help in regular expression

[ruba]

Hi all,

I need help in regexp.

I have this statment

$website = 'http://www.sample.com/';
$str = preg_replace("/<A[ \r\n\t]{1}[^>]*HREF[^=]*=[ '\"\n\r\t]*([^ \"'>\r\n\t#]+)[ \"'>\r\n\t#>][^>]*>(.*)<\/a>/isU", '<a href="'.$website.'$1">$2</a>', $str );

where Str is an HTML page code, It make the links with full path.

my problem is it cover all links, what ever it's a full path eg.

<a href="http://www.sample.com/page.html">page</a>

I want to update this regular expression, to make it not change the full path only the small links for example

<a href="page.html">page</a>

make it

<a href="http://www.sample.com/page.html">page</a>

please help. 😕

add an if statement and use preg_match to check if http:// is in $website

You could use an assertion:

<?php
$website = 'http://www.sample.com/';
$str = "This is <a href='test.php'>a test</a>.
Don't change <a href='http://www.example.com/page.html'>this link<a>.";

$regex = '#(<a\s[^>]*href\s*=\s*[\'"])(?!http://)([^>]*>)#is';
$str = preg_replace($regex, "$1$website$2", $str);
echo htmlentities($str);
