PHP capture a remote picture with image address in the content and save the method, _php tutorial

The method by which PHP collects remote images with image addresses in the content and saves them

In this paper, we describe the remote picture with image address in PHP collection and save the method. Share to everyone for your reference. The implementation method is as follows:

Copy CodeThe code is as follows: function my_file_get_contents ($url, $timeout =30) {
if (function_exists (' Curl_init '))
{
$ch = Curl_init ();
curl_setopt ($ch, Curlopt_url, $url);
curl_setopt ($ch, Curlopt_returntransfer, 1);
curl_setopt ($ch, Curlopt_connecttimeout, $timeout);
$file _contents = curl_exec ($ch);
Curl_close ($ch);
}
else if (ini_get (' allow_url_fopen ') = = 1 | | strtolower (ini_get (' allow_url_fopen ')) = = ' on ')
{
$file _contents = @file_get_contents ($url);
}
Else
{
$file _contents = ";
}
return $file _contents;
}

Copy CodeThe code is as follows: function Get_remote ($body, $title) {

$img _array = Array ();
$img _path = Realpath (".. /.. /.. /upfile/news/"). ' /'. Date ("y/m/d/"); Capture Remote picture Save address
Die ($img _path);
$img _rpath= '/upfile/news/'. Date ("y/m/d/"); Set Access Address
$body = Stripslashes (Strtolower ($body));
Preg_match_all ("/(SRC|SRC) =[" | ' |] {0,} (http://(. *). (gif|jpg|jpeg|png)) /isu ", $body, $img _array);
$img _array = Array_unique ($img _array[2]);
foreach ($img _array as $key = + $value) {
$get _file = my_file_get_contents ($value, 60);
$filetime = time ();
$filename = Date ("Ymdhis", $filetime). Rand (1,999). '. '. substr ($value, -3,3);
if (Emptyempty ($get _file)) {
@sleep (10);
$get _file = my_file_get_contents ($value, 30);
if (Emptyempty ($get _file)) {
$body = Preg_replace ("/". Addcslashes ($value, "/"). " /isu ", '/notfound.jpg ', $body);
Continue
}
}
if (!emptyempty ($get _file)) {
if (mkdirs ($img _path))
{
$fp = fopen ($img _path. $filename, "w");
if (fwrite ($fp, $get _file)) {
$body = Preg_replace ("/". Addcslashes ($value, "/"). " /isu ", $img _rpath. $filename, $body);
}
Fclose ($FP);
@sleep (6);
}
}

}
$body =str_replace ("Return $body;

}

function Mkdirs ($dir)
{
if (!is_dir ($dir)) {
if (!mkdirs (DirName ($dir))) {
return false;}
if (!mkdir ($dir, 0777)) {
return false;}
}
return true;
}
Use the following:

$str = ' FASFSDAFSA ';
Echo get_remote ($str, ' pictures ');
