Minifying JavaScript Effectively With Php - php

Hi everyone i have a Php function which use JSMin to Minify JavaScript but i want a regex to replace
long arguments name with a or b
function foo(long_arg_name, long_arg_name2){
alert(long_arg_name + long_arg_name);
}
to
function foo(a,b){
alert(a+b);
}

You can use this plugin:
https://github.com/promatik/PHP-JS-CSS-Minifier
It uses this minifier http://javascript-minifier.com/
Or use this script from
http://javascript-minifier.com/examples
<?php
// setup the URL, the JS and the form data
$url = 'http://javascript-minifier.com/raw';
$js = file_get_contents('./public/ready.js');
$data = array(
'input' => $js
);
// init the request, set some info, send it and finally close it
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$minified = curl_exec($ch);
curl_close($ch);
// output the $minified
echo $minified;
?>
Don't forget to cache everything :)

How send post request from php to python?

I want send post request from php to python and get answer
I write this script which the send post
$url = 'http://localhost:8080/cgi-bin/file.py';
$body = 'hello world';
$options = array('method'=>'POST',
'content'=>$body,
'header'=>'Content-type:application/x-ww-form-urlencoded');
$context = stream_context_create(array('http' => $options));
print file_get_contents($url, false,$context);
I'm use custom python server
from http.server import HTTPServer, CGIHTTPRequestHandler
server_address = ("", 8080)
httpd = HTTPServer(server_address, CGIHTTPRequestHandler)
httpd.serve_forever()
And python script which the takes post request
print('Content-type: text/html\n')
import cgi
form = cgi.FieldStorage()
text2 = form.getfirst("content", "empty")
print("<p>TEXT_2: {}</p>".format(text2))
And then I get
write() argument must be str, not bytes\r\n'
How can it be solved?
P.S Sorry for my bad english
Check curl extension for php http://php.net/manual/en/book.curl.php
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://localhost:8080/cgi-bin/file.py");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
"postvar1=value1&postvar2=value2&postvar3=value3");
// in real life you should use something like:
// curl_setopt($ch, CURLOPT_POSTFIELDS,
// http_build_query(array('postvar1' => 'value1')));
// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec ($ch);
curl_close ($ch);
You can also use a library like guzzle that may have some other bells and whistles you may want to use.
Example usage can be found on this other answer here:

replace php function 'file' using curl

how to replace php function 'file' using curl?
$ego_quote = file($egoUrl); nicely put into an array.
$ego_quote[0] = error=OK
$ego_quote[1] = eta=Overnight
$ego_quote[2] = price=56.44
how can i achieve this when i'm using CURL?
Reason, function 'fopen' which is related to function 'file' not available on our production server.
Thank you
Thanks to Crayon Violent in this post.
$ego_quote = explode("\n",$ego_quote);
Which will give you the same result as function file
$ego_quote[0] = error=OK
$ego_quote[1] = eta=Overnight
$ego_quote[2] = price=56.44
You could do something like this:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $egoUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
echo $output;

String replace data retrieved by curl

I have created a curl function that returns all the html on a page (along with cookies)
I want to strip out the information (will also be needing to remove scripts a links brought in)
Here is the code i have
<?php
/* gets the data from a URL */
function get_data($url) {
$ch = curl_init();
$timeout = 5;
$cookie_data =
implode(
"; ",
array_map(
function($k, $v) {
return "$k=$v";
},
array_keys($_COOKIE),
array_values($_COOKIE)
)
);
curl_setopt($ch, CURLOPT_COOKIE, $cookie_data);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
preg_replace('/<meta (.*) \/>/i','', $data);
return $data;
}
echo get_data('http://go.etracc.net/l/25492/2013-12-04/374rh');
}
?>
Any help would be awesome!
You can use strip_tags with second parameter specifying which all tags you wish to keep.
http://www.php.net/strip_tags
Example from the doc: to keep a and p tags
// Allow <p> and <a>
echo strip_tags($text, '<p><a>');

Get Final URL From Double Shortened URL (t.co -> bit.ly -> final)

