in_array

The What

Syntax

bool in_array ( 
	mixed $needle,
	array $haystack, 
	[, bool $strict = FALSE]
);

Description

This construct, in_array checks if a value (not the key only the value) exists within the given array.

Parameters

needle: The value you want to search for within the array (haystack).
haystack: The given array to be searched.
strict: optional When set to TRUE, it will check not only for the value to be equal, but also the data type matches the needle.

Return Values

Returns TRUE if the value does exist in the array; else you’ll get a FALSE back.
