I have an expression
((( 5339) * ( 1 + Cess Duty + 0.14 * ( 1 + 0.02 + 0.01) + Packing & Forwarding) + Packing & Forwarding fixed))
In the above expression the value to be replaced is coming from sql query in which "Packing & Forwarding" is coming before "Packing & Forwarding fixed". When i use replace function both "Packing & Forwarding" gets replaced and in second place only "0 fixed" remains. How to replace this value.
Anybody can help me.....
Thanks in advance

can someone explain me what this expression does exactly
Set your own pattern of preg_replace function.Default: /[,.\-:><()!?\n]/
in case of problems try this: /[^a-zA-Z0-9\200-\377]/

I want to do this - whenever I get a filename stored in a variable (f.e. $file1), I want to remove all dots from this variable, EXCEPT if they are in last four or five spots (so I dont delete file extension.

I'm a newbie (i know more chinese than regexp) but i solved my problem. If it is of any good to any other user, here is the code:
function auto_link($foo) {
$foo = preg_replace('/(?<!\S)([A-Z_\-\w-.]+)(@)([A-Z_\-\w-.]+)\b/i', '<a href="mailto:$1@$3">$1@$3</a>', $foo);
$foo = preg_replace('/(?<!\S)((http(s?):\/\/)|(www\.))+([\w.\/&=?\-~%;]+)\b/i', '<a href="http$3://$4$5" target="_blank">http$3://$4$5</a>', $foo);
$foo = preg_replace('/(?<!\S)((ftp(7?):\/\/)|(ftp\.))([\w.\/&=?\-~%;]+)\b/i', '<a href="ftp$3://$4$5" target="_blank">ftp$3://$4$5</a>', $foo);
return ($foo);
}
I hope my code ain't that bad at all.

Hey man, could you help me? your script is the best I found on the web to create auto links from url's and e-mails. Although I have an e-mail with an hyphen (-) and the replace ends there, someting link this:
abc@be-f.gh => abd@be
what can I do to repair this? I'm trying to understand the syntax of regexp but it is going to take a while and my time is running out.
Many thanks in advance

This is for the person who wished to see a more practical example of hyperlinking an email address or URL.
function autolink($foo) {
$foo = preg_replace('/(?<!\S)([\w.]+)(@)([\w.]+)\b/i', '<a href="mailto:$1@$3">$1@$3</a>', $foo);
$foo = preg_replace('/(?<!\S)((http(s?):\/\/)|(www\.))+([\w.\/&=?\-~%;]+)\b/i', '<a href="http$3://$4$5" target="_blank">http$3://$4$5</a>', $foo);
$foo = preg_replace('/(?<!\S)((ftp(7?):\/\/)|(ftp\.))([\w.\/&=?\-~%;]+)\b/i', '<a href="ftp$3://$4$5" target="_blank">ftp$3://$4$5</a>', $foo);
return ($foo);

Compared to other manuals, I have read this manual explains Simply and in detail. This gives a better understanding of Regular Expression usuage.
I would be more useful, if u give real time examples(extracting emailids, links,etc.,)

I had lot of confusions regarding regexp before reading this session. It really helped me. Thanks.

[A-Z]{1,3}
3 uppercase letters
You must mean 1 to 3 uppercase letters

Nice, but you forget the "|" ( OR ):
if (preg_match("/(php|asp)/", "asp")) {
print "Got it!";
}
matches for "php" OR "asp".
