What potential issues or errors could arise when using the array_push function in PHP?

One potential issue that could arise when using the array_push function in PHP is if the variable passed to the function is not an array. This will result in a warning and the variable will not be treated as an array. To solve this, you should ensure that the variable being passed to array_push is indeed an array. 

// Check if the variable is an array before using array_push
if (is_array($myArray)) {
    array_push($myArray, $newElement);
} else {
    // Handle the case where $myArray is not an array
    echo "Error: $myArray is not an array.";
}
