To find the first element of an array in PHP, you can use the array_shift() function. This function shifts the first element off an array and returns it. Here's an example:
In this example, we have an array $myArray with three elements. We then use the array_shift() function to remove the first element ("apple") and assign it to a variable $firstElement. Finally, we echo out the value of $firstElement. The output will be "apple", which is the first element of the array.
It's important to note that using array_shift() modifies the original array by removing the first element. If you need to keep the original array intact, you can make a copy of it and work with the copy instead.
