pdebugging php code example

Example 1: php best debugging functions

<?php
$myVar = "hello world!";

var_dump($myVar);
print_r($myVar);

$allVars = get_defined_vars();
print_r($allVars);
debug_zval_dump($allVars);

function sayHello($hello) {
    echo $hello;
    debug_print_backtrace();
}

sayHello($myVar);
?>

Example 2: php best debugging functions

I find it very useful to print out to the browsers console instead of just var_dumping:

function console_log( $data ){
  echo '<script>';
  echo 'console.log('. json_encode( $data ) .')';
  echo '</script>';
}

Usage:
$myvar = array(1,2,3);
console_log( $myvar ); // [1,2,3]
