PHP save image from url
Written by Codes Tips on March 22, 2009 – 2:11 pm -Download Source Code
You can save image from url in PHP you should first get thesource of the image from the url and after that save image to your server or disk depending on where you execute the php script.
First for getting an image from url you can use three ways to do this:
1. Using file_get_contents
$contents= file_get_contents('http://mydomain.com/folder/image.jpg');
2. Using fsockopen() function
To fetch an image with fsockopen() You should specify the host name of the server and the the rest or the url where the image is stored. To understand better here is a sample function, that takes the that returns the source code of the image:
function GetImg($host,$link) { $fp = fsockopen($host, 80, $errno, $errstr, 30); if (!$fp) { echo "$errstr (error number $errno) \n"; } else { $out = "GET $link HTTP/1.1\r\n"; $out .= "Host: $host\r\n"; $out .= "Connection: Close\r\n\r\n"; $out .= "Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5\r\n"; $out .= "Accept-Language: en-us,en;q=0.5\r\n"; $out .= "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7\r\n"; $out .= "Keep-Alive: 300\r\n"; $out .= "\r\n"; fwrite($fp, $out); $contents=''; while (!feof($fp)) { $contents.= fgets($fp, 1024); } fclose($fp); return $contents; } }
Example call:
$sourceimg=GetImg("www.mywebsiteexample.com","/image.jpg"); $sourceimg=strchr($sourceimg,"\r\n\r\n");//removes headers $sourceimg=ltrim($sourceimg);//remove whitespaces from begin of the string
3.Using CURL
function GetImageFromUrl($link) { $ch = curl_init(); curl_setopt($ch, CURLOPT_POST, 0); curl_setopt($ch,CURLOPT_URL,$link); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $result=curl_exec($ch); curl_close($ch); return $result; }
You should have installed at least PHP 4.0.2. and libcurl installed to use curl.
Here is a function that will get the source of the image into a string variable:
You can use this code to call the function to get the source of the image:
$sourcecode=GetImageFromUrl("http://domain.com/path/image.jpg");
After getting the image from url you should save image from url, doing a simple save to file from a string variable.
You can use this piece of code:
$savefile = fopen('/home/path/image.jpg', 'w'); fwrite($savefile, $sourcecode); fclose($savefile);

I’m using this script with a mysql backend, but it’s only saving the image name - no contents (0kb). Any idea what I’m doing wrong?
[code]
function GetImageFromUrl($link)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch,CURLOPT_URL,$link);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, curlOPT_BINARYTRANSFER,1);
$result=curl_exec($ch);
curl_close($ch);
return $result;
}
mysql_connect(”localhost”, “admin”, “password”) or die(mysql_error());
mysql_select_db(”database”) or die(mysql_error());
// Get all the data from the “example” table
$result = mysql_query(”SELECT * FROM table LIMIT 10″)
or die(mysql_error());
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
$path = “ftp://ftp.ftpserver.com”;
$sku = $row['product_sku'] . “.jpg”;
$img = $path.”/”.$sku;
$sourcecode=GetImageFromUrl($img);
$savefile = fopen(”/home/product/$sku”, ‘w’);
fwrite($savefile, $sourcecode);
fclose($savefile);
}

Hi,
You should use the property CURLOPT_UPLOAD in order to upload to http://ftp. This code is grabbing from a http page.
