PHP programming tips and tricks

Some notes on software development with PHP

Fake slow loading

$file = 'images/ad.jpg';
$type = 'image/jpeg';
header('Content-Type:'.$type);
header('Content-Length: ' . filesize($file));
sleep(12);
readfile($file);

PhpUnit, solving global variable problem

/*
 * phpunit keep everything global,
 * meaning that if you have two files that test for example stuff in subpages/
 * you will get an error since it tries to redefined the no_render function
 * 
 * So, this script is a workaround, it executes phpunit on one file at the time
 * and present the results
 */

$mo = find_all_files('.');

$failed=array();

Unit testing - SimpleTest

$test = new TestSuite('All file tests');

$dirs = array(
'classes/dir',
'connect',
'include',
'include/db',
'include/util',
'refactor/include'
);
global $configProd;
foreach ($dirs as $aDir) {
  foreach(glob('/php/unit/tests/'.$aDir.'/*Test.php') as $aFile) {

    if(! $configProd){
      echo "$aFile

";
    }
    $test->addFile($aFile);
  }
}

$test->run(new HtmlReporter());
