Stuck on a simple thing...

zzz

I have a str that sometimes have numeric value attached.

myString
or

myString (3)

I need to remove anything past myString including space and all. myString could have variable length, so i can't really count chars and clean the rest. Tried

$myString = preg_replace('/\.([0-9]*)$/', '', $myString);

Your pattern is looking for a literal dot, and the example strings you gave dont have that in them. That might be one problem. The other thing I think is that you need to escape your paranthesis (put a backslash before them), as those have special meaning in regexes.

I'm not sure what you mean. if you just want to remove the non-integer part of a number, an (int) typecast will do. otherwise, can you put up an example of a probable input and the expected output?

I have:

My short link (21)

I need to have:

My short link

This will take out all but a to z upper and lower.

$myString = preg_replace('/[^a-zA-Z]/', '', $myString)

removing all but the characters in a given range is a bad idea. you still might get spaces, commas, japanese and other stuff removed as well.

I suggest:

$mystring = preg_replace('| *\([0-9]+\)$|','',trim ($mystring) );

That is true, but sometimes its better to include what you want rather than what you dont. For example; if you want to add white space:

$myString = preg_replace('/[^a-zA-Z\s]/', '', $myString)

Just to offer yet another solution:

$mystring = preg_replace('/\s+\([0-9]+\)$/', '', $mystring);
