The example in this article describes the method of collecting and saving remote images with image addresses in PHP content. Share it with everyone for your reference. The specific implementation method is as follows:

The 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);
}

function get_remote($body,$title){

$img_array = array();
$img_path = realpath("../../../upfile/news/").'/'.date("y/m/d/"); //Collect remote image storage address
//die($img_path);
$img_rpath='/upfile/news/'.date("y/m/d/"); //Set the 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;
}
//Usage is as follows:

$str ='fasfsdafsa';
echo get_remote($str,'picture');
