2 preg_replace question

[teomanersan]

hi guys..

i`d like to ask how to accomplish using urlencode() function inside a preg_replace function and inverse of preg_replace..

$string = preg_replace('#\[star](.*?)\[/star\]#is','<a href="blabla.php?ara=\\1">*</a>',$string);

works fine.. but i have to add a urlencode() to the link... so i tried some stuff like below

$string = preg_replace('#\[star](.*?)\[/star\]#is','<a href="blabla.php?ara='.urlencode(\\1).'" >*</a>',$string);

which is not working.. it`s encoding \\1 and not the $string.. how can i make it encode the string ??

the second question is how can i take the inverse of this preg_replace().. simply when i get
$string = <a href="blabla.php?ara=\\1">*</a>' , i want it to write [star]$string[/star]

thanks for your time..

good coding..

You'll want to use the e modify like so:
$string = preg_replace('#\[star](.*?)\[/star\]#ise','<a href="blabla.php?ara='.urlencode(\\1).'" >*</a>',$string);

[/code]
