It made unwanted modifications; observe: The following is an emoticon: =o) The following is a formula: a=b*c The following is an emoticon: =) The following is a formula: a=*c

It depends on the data. I think it's a safer approach because we're making two verifications rather than one: (1) the data must appear after an equals sign; and (2) the data must appear before a double quote. Otherwise, it could botch up something like this: <pre> <?php $str = '<H1=2D"some_value">The following is an emoticon: =o) The following is a formula: a=b*c'; $str = preg_replace('#(?<==)\w+#', '', $str); echo $str; ?> </pre>

$str = preg_replace('#(<[^=>]+=)(\w+)("\w+">)#', '$1$3', $str); I added > to the character class so it will not match into another tag should the originating one not have an equals sign. There's no need for /e. Another approach with less captures, should it fit the context of the data: $str = preg_replace('#(?<==)\w+(?=")#', '', $str);

<pre> <?php $tests = array( 'username:password@host', 'username:password@host:port/username', 'username:password:username@host:port/username', ); foreach ($tests as $test) { echo "<b>$test</b><hr>"; $pieces = preg_split('%?=[^@]+\z)%', $test); print_r($pieces); } ?> </pre>

<pre> <?php $data = <<<DATA <HTML> <HEAD> </HEAD> <body> <table align="center" width="771" height="166" border="0" cellpadding="0" cellspacing="0"> <tr> first</tr> <tr> second</tr> </table> <table> <tr>matchthis</tr> </table> </BODY> </HTML> DATA; preg_match('%<table[^>]*>(??!</table>).)*?matchthis.*?</table>%s', $data, $matches); print_r(htmlspecialchars($matches[0])); ?> </pre>
-
You must escape / because it is also serving as the pattern delimiter. <pre> <?php $str = '16cm, 2 columns 1/2'; preg_match_all('%\d+(?:[\./]\d+)?%', $str, $matches); foreach ($matches[0] as &$match) { if (strpos($match, '/') !== FALSE) { list($num, $den) = explode('/', $match); $match = eval("return $num / $den;"); } } echo $product = array_product($matches[0]); ?> </pre>
-
Will you be making many changes? parse_ini_file may be the better approach.

You mean a total of the totals? Create an array for the totals, push each one on, and use the same array_product approach array_sum.

No stripping is needed: <?php $str = '16cm, 2 columns'; preg_match_all('/\d+/', $str, $matches); echo $product = array_product($matches[0]); ?>
-
It only covers -, a-z, white space, ., ?, and !. Is that enough? No one is going to throw in @, #, $, %, &, *, etc? The parens are not needed: #[-a-z\s.?!]+#i.
-
Try /^[^=\s]+\s*=\s*.+$/m.
-
That's it as is? It has no line breaks?
-
Be where? I used a function in my example because I didn't have an include. Whatever functions you call have to exist.
-
I use it in all of my examples because it's oftentimes required for printing arrays and such; see http://www.w3schools.com/TAGS/tag_pre.asp. You can disregard. Yes.

<pre> <?php $string = "Woo, [countdown]1230163200[/countdown] until Christmas. That means its [countdown]1230768000[/countdown] until 2009."; function countdown ($in) { ### Calculations here. return $in; } echo preg_replace('%\[countdown\](.*?)\[/countdown\]%e', 'countdown("$1")', $string); ?> </pre>
-
Will there be only one pair, or multiples?
-
Anything after the ending delimiter is considered a modifier.
-
How about something generic like this? <pre> <?php $data = "I'm using preg_match_all. Sorry, I'm just not familiar with regex because I usually just google what I need. But overall I just need to find a regex to locate emails with and without parenthesis around it. e.g. [email protected] and ([email protected])."; preg_match_all('/\b[^@\s]+@\S+?\.[a-z]+\b/i', $data, $matches); print_r($matches) ?> </pre>
-
Why so many parentheses? What preg_ function are you using? Are you using the matches?

For more Perl information see learn.perl.org or perlmonks.org. You can also try our Other Languages board, but it is nowhere as comprehensive. -
