PHP - (very) long loading with fopen - php

When using the fopen handle, loading times become drastically huge. About 10 seconds or so to be precise.
$handle = fopen("http://services.runescape.com/m=hiscore_oldschool/index_lite.ws?player={$pname}", "r");
if (FALSE === $handle) {
echo "Failed";
exit("Failed to open stream to URL");
}
$contents = '';
while (!feof($handle)) {
$contents .= fread($handle, 32);
}
Above is the code I am using.
Is this an inefficient way to do it? If so, what is the efficient way?
I also explode these results and print them. But even after removing the printing of the results part, the load times are unchanged.

Maybe you can speed it up if you use some other way to do the http request.
You can use cURL:
$url = "http://services.runescape.com/m=hiscore_oldschool/index_lite.ws?player={$pname}";
$c = curl_init();
curl_setopt($c, CURLOPT_URL, $url);
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt($c, CURLOPT_TIMEOUT, 10);
$contents = curl_exec($c);
curl_close($c);
Or try it via:
$contents = file_get_contents( "http://services.runescape.com/m=hiscore_oldschool/index_lite.ws?player={$pname}" );

curl multi download image

I would like if it's possible to optimize this request with multi curl handler ?
Thanks
$array_img = array(
'https://www.foooooobbbaaarrr.fr/images/1.jpeg',
'https://www.foooooobbbaaarrr.fr/images/2.jpeg',
'https://www.foooooobbbaaarrr.fr/images/3.jpeg',
'https://www.foooooobbbaaarrr.fr/images/4.jpeg');
foreach ($array_img as $k => $v)
{
$ch = curl_init($v);
$name = ($k + 1).'.jpeg';
$fp = fopen($name, 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
}
That's a very open-ended question, but with the PHP/CURL's multi functions you can at least get all those files in parallel instead of getting them in a serial manner.

Saving an image from a PHP URL using curl and PHP

I have tried to download an image from a PHP link. When I try the link in a browser it downloads the image. I enabled curl and I set “allow_url_fopen” to true. I’ve used the methods discussed here Saving image from PHP URL but it didn’t work. I've tried "file_get_contents" too, but it didn't work.
I made few changes, but still it doesn’t work. This is the code
$URL_path='http://…/index.php?r=Img/displaySavedImage&id=68';
$ch = curl_init ($URL_path);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$raw=curl_exec($ch);
curl_close ($ch);
$fp = fopen($path_tosave.'temp_ticket.jpg','wb');
fwrite($fp, $raw);
fclose($fp);
Do you have any idea to make it works? Please help. Thanks
<?php
if( ini_get('allow_url_fopen') ) {
//set the index url
$source = file_get_contents('http://…/index.php?r=Img/displaySavedImage&id=68');
$filestr = "temp_ticket.jpg";
$fp = fopen($filestr, 'wb');
if ($fp !== false) {
fwrite($fp, $source);
fclose($fp);
}
else {
// File could not be opened for writing
}
}
else {
// allow_url_fopen is disabled
// See here for more information:
// http://php.net/manual/en/filesystem.configuration.php#ini.allow-url-fopen
}
?>
This is what I used to save an image without an extension (dynamic image generated by server). Hope it works for you. Just make sure that the file path location is fully qualified and points to an image. As #ComFreek pointed out, you can use file_put_contents which is the equivalent to calling fopen(), fwrite() and fclose() successively to write data to a file. file_put_contents
You can use it as a function :
function getFile($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$tmp = curl_exec($ch);
curl_close($ch);
if ($tmp != false){
return $tmp;
}
}
And to call it :
$content = getFile(URL);
Or save its content to a file :
file_put_contents(PATH, getFile(URL));
You're missing a closing quote and semicolon on the first line:
$URL_path='http://…/index.php?r=Img/displaySavedImage&id=68';
Also, your URL is in $URL_path but you initialise cURL with $path_img which is undefined based on the code in the question.
Why use cURL when file_get_contents() does the job?
<?php
$img = 'http://…/index.php?r=Img/displaySavedImage&id=68';
$data = file_get_contents( $img );
file_put_contents( 'img.jpg', $data );
?>

File download from server times out

I have the following code timing out when I try to download some files from server
<?php
$ch = curl_init();
$source=array("landshop_formdata.sql","landshop_clientdata.sql","landshop_blogs.sql","landshop_counter.sql","landshop_hitems.sql");
$sourcepath = "http://www.landshoppe.com/";
$root = "C:\Program Files\EasyPHP-5.3.8.1\www\Landshoppe/Downloaded Dbs/";
foreach($source as $bkup){
$source=$sourcepath.$bkup;
curl_setopt($ch, CURLOPT_URL, $source);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec ($ch);
$destination = $root.$bkup;
$data = file_get_contents($source);
$file = fopen($destination, "w+");
fputs($file, $data);
fclose($file);
}
?>
What should be the problem ?
To avoid timeout issues, you can disable it by adding this line at the top of your server-side code :
set_time_limit(0); // no time limit
Or, you may set a timeout that is long enough to inform your user that something went wrong if nothing happend.

How to get a file from another server and rename it in PHP

I was looking for a way to perform a number of tasks in PHP
Get a file from another server
Change the file name and extention
Download the new file to the end user
I would prefer a method that acts as a proxy server type thing, but a file download would be fine
Thanks in advance
Try this
<?php
$url = 'http://www.example.com/a-large-file.zip';
$path = '/path-to-file/a-large-file.zip';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
file_put_contents($path, $data);
?>
After you save rename the file with whatever name you need
Refer this
http://www.php.net/manual/en/ref.curl.php
See the example at http://www.php.net/manual/en/function.curl-init.php
This grabs the data and outputs it straight to the browser, headers and all.
If you have allow_url_fopen set to true:
$url = 'http://example.com/image.php';
$img = '/my/folder/flower.gif';
file_put_contents($img, file_get_contents($url));
Else use cURL:
$ch = curl_init('http://example.com/image.php');
$fp = fopen('/my/folder/flower.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
I use something like this:
<?php
$url = 'http://www.some_url.com/some_file.zip';
$path = '/path-to-your-file/your_filename.your_ext';
function get_some_file($url, $path){
if(!file_exists ( $path )){
$fp = fopen($path, 'w+');
fwrite($fp, file_get_contents($url));
fclose($fp);
}
}
?>

Get JPG Dimensions from Partial Extract Without Writing to Disk

I wrote a PHP script that allows me to get the dimensions (width and height) of a remotely hosted JPG without having to download it in full (just the first 10K).
The problem with this is I write the partial download to a file, then read that file to extract the information I need (using getImageSize).
I know this can be down without writing to disk, but I do not know how.
Anyone have suggestions/solutions?
Here is my original code:
function remoteImage($url){
$ch = curl_init ($url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
curl_setopt($ch, CURLOPT_RANGE, "0-10240");
$fn = "partial.jpg";
$raw = curl_exec($ch);
$result = array();
if(file_exists($fn)){
unlink($fn);
}
if ($raw !== false) {
$status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($status == 200 || $status == 206) {
$result["w"] = 0;
$result["h"] = 0;
$fp = fopen($fn, 'x');
fwrite($fp, $raw);
fclose($fp);
$size = getImageSize($fn);
if ($size===false) {
// Cannot get file size information
} else {
// Return width and height
list($result["w"], $result["h"]) = $size;
}
}
}
curl_close ($ch);
return $result;
}
My original question, which lead to this, is here - and might be helpful.
It may be possible to use a memory file stream.
$fn = 'php://memory';
See: http://php.net/manual/en/wrappers.php.php
