Debug some PHP code

debug.php

<?php
/**
 * Debug some piece of code
 * 
 * @method debug
 * @param  Variable|Function $code The code that you want to check
 * @param  Boolen            $die  Should the rest of the code on the page be prevented from executing
 */
function debug( $code, $die = true ) {
  printf( '<pre>%s</pre>', print_r( $code, true ) );

  if ( $die ) {
    die;
  }
}

/**
 * Usage
 */
$something = [ 1, "stuff",  ["key" => "value" ] ];

// Debug
debug( $something );

// Debug, but let the rest of the code on the page run
debug( $something, false );

This is just a quick solution and suitable in most situations. If more information is needed just use var_dump()
