PHP Bug Type: *Regular Expressions
Bug description: preg_replace incorrect output with *
PROBLEM: preg_replace does not return the proper value with
a * in the regular expression.
INPUT: $_POST['bannerad_url'] = 'www.canoe.ca';
PROCESS CODE:
$_POST['bannerad_url'] = trim($_POST['bannerad_url']);
if (preg_match ("/^http:\/\/(.*)/i",
$_POST['bannerad_url']) > 0)
$bannerad_url = $_POST['bannerad_url'];
else
$bannerad_url = preg_replace ("/(.*)/", "http://\$1",
$_POST['bannerad_url']);
OUTPUT: echo $bannerad_url; -------> http://
www.canoe.cahttp://
FIX:
INPUT: $_POST['bannerad_url'] = 'www.canoe.ca';
PROCESS CODE:
$_POST['bannerad_url'] = trim($_POST['bannerad_url']);
if (preg_match ("/^http:\/\/(.+)/i",
$_POST['bannerad_url']) > 0)
$bannerad_url = $_POST['bannerad_url'];
else
$bannerad_url = preg_replace ("/(.+)/", "http://\$1",
$_POST['bannerad_url']);
OUTPUT: echo $bannerad_url; -------> http://www.canoe.ca
NOTES:
I was able to reproduce this several times. It seems to be
related to the *, but replacing it with a + solves the
problem. Thanks.
