How to have PHP Implode / Explode functions like in Obj-C ?

[laurent]

Implode & explode functions are sometimes very usefull.
Here's the trick :

Explode like :

Supposing that you've got an NSString named "string" containing several elements separated by a pipe "|", you can get an array of each strings just like this :

Code: Select all

NSArray *myElements = [string componentsSeparatedByString: @"|"];


Implode like :

Now to get the reversed result (so have an Array of NSString and merging them into a single NSString "glued" with a separator string, do that :

Code: Select all

string = [myElements componentsJoinedByString: @"|"];


Don't forget that the glue/unglue string (the seperator) is... a string. So you also can use complex combination, not only one char.
