that's because you're testing to see if '\n' is "\n"...single quotes
mean:
interpret the text between literally, so '\n' is a backslash followed by
n...doulbe quotes mean: interpolate the value, so \n becomes a newline...

Subject: [PHP] simple regexp question - validating new line chars
Hi everyone:)
I need to validate a string that comes from a submitted form.
There's nothing unusual in it... but the problem part showes up, when I
need to validate a new line character...
I have tried many diffrent variations of the code and I have
ended up on something VERY simple:
<?php
$regexp='\n';
$text="\n";
echo $text;
if (true==eregi($regexp, $text))
{
echo 'ok';
}
else
{
echo 'error';
}
?>
Unfortunately this script results with "error" ;(
Does somebody know how to make this regexp to work?
Maybe it is a bug?
I am using php 4.0.6 on windows 2000.
I will appreciate any feedback about this ;)
