本文实例讲述了php遍历类中包含的所有元素的方法。分享给大家供大家参考。具体分析如下:

这里可获得php类包含的所有元素以key-value的形式输出

class MyTestClass{
  const TESTVAR1 = 1001;
  const TESTVAR2 = 1002;
  const TESTSTR1 = 'hello';
}
$rc = new ReflectionClass('MyTestClass');
$v = $rc->getConstants(); 
asort($v);// sort by value
//ksort($v);// sort by key
foreach ( $v as $name => $value){
  echo "$name => $value\n";
}

运行结果如下:

TESTSTR1 => hello
TESTVAR1 => 1001
TESTVAR2 => 1002

希望本文所述对大家的php程序设计有所帮助。
