How can one check if a specific array element in PHP has a value?

To check if a specific array element in PHP has a value, you can use the `isset()` function which determines if a variable is set and is not NULL. This function can be used to check if a specific array element exists and has a value assigned to it. 

// Example array
$array = array("a" => 1, "b" => 2, "c" => 3);

// Check if array element 'b' has a value
if(isset($array['b'])) {
    echo "Element 'b' has a value: " . $array['b'];
} else {
    echo "Element 'b' does not have a value";
}
