >]*)/i",
$data, $matches);
print_r($matches);
This currently makes two arrays for me, the source location from all
img tags and a large part of the tag itself. But not the entire tag.
What i do is i match the img tag, find the src, get the image
properties, and if the width is more than 500, i shrink it down and
add width="X" and height="Y" properties to the image tag.
How can i match an image tag correctly so it does not cause any issues
with how the user adds the image.
You could set a class attribute for the image in
html and scale it in css. An img {width: 100%;}
would hold the size to the maximum of the parent.
Cheers,
tedd

Ideally, yes I do want to convert the doc file to an html file. I've tried wvWare and I really like it. Unfortunately, the hosting provider refuses to install it since you do need root access for the installation. catdoc, doesn't appear to preserve text format, so that would defeat the purpose of uploading word documents. word2x has also potential, however, I don't have root access on this system. Appreicate the feedback. With these restrictions in mind, is there any other solutions that you can think of? Not really. If you're doing this for a client, i'd tell them to find a new host or drop the idea of converting user-supplied MSWord files. Do the files really need to be converted? Aside from the fact that it's lame, you could just serve up DOC files to the browser. No, i hate that idea. Forget it. How big are these files, anyway? Could you, instead, have the users supply the information through a WYSIWYG widget (widgEdit, FCKEditor, etc.) that would do the mark-up itself? Do you have shell access to the server? If so, can you see if any of these tools are already available. Do the conversions need to be immediate?

Don't wonder.
Run ab (Apache Benchmark) and find out.
Or use valgrind/callgrind to find out.
Or use wget to find out.
Or use that whack-a-mole benchmark or SuperSmack or whatever it is.

Any program can be run as a "service" (Un*x: daemon)
Writing that program to do something useful and, more so, efficient,
is a bit challenging.
Here's a sample "talkback service" that just spits out whatever you

Re: [PHP] manual vs. meta refresh
Rob, What you suggested, which matches the theory of what I and others suggested, would certainly work as an ID that changes is involved. If you read the specific posting by Richard Lynch, which is what I was replying to, you will note he suggest refreshing to a static 'was_meta_refresh_before' link which of course won't work as refreshing manually at that point will be indistinguishable from a true meta-refresh after the redirect has occurred. Anyways; this thread seems done, there are several solid suggestions on how to do it properly.

Re: [PHP] manual vs. meta refresh
You don't do it there. You do whatever it is you have to do in the URL before you re-direct. Though I guess if you want different output on that page, you would need to set something somewhere, be it session, database, or a cookie.

I think you're missing the point Richard. Yes you can detect the meta redirect or manual refresh using your method. But only the first can be detected because when the page is served up to the browser again either the special meta redirect URL is active, non special normal URL is active, or a super special I'm redirecting but don't count me URL is active. Now what happens when the user does a manual refresh again? It's not about output, it's about detecting subsequent refreshes and determining again the source of the refresh. You must have some kind of session tracking system in place, be it a regular session or a database query that can check if an ID was already detected that indicates to discount the page load from any statistics.
