Today’s chalenge: How to remove the duplicate values from a PHP array?
after short search i found solution array_unique.
How this function works:
<?php
$input = array(1, 2, 2, 3, 3, 4);
$result = array_unique($input);
var_dump($result); ?>
will output:
array(4) {
[0]=> int(1)
[1]=> int(2)
[3]=> int(3)
[5]=> int(4)
}
Remember: Output of array_unique() will have the same key of input array.
