In this tutorial we are going to see how to separate positive & negative values from an array in PHP language.
The logic is very simple you have to loop through the array and check if the value is > 0 if yes then it is positive integer otherwise a negative integer and then just store the values in two different arrays.
Here is the snippet:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
<?php $myarr = array(12,-14,-59,90,100); //now loop through the array and separate foreach($myarr as $num){ if($num > 0){ $positive[] = $num; }else{ $negative[] = $num; } } //print both positive and negative array values print_r($positive); print_r($negative); ?> |
It’s very simple isn’t it?
I am also giving a demo script in this post so you can execute and see it:
