Collect remote website images from a php utility instance and save them to the local device-PHP source code

Ec (2); the php utility instance collects remote website images and saves them locally. First, all & lt; img... & gt; use the regular expression. $ message & nbsp; article content & nbsp; regular (this is not yet) & nbsp; $ reg & quot; & lt; img [^ & gt;] * src & quot ;((. + )(. +) script ec (2); script

Collect remote website images from php instances and save them to your local device
First, extract all the regular expressions from the article. $ message // article content

// Regular (this is not yet)

$ Reg = "/] * src =" (http: // (. +)/(. +). (jpg | gif | bmp | bnp en) "/isU ";

// Store the extracted img address in the $ img_array variable.

Preg_match_all ($ reg, $ message, $ img_array, PREG_PATTERN_ORDER );

// Filter duplicate Images

$ Img_array = array_unique ($ img_array [1]);

Step 2. loop through the $ img_array. Save the image and replace foreach ($ img_array as $ img ){

// Determine whether it is an image on your website

If ('xxx. com '! = Get_domain ($ img) {// if this image is not on your server

// Read image files

$ Gimg = new GetImage ();

$ Gimg-> source = $ img;

$ Gimg-> save_to = './data/temp /';

$ FILE = $ Gimg-> download (); // move the image to the local device.

// Save the image to the position where the image is saved.

$ Img_path = pic_save ($ FILE, 0 ,'');

// Text path replacement

$ Message = str_replace ($ img, $ img_path, $ message );

}

}

... At this time, the image in $ message has been replaced with the local address of your server, and the image is saved to your server.
