square brackets

[Zugzwangle]

hi, what would the regex be, to find all content between square bracket including the brackets themselves? for example I want to find and delete [color=blue:2cd68fd71f] and [/color:2cd68fd71f]

[nevvermind]

$x = '[color=blue:2cd68fd71f] and [/color:2cd68fd71f]';

$pattern = '#\[[^\]]+\]#';

$x = preg_replace($pattern, '', $x);

// now $x has this value: ' and ';

Replaces "[any_character]" with an empty string.
Experiment with different inputs; maybe you'll need a more specific pattern.

Also, depending on the format of the file, maybe some parser would be appropriate. Regex tends to produce chaos.

For example:

// for this input:
[color=blue:2cd68fd71f] [sdfsdf]and [/color:2cd68fd71f]

//... the above script will output:
' and '
