[Resolved] <link:page.html,xxx> => <a href="page.html?id=xxx">

[foxroberts]

Hi.

I want to transform this code <link:page.html,xxx> to
<a href="page.html?id=xxx"> dynamically.

I tried out alot of preg_replace stuff, but I didn't get to
manage it... thank you for any hint!

<?php 
$filename = str_replace("link:", "<a href=\"", "link:page.html,xxx\">");
$filename = str_replace(",", "?id=", "$filename");
echo  $filename;
?>

It works but maybe someone knows how to do it a bit more elegantly?

[foxroberts]

Thank you for that idea.

The problem is that this script will replace all commas
in my page... a preg-solution would be great.

$search = '%\\<link:(.*),(.*)\\>%siU';
$replaced = preg_replace($search, '<a href="$1?id=$2">', $to_replace);

Thank you very much!

oooo - much fiendishness!

The manual is as clear as mud so I'm off to hudzilla to read up on regular expressions so I can understand what the answer means!

Question: what does the U mean in the expression?

[mrhappiness]

the modifier U tells the regular expression engine to be ungreedy, that means it matches the shortest possible pattern

$to_replace = '<link:page.html,xxx>
<link:page2.html,xyz>
<link:page3.html,abc>';

test this with my regular expression and afterwards test it with my regular expression but without the U and compare the output

you culd also write (.?) instead of (.) and ommit the U but that would be one more character 😉
