PHP regular extracts images from articles, and replaces and moves the image directory_PHP tutorial

This article will list some commonly used PHP regular rules to extract images from articles, and replace and move image directory codes. I hope this article will be helpful to everyone.

When uploading pictures, if not all the uploaded pictures are used, you can set it to only save it in a temporary folder when uploading. When the article is published, move the actually used pictures to a useful directory, so that regular cleaning is useless. Directory will do.

代码如下

复制代码

//转移临时文件夹中的图片     $imgssss = preg_match_all("/linshi/[^s'"]+.jpg|png|gif|jpeg{1}/ui",$content,$imgss);     $i=1;     foreach($imgss as $aimg){     if(is_string($aimg)){     if (file_exists($aimg)){     $newdir = "upload/".date("ymdhis")."/";     if (!file_exists($newdir)){     mkdir($newdir,0755,true);     }     $newname = $newdir.date("ymdhis").$i.".".pathinfo($aimg,PATHINFO_EXTENSION);     rename($aimg,$newname);     $content = str_replace($aimg,$newname, $content);     }     $i++;     }elseif(is_array($aimg)){     foreach($aimg as $imga){     if (file_exists($imga)){     $newdir = "upload/".date("ymdhis")."/";     if (!file_exists($newdir)){     mkdir($newdir,0755,true);     }     $newname = $newdir.date("ymdhis").$i.".".pathinfo($imga,PATHINFO_EXTENSION);     rename($imga,$newname);     $content = str_replace($imga,$newname, $content);     }     $i++;     }     }     }

If you just move a single image it is easier:

The code is as follows

代码如下	复制代码
$newdir = "upload/".date("ymdhis")."/"; if (!file_exists($newdir)){ mkdir($newdir,0755,true); } $newname = $newdir."s_".date("ymdhis").".".pathinfo($upimgurl,PATHINFO_EXTENSION); rename($upimgurl,$newname);

Copy code

$newdir = "upload/".date("ymdhis")."/";
if (!file_exists($newdir)){
mkdir($newdir,0755,true);
}
$newname = $newdir."s_".date("ymdhis").".".pathinfo($upimgurl,PATHINFO_EXTENSION);
rename($upimgurl,$newname);
