这个数组如何用for循环出来

WBOYOriginal: 2016-06-23 13:39:421107browse

记住，前提必须是for循环，不要别的方法循环，切记！
Array
(
    [0] => /dgcms/d/file/product/yysj/gdjcpt/2015-02-15/50e9c339938f7f013cc1170a321f6458.jpg::::::/dgcms/d/file/product/yysj/gdjcpt/2015-02-15/50e9c339938f7f013cc1170a321f6458.jpg::::::
    [1] => /dgcms/d/file/product/yysj/gdjcpt/2015-02-15/71d522fdc9305d0d6f4cc6735e8035c4.jpg::::::/dgcms/d/file/product/yysj/gdjcpt/2015-02-15/71d522fdc9305d0d6f4cc6735e8035c4.jpg::::::
    [2] => /dgcms/d/file/product/yysj/gdjcpt/2015-02-15/50700eff01cc0fd13fdbfe8cc0863222.jpg::::::/dgcms/d/file/product/yysj/gdjcpt/2015-02-15/50700eff01cc0fd13fdbfe8cc0863222.jpg::::::
)
我只想循环出这个二维数组中的每一组数组中的第一个，

??是一???。

估?你是要??效果。

具体到实际问题
为啥我也是这样写的，只能输出一个图片呢

<?phpif($bqr['morepic']){$morepic=$bqr['morepic'];$rexp="rn";$fexp="::::::";$rr=explode($rexp,$morepic);$count=count($rr);$morpic="";for($i=0;$i<$count;$i++){$j=$i+1;$fr=explode($fexp,$rr[$i]);$smallpic=$fr[0]; //小图$bigpic=$fr[1]; //大图             $morpic .="<li class='active'><i></i><img  src='".$smallpic."'    style="max-width:90%"  style="max-width:90%" alt="这个数组如何用for循环出来" ><b></b></li>";              }                          echo $morpic;}?>

$rexp="rn";

你的$rexp="rn"; 是$rexp="\r\n"; 吗？用rn分割，你确定图片地址中不会出现 rn？
