preg_replace help

[Alexander Ross]

I dont think I'll ever understand regular expressions ... I need to do th
efollowing and I just don't know where to start:

$haystack = "How much wood would a wood chuck chuck if a woodchuck could
chuck wood?";
$needles = ("wood","chuck" ,"wood chuck");


I want to replace every needle with an anchor tag like this:

<a href="def.html? word=wood">wood </a>
<a href="def.html? word=chuck">chu ck</a>
<a href="def.html? word=wood%20chu ck">wood chuck</a>

How do I do this?!?


Thanks
Alex

Re: preg_replace help

<?php

$lines = array ('How much wood would a wood chuck chuck if a woodchuck could
chuck wood?');

$old = array('wood', 'chuck', 'wood chuck','','','' ,'','');
$new = array('<a href="def.html? word=wood">wood </a>','<a
href="def.html? word=chuck">chu ck</a>','<a
href="def.html? word=wood%20chu ck">wood chuck</a>','','','','' ,'');

foreach ($lines as $line_num => $line) {
echo str_replace($ol d, $new, $line);
}

?>

Hope this helps you...

Re: preg_replace help

thanks for the reply, but this wouldn't work ....

in the first iteration of the for loop, it would replace the "wood" in "wood
chuck"; then in teh third iteration. "wood chuck" would not be found


Any other thoughts?

Very similar to the "preg_repla ce and metatags..." thread:

<?php
$string='How much wood would a wood chuck chuck if a wood'."\n".'chu ck
could chuck wood?';
$search = array('wood\s*c huck','wood','c huck');
$pattern='`('.j oin('|',$search ).')`iUs';

preg_match_all( $pattern,$strin g,$matches);
$search=$matche s[0][0];
$term=preg_repl ace('/(\r\n|\r|\n)/',' ',$matches[1][0]);
$string=str_rep lace($search,'< a href="def.html? keyword='.
urlencode($term ).'">'.$term.' </a>',$string);
?>
