下面介绍php中遍历关联数组的三种方法:
foreach 'good', 'swimming' => 'very well', 'running' => 'not good' ); foreach ($sports as $key => $value) { echo $key.: .$value.
;}?>
程序运行结果:
football: goodswimming: very wellrunning: not good
each 'good', 'swimming' => 'very well', 'running' => 'not good' ); while ($elem = each($sports)) { echo $elem['key'].: .$elem['value'].
;}?>
程序运行结果:
football: goodswimming: very wellrunning: not good
list & each 'good', 'swimming' => 'very well', 'running' => 'not good' ); while (list($key, $value) = each($sports)) { echo $key.: .$value.
;}?>
程序运行结果:
football: goodswimming: very wellrunning: not good
