How to split array values to new array?

how to split received values of an array into a new array?

so from this:

[["+","+","+"],["-","+","+"],["*","+","+"],["\/","+","+"],

to this:

["+"],["+"],["+"],["-"],["+"],["+"],["*"],["+"],["+"],

can someone help me?

you can use regular expression : $str ='[["Z","A","B"],["-","+","+"],["*","+","+"],["\/","+","+"],'; preg_match_all("/[\"|']([^\]\[\"]+)[\"|']/i", $str, $matches); $matches[1] is your new array, print_r($matches[1]); — chokrijobs, Oct 20 '13 at 18:13

Flatten your array by looping through it

$aFlattened = array();
foreach($aOriginalArray AS $aOperators){
   $aFlattened = array_merge($aFlattened, $aOperators);
}
