If we have a very large array values in Indexed or Associative array, we have to search or filter the particular array value or key.
Array_Search function is used to find the value.
This function used to search an array for a value and returns the key.
<?php
$search =array('a'=>'php','b'=>'css','c'=>'html,'d'=>'dssd','e'=>'eeee',f=>'fdfd','g'=>'dsfsd',....);
echo array_search('css',$search);
?>
In the Given example, we have to find whether “CSS” Find or not in the array. It prints the key of the value.
Output
b // output
Explaination
array_search is used to search the array value(‘css’) and returns the value’s key(‘b’);
2. In_array()
In_array is simillar to the array_search
In_array Functions is used to find the value in the array list
using this function you can find the value is present or not in array queue.
syntax: In_array();
