This function returns the first element of an array. It uses PHP’s reset function which sets the internal pointer of an array to its first element and returns its value. This function is useful for getting the first item from an array without knowing its key or index.
PHP Function:
function firstElement($arr) { return reset($arr); }
// Example
echo firstElement([1, 2, 3, 4, 5]); // 1
echo firstElement(['a', 'b', 'c']); // 'a'
