Can someone explain the difference between these two lines of code?
preg_replace("/[^0-9]/", '', $Phone);
preg_replace('/[^0-9\/+]/', '', $Phone);
Ive been hunting online and cant seem to find anything explaining the extra "/+"
The following matches anything that's not a digit.
/[^0-9]/
The following matches anything that's not a digit, /, or +:
/[^0-9/+]/

What I'm trying to do is remove a string after the dash if the string after the dash matches what is appended.
For example it'd be like: if endofstring is equal to givenstring, remove dash and everything after, else keep the dash
Thanks for any help!
$string='Hello this is the-end';
$remove='end';
$i=strrpos($string, $remove);
if ($i===strlen($string)-strlen($remove)) $string=substr($string, 0, $i-1);
var_dump($string);

preg_match('~&([^#]*)#~',$content,$match);

I want a regex that will help me to get the 4 numbers before the cc.
The RegEx must contain the cc to identify these exact number.
Example:
1600cc
You should use:
/(\d{4})cc\b/
\b ensures that "cc" is at the and of the word.
preg_match('/(\d{4})cc/', $string, $match);
$match[1] will contain the number.

I suck at regexp but i'd like to just do a simple filter where / is replaced with 1, " is replaced with 2 and < is replaced with 3.
I'd appreciate an example where the syntax would be straight forward, i'd like to run this filter through the input of a get variable provided by the user. A syntax like:
replace(/,1)
replace(",2)
replace(<,3)
.
Thanks.
I really don't see the need for regex here.. You can just use str_replace
E.g.
str_replace('/', '1', $_GET['var']);
