How can errors like "Function name must be a string" be resolved when working with PHP scripts?

The error "Function name must be a string" occurs when trying to call a function in PHP with a variable that is not a string. To resolve this, make sure that the function name being called is stored in a string variable before invoking the function. 

$functionName = 'myFunction'; // Store the function name in a string variable
$arg1 = 'argument1';
$arg2 = 'argument2';

if (function_exists($functionName)) {
    $functionName($arg1, $arg2); // Call the function using the variable
} else {
    echo "Function does not exist";
}

function myFunction($arg1, $arg2) {
    // Function implementation
}
