This is my code above.
I read a sentence that begins with include from a txt file(snortconf.txt) . Then I seperate the sentence and keep the last part of it with str_replace(). An other value, the value from a checkbox is submitted to its own page and the value is used for a Comparation with the value from the txt file.

When I echo both the values between quotes, so invisible spaces are revealed if they're there, they are
exactly the same. However, in the last if-loop where I compare $rule with $breaker2 I get false.
How is this possible ????? I have no clue.

snortconf.txt contains this:
[code]TEST
TEST
TESTNUMMERDRIE
include $RULE_PATH/exploit.rules
TESTJE[/code]

A little help would be great.

PS: the comments are test-echo's, so I can see where the script goes and where it doesn't go, etc. So don't mind the language of the comments...

Thx
Grande

No, if you just do an "echo $var" to the screen the web browser will compress two or more adjacent spaces into one. In order to really see all the spaces either surround the variables with the '<pre></pre>' tags or replace all spaces with the special space "&nbsp;".

I would compare the trimmed values.

so this doesn't do the trick :
[code]echo "\"".$breaker2."\"";[/code]

No.

Run this script to see the differences:
[code]<?php
$str1 = ' this string has many spaces at the end          ';
$str2 = ' this string has many spaces at the end ';
echo '"' . $str1.'"<br>';
echo '"' . $str2.'"<br>';
echo '<hr>';
if ($str1 == $str2) echo 'The strings are equal<br>';
else echo 'The strings are not equal<br>';
echo '<hr>';
echo '<pre>"' . $str1 . '"'."\n";
echo '"' . $str2 . '"</pre>';
echo '<hr>';
if (trim($str1) == trim($str2)) echo 'The trimmed strings are equal<br>';
else echo 'The trimmed strings are not equal<br>';
echo '<hr>';
echo '<pre>"' . trim($str1) . '"'."\n";
echo '"' . trim($str2) . '"</pre>';
?>[/code]
