Removing Multiple/Possible Characters From End of Variable

[ChrisC123]

I hate asking for help (some searches usually find the answer), but I can't figure this one out....

 

 

I need to strip a handful of possible characters off the end of a variable and have been playing with trim, str_replace and preg_replace with no luck. I can get them to work fine with a specific name/characters but not one that covers all possible options.

 

Our employees desktop and laptops use a standard naming convention that could have multiple characters at the end of their device name which is based on their name. I am trying to strip off all characters to just get the employee name.

 

Here are some examples of our devices name:

JDOE

JDOE_L

JDOE-L

JDOE-L2 (or any numeric range such as 2-9)

JDOE2 (or any numeric range such as 2-9)

 

I am trying to get only the JDOE from the device name.

 

 

Any help would be great. Thanks!

So the criteria is "everything up to the first hyphen, underscore, or number"?

if (preg_match('/^[^0-9_-]+/', $device, $matches)) {
	echo $matches[0];
}

Or only letters?

'/^[a-z]+/i'

That worked perfectly! Thank you so much!
