Using in_array() function
To check if a value is exists in array or not, we can use the built-in in_array() function in PHP.
The in_array() function takes two arguments, the first argument is search value, the second argument is array itself and it returns true if a value is found in array; otherwise it returns false.
Here is an example:
$cars = array("Audi", "BMW", "Benz");;if (in_array("BMW", $cars)) { echo "value is found";}else{ echo "value is not found";}Output:
"value is found"
False case example:
$cars = array("Audi", "BMW", "Benz");;if (in_array("ford", $cars)) { echo "value is found";}else{ echo "value is not found";}Output:
"value is not found"
In the above example, we have passed the search value “ford” which is not available in $cars arrayso it returns output value is not found.
