How can PHP developers troubleshoot issues related to array_push?

When troubleshooting issues related to array_push in PHP, developers should check if the variable being passed to array_push is actually an array. If the variable is not an array, it will result in an error. To solve this, developers can initialize an empty array if the variable is not already an array. 

// Check if $array is an array before using array_push
if (!is_array($array)) {
    $array = array(); // Initialize an empty array
}

array_push($array, $value); // Push $value into $array
