What function checks if an element exists in an array?in_arrayarray_filterexists_in_arrayarray_find
Solution
The function that checks if an element exists in an array is in_array in PHP. Here is how you can use it:
$array = array('apple', 'banana', 'cherry');
if (in_array('banana', $array)) {
echo "Banana is in the array";
} else {
echo "Banana is not in the array";
}
In this example, 'banana' is the element we are checking for in the array. The in_array function will return true if 'banana' is in the array, and false otherwise.
