In PHP, how does the order of function calls impact the accessibility of functions within other functions?

The order of function calls in PHP can impact the accessibility of functions within other functions if a function is called before it is defined. To solve this issue, you can define the functions before calling them in your code. This ensures that all functions are available when they are called. 

<?php

function bar() {
    echo "Inside bar function\n";
}

function foo() {
    echo "Inside foo function\n";
    bar();
}

foo();

?>
