如何在PHP中每次出现字符串时拆分数组

Question

Eg: I have an Following array
$array = array("abc","def","ghi", "jkl", "mno", "abc", "pqr", "stu", "vwy", "abc");

And i need to split this array for every occurrences of a string called "abc" I have tried array_chunk not helped for me..

A simple way using foreach. Just going through all element in an array and split it on the condition.

<?PHP
$array = array("abc","def","ghi", "jkl", "mno", "abc", "pqr", "stu", "vwy", "abc");
$acc_arra = array();
$i=0;
foreach($array as $occurrences)
{
    if($occurrences=='abc') //checking occurance
    {
        $i++;
    }
    else
    {
        if(!$acc_arra) //To start array from 0(if first element is 'abc')
        {
            $i=0;
        }
        $acc_arra[$i][]=$occurrences; //add to array
    }

}
print_r($acc_arra);

OUTPUT

Array
(
    [0] => Array
        (
            [0] => def
            [1] => ghi
            [2] => jkl
            [3] => mno
        )

    [1] => Array
        (
            [0] => pqr
            [1] => stu
            [2] => vwy
        )
