Hello dear readers! welcome back to another section of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP in_array() Function.

PHP built-in in_array() function searches an array for a specific value. If the third parameter strict is set to TRUE then the in_array() function will also check the types of the $value.

Following below is the syntax to use this function -

in_array ( $value,  $array [,$strict ] );


Parameter Details

Sr.NoParameter & Description
1

The value to be search in array.

2

3

strict(Optional)

If this parameter is set, the in_array() function searches for the search-string and specific type in the array.


Return Value

This PHP function returns TRUE if the value is found in the array or, False otherwise.

Example

Try out the below example -

<?php
   $mobile_os = array("Mac", "android", "java", "Linux");
   
   if (in_array("java", $mobile_os)) {
      echo "Got java";
   }
   
   if (in_array("mac", $mobile_os)) {

   }
?>
