PHP Bug Type: *Regular Expressions
Bug description: Backslash and regular expressions
Hello,
I have to write a program which replaces backslashes by slashes into HTML code. I
would like to do this using regular expressions.
Unfortunately, there may be a problem in pattern matching as PHP does not seem to work
properly as soon as I add some backslashes in my patterns...
Here is a small example which illustrates the problem:
<?
$test = "X\\X"; // $test is a string containing a backslash
echo $test."\n";
echo preg_quote($test)."\n";
echo preg_match("/X\\X/", $test)."\n";
?>
The output of this program is the following:
X\X
X\\X
0
The '0' means that the preg_match failed... But the pattern of this preg_match was the
string $test quoted by preg_quote to become a valid pattern... (as you can see on
second line of the output).
So this preg_match should output '1', shouldn't it ??
Thanks in advance for any help or advice,
Olivier Roos
