Regular exp problem

[seanlyon]

Hi,

I am trying to qualify any relative path using preg_match/preg_replace.

Here is what looks like before:

href = " / some_path" or
href = " some_path" or
href = some_path or
href = / some_path

When I do preg_match like the following,

if(preg_match("/href[^=]=\s/i", $data)
.....

I get an error
(Parse error: parse error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}')

The problem is from \s. Can anyone tell me how do I represent multiple white space here? (I have tried [[:space:]], [' '], [ ] etc. None of them worked with )

Thanks a lot.

You need to double escape the s \s as double quoted strings eat up the first one.

\s = s
\s = \s

Your regex needs to look like this

<?
 $data = 'href=http://www.phpbuilder.com/board/showthread.php?s=&threadid=10259608 hello';
 preg_match("/href[^=]*?=\\s*?[^\\s]*/i", $data , $matches );
 print_r( $matches );
?>
