php遍历二维数组的两种方法(转)

<?php
$erwei=array(array("广州","湖南","江西"),array("北京","上海","深圳"));
for($i=0;$i<=1;$i++){

for($j=0;$j<=2;$j++){
   echo $erwei[$i][$j];

}
echo "<br>";
}//for遍历
  
$erwei2=array("one"=>array("name"=>"张三","age"=>"21","sex"=>"男"),"two"=>array('name'=>"李四",'age'=>"20",'sex'=>"女"));
foreach ($erwei2 as $key=>$values){
foreach ($values as $key2=>$values2){
   echo $values2;
}
echo "<br>";
}//foreach遍历
?>
