What are some common reasons for receiving a fatal error when calling a function in PHP scripts?

Common reasons for receiving a fatal error when calling a function in PHP scripts include misspelling the function name, not including the file where the function is defined, or passing the wrong number of arguments to the function. To solve this issue, make sure the function name is spelled correctly, include the file where the function is defined using require or include, and ensure the correct number of arguments are passed to the function.

// Example code snippet to fix fatal error when calling a function
<?php
// Include the file where the function is defined
require 'functions.php';

// Call the function with the correct number of arguments
$result = myFunction($arg1, $arg2);
?>
