小弟測試了一下，如何抓取字串中的文字功能，發現當用到陣列時，好像就無法判斷
請問該如何解決

<?php
 header("Content-Type:text/html; charset=UTF-8");
	 echo mb_strpos("老王喜歡哈哈笑abc，你說老蕭好笑不好笑1234","好",0,"UTF-8")+1;
	
	 echo '<hr>';
	
	$A="老王喜歡哈哈笑abc，你說老蕭好笑不好笑1234";
	$B="老";
	echo mb_strpos($A,$B,0,"UTF-8")+1;
	
	 echo '<hr>';
	
	$C=array("老王","喜歡","哈哈笑","你說","老蕭","好笑不好笑");
	$D="老";
	foreach ($C as $key=>$Value){
		if(mb_strpos($C[$key],$D,0,"UTF-8")>0)
				{echo "YES";
				 echo '<hr>';}
	
			else
				{echo "NG";
				echo '<hr>';}
	}
	
?>
