Question
How to find a specific value in an array?
Answers
There are two functions can be used to test if a value is defined in an array or not:

array_search($value, $array) - Returns the first key of the matching value in the array, if found. Otherwise, it returns false.
in_array($value, $array) - Returns true if the $value is defined in $array.

Here is a PHP script on how to use arrary_search():

$array = array("Perl", "PHP", "Java", "PHP");
print("Search 1: ".array_search("PHP",$array)."n");
print("Search 2: ".array_search("Perl",$array)."n");
print("Search 3: ".array_search("C#",$array)."n");
print("n");
?>

This script will print:
