PHP中用foreach()循环中,想要在循环的时候,当满足某个条件时,想要跳出本次循环继续执行下次循环,或者满足某个条件的时候,终止foreach()循环,分别会用到:continue 与 break  

<?php
$arr= array(&#39;le&#39;,&#39;yang&#39;,&#39;jun&#39;,&#39;lecode&#39;,&#39;gagade&#39;);  
$html= &#39;&#39;;  
foreach($arras $key => $value){  
    if($value==&#39;b&#39;){  
        $html.= $value;  
        continue;// 当 $value为b时,跳出本次循环  
    }  
    if($value==&#39;c&#39;){  
        $html.= $value;  
        break;// 当 $value为c时,终止循环  
    }  
    $html.= $value;  
}  
echo$html; // 输出: abc
