how to find room_id this array

Answer 1

The array_search() function searches an array for a given value and returns the key. The function returns the key for val if it is found in the array. It returns FALSE if it is not found. If val is found in the array arr more than once, then the first matching key is returned.

Syntax array_search(val, arr, strict) Parameters val − The value to be searched

arr − The array to be searched

strict − Possible values are TRUE or FALSE. Search for identical elements in the array, set to TRUE.

example :-

<?php
$arr = array("p"=>20,"q"=>20,"r"=>30,"s"=>40);
echo array_search(20,$arr,true);
?>
