Need help with a code

[dev1902]

Hello guys, i'm trying to separate something like this: 15969_D55T_000 this: 3105_C55_00148 and this : 15969_D55T_00 using php.

 

 

I have a few letter and number combination like these in a database that i already access.

 

I was wondering how i would be able to just make it 15969_D55T, 3105_C55.

 

I want help with a general php code that will help me to get ride of the extra "_xxx or _xx or _xxxx" after "xxxx_xxx"

 

As i said before, All this information is on a database that I access.

 

Thank you Very Much.

You can break it apart by underscores and then put the first two pieces back together.

 

[edit] Or strtok

strtok($string, "_") . strtok("_")

Thanks, I actually ended up using  preg_replace as it was easier than the methods you suggested. Thank you though.

Don't use regular expressions unless you absolutely must. They're much slower and more difficult to understand than simpler functions like explode().

I know, but with the script I already had, that was really the best choice. It runs well for what me.

 

It was extremely easy to write :  preg_replace("/_[0-9]{0,5}$/", "",$Id);

Requinix's example is just as easy and is quicker.

 

 

<?PHP

  $Id = '15969_D55T_000';
 
  $Id = strtok($Id, "_") .'_'. strtok("_");
 
  echo $Id;
 
?>

They're over 25k and some of them only have 1 _ and some have more/less numbers . 

 

Example : 15607_249

or 

357_C679_50984

The code I posted works for those examples too.

 

Just need this line:

$Id = strtok($Id, "_") .'_'. strtok("_");

I only wrote the rest as an example, so you can see it's output.

Thanks a lot guys. My client seems to be fine preg_replace. I will look into it more though. Thanks again.
