Replace Repeated Occurance of Character with 1 of Said Character

I know the title probably didn't make sense, so I'll clarify what I mean.

What I'm looking for is a way to cut down repetition of a character (for example, aaaa) down to just 1 of that character (a), so aaaa -> a

Thank you!

 

I think you have to use trim function ...

 

The trim function only works with the beginning and end of the string. I'm looking for something that trims in the middle.

 

Try a preg_replace:

$string = preg_replace('/aaaa/','a',$string);

PHP:

Let us know if your $string could contain bbbb, or cccc, or other situations that aren't necessarily pre-identifiable.

 

jestep, I'm only looking for repeated occurrences of one character, but is there a way to cut down repeated occurrences (starting with 2 or more) down to just one?

So the scenario is, I don't know if there will be 2, 3, 4, or even more As, but if there are, I need to trim that down to just 1.

 

preg_replace('/[a]+/', 'a', $str);

PHP:

Hope that helps

 

Thank you Wallity!!
