Hi. How about an identifier to remove an occurrence of substring. but single remove. example below:

//if ($remove(aaabb,b)) echo $ifmatch
* above will return aaa as we all now.

//if ($removex(aaabb,b)) echo $ifmatch
* above will just remove the first matched occurrence which will return aaab

I made a worked-around snippet. but I wish to see this feature to be built-in.

Nice idea. Better yet, make it $removex(string,sub,N[,sub,N,...]), removing the Nth occurrence of <sub> in <string>. N could be negative (removing from the right) or zero (removing all occurrences).

That's even better qwerty

Just to throw a spanner around the room, should each following "sub,N" be based apon the original string or the resulting string as it stands at the time of reaching the said "sub,N" ?

Heh, good point. Maybe the name $removex should be reserved for the identifier similar to $replacex. I can't come up with a short and descriptive name for this one ($removeone/$removeonex doesn't sound quite right).

$remove already targets the string as it is when it reaches the nex parameter
$remove(abed,abe,ed)
Would leave Null when you target the input string alone but it returns d because "abe" was removed and ed wasn't found anymore.
$removex() should target the input string alone (like $replacex does) and shouldnt be complicated with N parameters IMO because then $remove and $removex wouldn't work in the same matter as $replace and $replacex .
Maybe $removeps() would be a good name ? and $removepsex() ps meaning position sensitive.

Ps: explanation not targeted at anyone in this thread

EDIT: Just realised $removepsex() would be subject to jokes and laughter :tongue:

/me jokes and laughs...


pee sex haha
