Here we use the regular expression of PHP to implement:
| The code is as follows |
Copy Code |
$content = ' Here is the content of the article, insert here a picture test ';
$content = Stripslashes ($content);
$img _array = Array ();
Match all remote pictures
Preg_match_all ("/(src| SRC) =["| ' |] {0,} (http://(. *). (gif|jpg|jpeg|bmp|png)) /isu ", $content, $img _array);
Matching the Not duplicate picture
$img _array = Array_unique ($img _array [2]);
Print_r ($img _array); |
It matches the remote picture, and we need to keep it local. Here are two points to note:
1. Picture save path (Picture storage directory)
2. Actual access to picture address
Here is the complete example: (You can save to the local server to modify the appropriate place for testing)
| The code is as follows |
Copy Code |
| <! DOCTYPE html>
<meta charset= "UTF-8" >
<title>php Save the remote picture to the local, PHP will match the picture address in the article </title>
<body>
<?php
Save the remote picture in the article to the local
Author: yanue;
File Save directory path (please replace it with your own path, you can echo it)
$save _path = $_server [' Document_root ']. ' swfupload/attached/';
File Save Directory URL
$save _url = '/swfupload/attached/';
$save _path = Realpath ($save _path). '/';
Picture Storage Directory
$imgPath = $save _path. Date ("Ymd");
$IMGURL = $save _url. Date ("Ymd"); Create a folder
if (! Is_dir ($imgPath)) {
@mkdir ($imgPath, 0777);
}
$content = ' Here is the content of the article, insert here a picture test ';
$content = Stripslashes ($content);
$img _array = Array ();
Match all remote pictures
Preg_match_all ("/(src| SRC) =["| ' |] {0,} (http://(. *). (gif|jpg|jpeg|bmp|png)) /isu ", $content, $img _array);
Matching the Not duplicate picture
$img _array = Array_unique ($img _array [2]);
Print_r ($img _array);
Unlimited time
Set_time_limit (0);
foreach ($img _array as $key => $value) {
$value = Trim ($value);
Reading remote Pictures
$get _file = @file_get_contents ($value);
Save to local picture name
$imgname = Date ("Ymdhis"). '_' . RAND (10000, 99999). "." . SUBSTR ($value,-3, 3);
The actual file address (including path and name) saved to the local
$fileName = $imgPath. '/' . $imgname;
The address that is actually accessed
$fileurl = $imgUrl. "/" . $imgname;
File Write
if ($get _file) {
$fp = @fopen ($fileName, "w");
@fwrite ($fp, $get _file);
@fclose ($FP);
}
Replace the original picture address
$content = Ereg_replace ($value, $fileurl, $content);
}
Echo $content;
?>
</body>
