thinkphp5.0 the path in the queried data table is the backslash that causes the picture to not display properly?

The path that is added to the picture in the datasheet can sometimes be a backslash, which causes the path to be recognized after the URL is written (although the path is recognized after the SRC), so you need to replace the backslash in the path with a forward slash, and the code is as follows:

1 $datu= Db::query (' Select images from think_ad where ad_position_id = 22 ');2     $str= "";3     foreach($datu  as $v)4     {5         $str.=implode($v);6         $str.= "|";7             8     }9     $str=substr($str, 0,strlen($str)-1);Ten     $str=Str_replace(‘\\‘,‘/‘,$str); One     $str=Explode("|",$str); A     $this->assign (' Datu ',$str);
