Extract a special hash from a string

I'm trying to extract the following pattern {#56DS1e5R9w7v} which is :

• {
• Hash
• a-z, A-Z, 0-9 ( not necessarily an alphanumeric string )
• }

Any i开发者_C百科deas please?

Thank you

Try this pattern:

\{#([^}]*)\}

It should match all characters that are not }, and place the result in a captured group. You may want to change [^}]* to \w* or [A-Za-z0-9]* if that's problematic.

Example (also on ideone.com):

$str = "hello {#56DS1e5R9w7v} good people";
preg_match_all("/\{#([^}]*)\}/", $str, $matches);

Something like ({#[a-z0-9]+?}) ?

preg_match('/(\{#[a-z0-9]+?\})/i', $sString)

What about:

 <?php

     $code = '{#56DS1e5R9w7v}';
     $matches = preg_match('/^\{#[a-zA-Z0-9]+\}$/', $code); 

 ?>

This makes sure the string begins with a { the second char must be a #, the 3th char until } must be alpha numeric and it must end with a }.

Hope this helped!
