How to explode a string on upper case characters Problem You have a string with the following value “thisStringMustBeSplittedAfterUpperCase” and you want to obtain every word separately in an array, splitted after upper case. Solution

$chunks = preg_split('/(?=[A-Z])/', $string, -1, PREG_SPLIT_NO_EMPTY);

1	$chunks = preg_split('/(?=[A-Z])/', $string, -1, PREG_SPLIT_NO_EMPTY);

Output The output of the $chunks array obtained with a var_dump($chunks) will be:

array (size=8)
  0 => string 'this' (length=4)
  1 => string 'String' (length=6)
  2 => string 'Must' (length=4)
  3 => string 'Be' (length=2)
  4 => string 'Splitted' (length=8)
  5 => string 'After' (length=5)
  6 => string 'Upper' (length=5)
  7 => string 'Case' (length=4)

array (size=8)

0 => string 'this' (length=4)

6 => string 'Upper' (length=5)

7 => string 'Case' (length=4)

Solution in a function

function upperCaseSplit($string){
    return preg_split('/(?=[A-Z])/', $string, -1, PREG_SPLIT_NO_EMPTY);
}

$string = 'thisStringMustBeSplittedAfterUpperCase';
var_dump (upperCaseSplit($string) );
