1、php foreach()跳出本次或當(dāng)前循環(huán)與終止循環(huán)方法phpforeach()跳出本次或當(dāng)前循環(huán)與終止循環(huán)辦法php中用foreach()循環(huán)中，想要在循環(huán)的時(shí)候，當(dāng)滿足某個(gè)條件時(shí)，想復(fù)制代碼$arr=array(&39;a&39;,&39;b&39;,&39;c&39;,&39;d&39;,&39;e&39;);$html=&39;&39;foreach($arras$key=>$value)if($value=&39;b&39;)$html.=$value;contin
