Split array into two on the basis of value - php

Question

I want to split array into two on the basis of value.
For example
Array(
[25] => Korea Strawberry (Pkt) 250g
[26] => *8887187338308
[27] => PROM Mix 2#38.9G
[28] => 19.90*2 38.90 Z
[29] => 0.45*2
[30] =>
[31] =>
[32] => Total with GST # 6%
[33] => Rounding
[34] => Total
[35] => Tender
[36] => Master 0003 App: 807946
[37] => Change
[38] => GST Analysis Goods Tax Amount
[39] => S = 6%
[40] => Item 3
[41] => Qty 4
[42] => Total Saving 9.44
[43] => 56.94
)
I want it to be in two parts. One all the values before Total with GST # 6% second all remaining values.
How can I do that. I tried array_diff() and other methods but didn't work as what I want.

Answer 1

You could get the key number for Total with GST # 6% using array_search then split the array using 2 loops.
$array = Array(
[25] => Korea Strawberry (Pkt) 250g
[26] => *8887187338308
[27] => PROM Mix 2#38.9G
[28] => 19.90*2 38.90 Z
[29] => 0.45*2
[30] =>
[31] =>
[32] => Total with GST # 6%
[33] => Rounding
[34] => Total
[35] => Tender
[36] => Master 0003 App: 807946
[37] => Change
[38] => GST Analysis Goods Tax Amount
[39] => S = 6%
[40] => Item 3
[41] => Qty 4
[42] => Total Saving 9.44
[43] => 56.94
);
$value = 'Total with GST # 6%'; //This can be dynamically filled
$split = array_search($value, $array)
for($i=0; $i<$split; $i++) {
$newArray1[] = $array[$i];
}
for($i=$split; $i<count($array); $i++) {
$newArray2[] = $array[$i];
}
unset($array); //Now it's split we can unset the $array variable

Answer 2

You are looking for array_slice.
Just be careful about using it on associative arrays, or arrays with arbitrary numerical keys.
