I am trying to import lot's of images into my database which is in my .csv file, but before importing i am trying to check if url of an image is valid or not by using 'getimagesize()' function in php.
When i use getimagesize() function to check url of an image is valid or not at that time my importing is working too slowly.
So is there any other way to check image URL and import speedly as well please suggest me, Thanks in advance
The fastest way to test a remote url is using CURL with the NOBODY flag enabled, if your server supports it.
function remoteFileExists( $url )
{
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL,$url );
curl_setopt( $ch, CURLOPT_NOBODY, 1 );
curl_setopt( $ch, CURLOPT_FAILONERROR, 1 );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
$output = ( curl_exec( $ch ) !== false );
curl_close( $ch );
return $output;
}

I want that my bot when I write /orario he answer me with a inline keyboard.
So.. I created an array for my keyboard in this way:
$tastierino_giorno = '[{"text":"Testo","callback_data":"StampaMessaggio"}]';
and in another function I write this:
function tastieraInline($chatid, $tastierino)
{
global $token;
$messaggio = "Scegli per che giorno inviare il messaggio:";
$tastiera = '&reply_markup={"inline_keyboard":
['.urlencode($tastierino).'],"resize_keyboard":true}';
$url = "https://api.telegram.org/$token/sendMessage?chat_id=$chatId&parse_mode=HTML&text=".urlencode($messaggio).$tastiera;
file_get_contents($url);
}
After this, with an if, I check if the users has write "/orario".
} elseif($message == "/orario"){
tastieraInline($chatid, $tastierino_giorno);
}
Now the problem is that it doesn't works... what's the problem?
Change
$tastiera = '&reply_markup={"inline_keyboard":
['.urlencode($tastierino).'],"resize_keyboard":true}';
to
$tastiera = '&reply_markup='.urlencode('{"inline_keyboard":
['.$tastierino.'],"resize_keyboard":true}');
you should URL encode the whole JSON data
You should pay attention to the result returned from your telegram calls. file_get_contents is great for getting something working quickly but doesn't return any error information.
You should use curl or a library like guzzle. An example for curl:
$ch = curl_init( $url );
if ( $ch == FALSE )
{
error_log( "Error initialising curl" );
return FALSE;
}
curl_setopt( $ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1 );
curl_setopt( $ch, CURLOPT_POST, 0 );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, 1 );
curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, 2 );
curl_setopt( $ch, CURLOPT_FORBID_REUSE, 1 );
// Set TCP timeout to 30 seconds
curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, 30 );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array( 'Connection: Close' ) );
$result = curl_exec( $ch );
$error = curl_errno( $ch );
$errorStr = curl_error( $ch );
curl_close( $ch );
if ( $error != 0 )
{
return array( $errorStr, $result );
}
return $result;
Guzzle is a lot simpler if you don't mind installing an additional library.
Hopefully this will get you the error string from your failed telegram calls.
Onto your actual issue. You should create json for the keyboard markup using json_encode rather than appending strings. http_build_query makes building URLs much easier.
I have a long list of URLs saved in excel and have a shell script to use with cURL to retrieve all URLs with errors, redirects, and/or connection timeout. I have never used cURL or shell. I need to use it on windows. So far I only know how to get to " C:\MyCurl>curl ". I have my shell script saved in a notepad. Can someone please tell me in specific detail what to do, including what the script and URLs should be saved as? It would be very helpful as I do not want to have to do each one manually and could be useful for many times in the future. Thank very much for your time.
I don't have enough details to answer your question about using a curl with a shell script on your local machine. But you may want to consider avoiding a shell altogether. PHP has a robust curl library. If you add the function below to your PHP script and call it with the URL as the parameter like:
$result = file_get_contents_curl( $url );
you will have code that's far more portable and scalable.
function file_get_contents_curl( $url ) {
$ch = curl_init();
curl_setopt( $ch, CURLOPT_AUTOREFERER, TRUE );
curl_setopt( $ch, CURLOPT_HEADER, 0 );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, TRUE );
$data = curl_exec( $ch );
if ( curl_errno( $ch ) <> FALSE ) {
return FALSE;
}
curl_close( $ch );
return $data;
}
I have and xml url from a supplier which generates xml content dynamically with php like;
http://www.example.com/outputxml/index.php?xml_service_id=161
This url is valid for a static ip so I gave him my websites hosting ip. Is there a way to open that url in browser with data scraping? Because My internet connection has no static ip.
Thank you.
I have tried below code;
$url = 'http://www.example.com/outputxml/index.php?xml_service_id=161?';
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $xml );
$result = curl_exec($ch);
curl_close($ch);
echo $result;
But it gave html format.
Save the content on your server with something like a wget and then serve it. Please notice that you are probably going to infringe the policy of the xml's author (I don't know the consequences or the policy itself, but you should be careful), so you might consider to at least add a .htacces authentication on your server's page, just to not make the xml public.
I have a job application form that contains a bunch of text inputs and two fields to upload files (resume and cover letter).
This form needs to post to a job board API endpoint but the request has to be proxied so the API key isn't seen in the post. This is working fine with just the text inputs but I can't figure out how to get the files to upload as well. Below is what I have so far, which only posts the text.
How do I need to go about uploading the files as well?
<?php
if ( $_POST ) {
// API key
$api_key = 'super_secret_key';
$url = "https://api.myjobboard.io/applications/";
$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_USERPWD, $api_key . ":" . '' );
curl_setopt( $ch, CURLOPT_POSTFIELDS, http_build_query( $_POST ) );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_HEADER, false );
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
$response = curl_exec( $ch );
echo $response;
} else {
echo '<p>Error: No post data.</p>';
}
?>
I have an issue with the facebook linter feature. I'm trying to clean the Facebook cache of one my URL, with a PHP curl query. As you can see here (Updating Objects), Facebook got an api for scrapping all the content of an URL and update URL Facebook meta. It's the same API used in the Facebook Debugger Tool.
If I use their debugger manually, there is no problem. My URL is correctly scrapped and all corrects meta are retrieved. But it's not the case with a php curl query.
Here my actual code :
$furl = 'https://graph.facebook.com';
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $furl );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_POST, true );
$params = array(
'id' => "http://www.gametrader-app.com/aTPVev",
'scrape' => true,
);
$data = http_build_query( $params );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $data );
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
$resultLinter = curl_exec( $ch );
The API result displays incorrect/old facebook meta.
Moreover, I have tried to call directly the URL of the Debugger without success
curl_setopt( $ch , CURLOPT_URL, "http://developers.facebook.com/tools/debug/og/object?q=http://www.example.com");
curl_setopt( $ch , CURLOPT_HEADER , 0 );
curl_setopt( $ch , CURLOPT_RETURNTRANSFER , true );
curl_setopt( $ch , CURLOPT_USERAGENT , $useragent );
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$str_response = curl_exec( $ch );
I need to do this for one reason. Here the full process :
Publish a new ad on the iPhone App "GameTrader"
Post an open graph on facebook for this publish
That's all ;)
If I don't clean the URL cache on Facebook side before the post open graph, I get this error :
Error during open graph : OAuthException: (#3502) Object at URL
http://www.gametrader-app.com/aTPVev has og:type of 'website'. The property 'ad' requires an object of og:type 'gametrader-app:ad'
Can you help to understand what I'm doing wrong ?
Cheers!
