php中遍历二维数组的几种方式

<?php

//使用for循环遍历
$arr2=array(array("张三","20","男"),array("李四","25","男"),array("王五","19","女"),array("赵六","25","女"));
echo "<table border=2 bordercolor=red><tr><td>姓名</td><td>年龄</td& gt;<td>性别</td></tr>";
for($i=0;$i<4;$i++){
echo "<tr>";
for($j=0;$j<3;$j++){
   echo "<td>";
   echo $arr2[$i][$j];
   echo "</td>";
}
echo "</tr>";
echo "<br>";
}
echo "</table>";
?>

//使用foreach遍历

<?php
$arr = array("one"=>array("name"=>"张三","age"=>"23","sex"=>"男"),
    "two"=>array("name"=>"李四","age"=>"43","sex"=>"女"),
    "three"=>array("name"=>"王五","age"=>"32","sex"=>"男"),
    "four"=>array("name"=>"赵六","age"=>"12","sex"=>"女"));

foreach($arr as $k=>$val){
   echo $val["name"].$val["age"].$val["sex"]."<br>";
}
echo "<p>";
?>

<?php
$arr = array("one"=>array("name"=>"张三","age"=>"23","sex"=>"男"),
    "two"=>array("name"=>"李四","age"=>"43","sex"=>"女"),
    "three"=>array("name"=>"王五","age"=>"32","sex"=>"男"),
    "four"=>array("name"=>"赵六","age"=>"12","sex"=>"女"));
foreach($arr as $key=>$value){
foreach($value as $key2=>$value2){
   echo $value2;
}
echo "<br>";
}

?>
