<?php$arr = array('a' => '0a0','b' => '0b0','c' => '0c0','d' => '0d0','e' => '0e0',);//********break********////用来跳出目前执行的循环，并不再继续执行循环了。 foreach($arr as $k => $v){if($k == 'c'){ break;}$arr2[$k] = $v;}var_dump($arr2);/*array (size=2)  'a' => string '0a0' (length=3)  'b' => string '0b0' (length=3)*///********continue********////立即停止目前执行循环，并回到循环的条件判断处，继续下一个循环。 foreach($arr as $k => $v){if($k == 'c'){ //忽略对这一项的处理continue;}$arr3[$k] = $v;}var_dump($arr3);/*array (size=4)  'a' => string '0a0' (length=3)  'b' => string '0b0' (length=3)  'd' => string '0d0' (length=3)  'e' => string '0e0' (length=3)*/?>
