探讨php中遍历二维数组的几种方法详解

复制代码代码如下:
<？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
复制代码代码如下:
<？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>";
？>

复制代码代码如下:
<？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>";
}
