Check If A Value Exists In An Array

This function checks if a value exists in an array. It uses PHP’s in_array function which checks if a value is in an array. If the value is found, it returns true, otherwise it returns false. This function is useful for checking if an array contains a certain value.

PHP Function:

function valueExists($arr, $value) { return in_array($value, $arr); }

// Example
echo valueExists([1, 2, 3, 4, 5], 3); // true
echo valueExists([1, 2, 3, 4, 5], 6); // false
