Are there any best practices for using printf() in PHP to avoid unexpected output?

When using printf() in PHP, it's important to ensure that the placeholders (%s, %d, etc.) match the number and type of variables passed to the function. Failure to do so can result in unexpected output or errors. To avoid this issue, always double-check the format string and the variables being passed to printf() to ensure they align correctly.

$name = "John";
$age = 30;

// Correct usage of printf with matching placeholders and variables
printf("My name is %s and I am %d years old.", $name, $age);
