Fonctions pratique pour debuguage
backtrace() peut-être utilisé un peut partout pour trouver ce qui ne va pas dans son code. Très utile lorsque l'on travaille en orienté objet.
1 <?php
2 // print_r avec joli formatage
3 function xdump($v) { echo '<pre>'; print_r($v); echo '</pre>'; }
4
5 // Même chose mais avec var_dump
6 function xvdump($v) { echo '<pre>'; var_dump($v); echo '</pre>'; }
7
8 // affiche un backtrace et meurt
9 function backtrace($err='') {
10 echo '<div id="err">';
11 if ($err != '') echo "<strong>Erreur : $err</strong><br/>\n";
12 echo "<strong>Traceback </strong>:<pre>";
13 foreach( debug_backtrace() as $v ) xdump( $v );
14 echo "</pre></div>";
15 die;
16 }
