PHP Gets the remote picture and saves it to the local

Example 1

The code is as follows

Copy Code

/* * Function: PHP a variety of ways to achieve the perfect download remote pictures saved to local * Parameters: File URL, save file name, use the download method * Use the original name of the remote file when the save file name is empty */ function GetImage ($url, $filename = ', $type =0) { if ($url = = ") {return false;} if ($filename = = ") { $ext =strrchr ($url, '. '); if ($ext!= '. gif ' && $ext!= '. jpg ') {return false;} $filename =time (). $ext; } File Save path if ($type) { $ch =curl_init (); $timeout = 5; curl_setopt ($ch, Curlopt_url, $url); curl_setopt ($ch, curlopt_returntransfer,1); curl_setopt ($ch, Curlopt_connecttimeout, $timeout); $img =curl_exec ($ch); Curl_close ($ch); }else{ Ob_start (); ReadFile ($url); $img =ob_get_contents (); Ob_end_clean (); } $size =strlen ($IMG); File size $FP 2= @fopen ($filename, ' a '); Fwrite ($fp 2, $img); Fclose ($fp 2); return $filename; }

Example 2

The code is as follows

Copy Code

<?php // Function: Gets the remote picture and saves it to the local // // Determine if you have permission to write files to the local server // // Variable Description: $url is the full URL address of the remote picture and cannot be empty. $filename is an optional variable: If NULL, local file names are based on time and date Automatically generated. function Grabimage ($url, $filename = "") { if ($url = = ""): return false;endif; if ($filename = = "") { $ext =STRRCHR ($url, "."); if ($ext!= ". gif" && $ext!= ". jpg"): return false;endif; $filename =date ("Dmyhis"). $ext; } Ob_start (); ReadFile ($url); $img = Ob_get_contents (); Ob_end_clean (); $size = strlen ($img); $FP 2= @fopen ($filename, "a"); Fwrite ($fp 2, $img); Fclose ($fp 2); return $filename; } $img =grabimage ("Http://www.111cn.net", ""); if ($img): Echo ' <pre></pre> Else:echo "false"; endif; ?>

In the DEDECMS:

The code is as follows

Copy Code

if (!empty ($saveremoteimg)) { $body = Stripslashes ($body); $img _array = Array (); Preg_match_all ("/(src| SRC) =["| ' |] {0,} (http://(. *). (gif|jpg|jpeg|bmp|png)) /isu ", $body, $img _array); $img _array = Array_unique ($img _array[2]); Set_time_limit (0); $IMGURL = $img _dir. " /". Strftime ("%y%m%d ", Time ()); $imgPath = $base _dir. $imgUrl; $milliSecond = strftime ("%h%m%s", Time ()); if (!is_dir ($imgPath)) @mkdir ($imgPath, 0777); foreach ($img _array as $key => $value) { $value = Trim ($value); $get _file = @file_get_contents ($value); $rndFileName = $imgPath. " /". $milliSecond. $key.". substr ($value, -3,3); $fileurl = $imgUrl.

Example 4

The code is as follows

Copy Code

<?php // /Function: Get the remote picture and save it to the local // // //Make sure you have permission to write the file to the local server // // //Variable Description: //$url remote Map The full URL address of the slice, cannot be empty.
