How can PHP developers ensure that a mailer function is called multiple times within a loop?

To ensure that a mailer function is called multiple times within a loop, PHP developers can include the mailer function inside the loop and iterate through the loop as needed. This will allow the mailer function to be executed multiple times based on the loop conditions.

// Sample loop to call mailer function multiple times
for ($i = 0; $i < 5; $i++) {
    // Call mailer function here
    mailerFunction();
}

// Sample mailer function
function mailerFunction() {
    // Function implementation to send email
    // This can include setting up the email content, recipient, etc.
}
