How can you check if there are any error messages present in the nested array in PHP before proceeding with database insertion?

To check if there are any error messages present in a nested array in PHP before proceeding with database insertion, you can recursively search through the array to look for any error messages. This can be done by using a function that checks each element of the array, and if an error message is found, stop the process and handle the error accordingly. 

function checkForErrors($array) {
    foreach ($array as $key => $value) {
        if (is_array($value)) {
            checkForErrors($value);
        } else {
            if (strpos($value, 'error') !== false) {
                // Handle error message found
                echo "Error message found: $value";
                return;
            }
        }
    }
}

// Example nested array
$array = array(
    "user" => "John",
    "data" => array(
        "status" => "success",
        "message" => "An error occurred"
    )
);

checkForErrors($array);
