PHP Bug Type: *Regular Expressions
Bug description: Regular Expression Syntax
Description:
------------
The escaping the dash character (-) in a characters set of a regular
expression is ignored. It works correctly in Perl.
Reproduce code:
---------------
<? // -*- C -*-
echo "<html><body>";
$email = "[EMAIL PROTECTED]";
$email = "[EMAIL PROTECTED]";
if (eregi( '^[a-z0-9]+[a-z0-9\-\.\+_]*\@([a-z0-9\-\.]+\.[a-z][a-z]+)$',
$email)) {
echo "Valid";
} else {
echo "Invalid";
}
echo "</body></html>
";
?>
Expected result:
----------------
This should print valid, but prints invalid. I know the work around is to
put the -, without the escape, at the end of the regex.
Perl works correctly:
#! /usr/bin/perl
$_ = "[EMAIL PROTECTED]";
$_ = "[EMAIL PROTECTED]";
if ( /^[a-z0-9]+[a-z0-9\-\.\+_]*\@([a-z0-9\-\.]+\.[a-z][a-z]+)$/) {
print "Valid\n";
} else {
print "Invalid\n";
}
