小编给大家分享一下PHP循环遍历数组的方法有哪些,希望大家阅读完这篇文章之后都有所收获,下面让我们一起去探讨吧!
一、foreach():foreach()是一个用来遍历数组中数据的最简单有效的方法。
$colors = array("red","green","blue","yellow"); foreach($colors as $value){ echo "The color is $value <br>"; } #输出内容 /** The color is red The color is green The color is blue The color is yellow **/
二、for():使用for语句循环遍历数组,数组必须是索引数组。
$colors = array("red","green","blue","yellow"); for($i=0; $i<count($colors); $i++){ $value= $colors[$i]; echo "The color is $value <br>"; } #输出内容 /** The color is red The color is green The color is blue The color is yellow **/
三、while()和list(),each()配合使用:
$colors = array("red","green","blue","yellow"); while(list($key,$value) = each($colors)){ echo "The color is $value <br>"; } #输出内容 /** The color is red The color is green The color is blue The color is yellow **/
