substr(string,start,length)slice array php
array_slice() function is used to get selected part of an array.
Syntax:
array_slice(array, start, length, preserve)
*preserve = false (default)
If we put preserve=true then the key of value are same as original array.
Example (without preserve):
<?php
$a=array("red","green","blue","yellow","brown");
print_r(array_slice($a,1,2));
?>
Output:
Array ( [0] => green [1] => blue )
Example (with preserve):
<?php
$a=array("red","green","blue","yellow","brown");
print_r(array_slice($a,1,2,true));
?>
Output:
Array ( [1] => green [2] => blue )Copyright © 2021 Codeinu
