The simplest way of debugging is adding echo or die calls to your code.

Pros

Fast way to check simple issues

Cons

No environment information
Complex issues need lots of debugging code
No type information for echoed variables
Hard to display complete objects/arrays


<?php
function foo() {
    echo "Foo has been called!<br />";
}

function bar() {
    die("Bar has been called!<br />");
}

for ($i = 0; $i < 3; $i++)
    foo();

for ($i = 0; $i < 3; $i++)
    bar();
?>

Output

Foo has been called!
Foo has been called!
Foo has been called!
Bar has been called!
