str_replace , / not working

Question

I need to find \ in a string.

Example

$replacevalue = "%20";
$area = "test\abc.htm";
$valuetoreplace = "\";
$area = str_replace($valuetoreplace,$replacevalue, $area );

But it seems like the page goes into a loop or somthing if i do the same with / there are no problem please help

add slashes to your $valuetoreplace – Eugene Manuilov Jan 28 '13 at 07:30 — Eugene Manuilov, Jan 28 '13 at 07:30
The page should have died with a fatal "Parse error". – Salman A Jan 28 '13 at 08:55 — Salman A, Jan 28 '13 at 08:55

You need to double your \s as it is an escape character for strings... So:

% php
<?php
$area = str_replace("\\","",'test\abc.htm');
echo $area."\n";
?>

Yields... testabc.htm

try this:

$replacevalue           =   "%20";
$area               =   "test\abc.htm";

$valuetoreplace     =   "\\";
$area               =   str_replace($valuetoreplace,$replacevalue, $area );

or another solution is in this post

Well "\" this character is an escape character so compiler refers to it as an escape not as a "\", just add another one so it will escape itself "\" and your code will work
