How can we troubleshoot errors related to the array_push function in PHP when adding elements to an array?

When troubleshooting errors related to the array_push function in PHP, you should first check if the variable you are trying to push elements into is actually an array. If it is not, you may encounter errors. Additionally, make sure that the array variable is properly initialized before using array_push. Finally, ensure that the elements you are trying to add are correctly formatted and not causing any issues.

// Example of troubleshooting errors with array_push function
$myArray = []; // Initialize an empty array

// Check if $myArray is an array before using array_push
if (is_array($myArray)) {
    array_push($myArray, "element1", "element2", "element3");
    print_r($myArray); // Output the array to verify elements have been added
} else {
    echo "Error: $myArray is not an array.";
}
