探讨php中遍历二维数组的几种方法详解

<?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>";
?>
