GenesisBits :
I have a string as so:
[[EARTH]] [[Machine]] [[Monster Card|monsters]]
If this card is [[Link Summon]]ed: You can [[Add a card|add]] 1 "[[Ancient Gear]]" monster or 1 "[[Geartown]]" from your [[Main Deck|Deck]] to your [[hand]]. You can [[target]] 1 [[Spell Card|Spell]]/[[Trap Card|Trap]] you [[control]] and 1 [[face-up]] monster your opponent controls; [[destroy]] that card you control, and if you do, change that opponents monsters [[ATK]]/[[DEF]] to 0 until the end of this [[turn]]. You can only use each [[effect]] of "Ancient Gear Ballista" [[once per turn]].
I'm using the following piece of code to remove all square brackets:
$stringout = str_replace(array('[[',']]'),'',$stringout);
However, when the brackets contain | character, I need to keep only the text after this character.
So from this:
[[Monster Card|monsters]]
To this:
monsters
I tried this:
$stringout = str_replace(array('[[|',']]'),'',$stringout);
CBroe :
Really more a job for preg_replace and regular expressions, than simple string replacement.
$result = preg_replace('#\[\[(?:[^\]]*\|)?([^\]]*)\]\]#', '$1', $input);
(?:[^\]]*\|)? is a non-capturing group, that allows for an optional ...| part. Optional, so that $1 will always refer to the second part, which would either be the rest after that, or the full content between [[…]], if there was no |.
