Getting everything before the -

[DavidRoberts60]

Hello,

 

Is it possible when a variable is passed through to another page (example something like 728334-sdfnjsdh) just to grab the number bit?

 

In other words, get everything before the - symbol?

 

Thanks.

if you don't care what characters come before the -, and if they are not always going to be digits, you can use this preg_match

 

$string = "728334-sdfnjsdh";
$pattern = "~(.*)-~";
preg_match($pattern,$string,$matches);
print_r($matches);

 

$matches[1] will hold the value that you want. If you expect the characters that come before the - to always be digits, then you can use something like this

 

$string = "728334-sdfnjsdh";
$pattern = "~(\d*)-~";
preg_match($pattern,$string,$matches);
print_r($matches);

 

where again, $matches[1] will hold your value