I couldn't convert a double shortened URL to expanded URL successfully using the below function I got from here:
function doShortURLDecode($url) {
$ch = #curl_init($url);
#curl_setopt($ch, CURLOPT_HEADER, TRUE);
#curl_setopt($ch, CURLOPT_NOBODY, TRUE);
#curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
#curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = #curl_exec($ch);
preg_match('/Location: (.*)\n/', $response, $a);
if (!isset($a[1])) return $url;
return $a[1];
}
I got into trouble when the expanded URL I got was again a shortened URL, which has its expanded URL.
How do I get final expanded URL after it has run through both URL shortening services?
Since t.co uses HTML redirection through the use of JavaScript and/or a <meta> redirect we need to grab it's contents first. Then extract the bit.ly URL from it to perform a HTTP header request to get the final location. This method does not rely on cURL to be enabled on server and uses all native PHP5 functions:
Tested and working!
function large_url($url)
{
$data = file_get_contents($url); // t.co uses HTML redirection
$url = strtok(strstr($data, 'http://bit.ly/'), '"'); // grab bit.ly URL
stream_context_set_default(array('http' => array('method' => 'HEAD')));
$headers = get_headers($url, 1); // get HTTP headers
return (isset($headers['Location'])) // check if Location header set
? $headers['Location'] // return Location header value
: $url; // return bit.ly URL instead
}
// DEMO
$url = 'http://t.co/dd4b3kOz';
echo large_url($url);
Finally found a way to get the final url of a double shortened url. The best way is to use longurl api for it.
I am not sure if it is the correct way, but i am at last getting the output as the final url needed :)
Here's what i did:
<?php
function TextAfterTag($input, $tag)
{
$result = '';
$tagPos = strpos($input, $tag);
if (!($tagPos === false))
{
$length = strlen($input);
$substrLength = $length - $tagPos + 1;
$result = substr($input, $tagPos + 1, $substrLength);
}
return trim($result);
}
function expandUrlLongApi($url)
{
$format = 'json';
$api_query = "http://api.longurl.org/v2/expand?" .
"url={$url}&response-code=1&format={$format}";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $api_query );
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 0);
curl_setopt($ch, CURLOPT_HEADER, false);
$fileContents = curl_exec($ch);
curl_close($ch);
$s1=str_replace("{"," ","$fileContents");
$s2=str_replace("}"," ","$s1");
$s2=trim($s2);
$s3=array();
$s3=explode(",",$s2);
$s4=TextAfterTag($s3[0],(':'));
$s4=stripslashes($s4);
return $s4;
}
echo expandUrlLongApi('http://t.co/dd4b3kOz');
?>
The output i get is:
"http://changeordie.therepublik.net/?p=371#proliferation"
The above code works.
The code that #cryptic shared is also correct ,but i could not get the result on my server (maybe because of some configuration issue).
If anyone thinks that it could be done by some other way, please feel free to share it.
Perhaps you should just use CURLOPT_FOLLOWLOCATION = true and then determine the final URL you were directed to.
In case the problem is not a Javascript redirect as in t.co or a <META http-equiv="refresh"..., this is reslolving stackexchange URLs like https://stackoverflow.com/q/62317 fine:
public function doShortURLDecode($url) {
$ch = #curl_init($url);
#curl_setopt($ch, CURLOPT_HEADER, TRUE);
#curl_setopt($ch, CURLOPT_NOBODY, TRUE);
#curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
#curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = #curl_exec($ch);
$cleanresponse= preg_replace('/[^A-Za-z0-9\- _,.:\n\/]/', '', $response);
preg_match('/Location: (.*)[\n\r]/', $cleanresponse, $a);
if (!isset($a[1])) return $url;
return parse_url($url, PHP_URL_SCHEME).'://'.parse_url($url, PHP_URL_HOST).$a[1];
}
It cleans the response of any special characters, that can occur in the curl output before cuttoing out the result URL (I ran into this problem on a php7.3 server)

PHP Printing with Google Cloud Print

I am currently adding the ability to a php back-end system to allow it to print directly and I am trying to get things working with Google's Cloud Print. Imagine the app as an online shopping cart and I want it to print picking notes (completed orders) without the need for someone to login. The server is remote and the destination has Cloud Ready Printers.
So far I have been successful in getting it to print using the interfaces, as long as I am simply passing HTML, plain text or a URL to a PDF. I am able to set the print to color, marginless and the print quality.
However where I have hit a problem is, the PDF which the system creates are not publicly accessible, hence I can't pass a URL to the file, I need to pass the contents of the file.
I have been trying with no success to modify one of the examples I have found on the web HERE. However I don't know the language so am struggling with it.
Another example in python HERE again I have been trying without success!
I'm using PHP and the Zend framework to work with the interface. Here is one sample I have tried, cut down to where I am trying to prepare the file to send, like I say I'm not really sure on translating from python to php, or if the python script even works, but this is what I came up with:
<?php
// Test print a job:
$b64_pathname = PDF_PATH.'ec22c3.pdf'.'.b64';
$fileType = "application/pdf";
// Open the original file and base64 encode it:
$dataHandle = fopen(PDF_PATH.'ec22c3.pdf', "rb");
$dataContent = fread($dataHandle, filesize(PDF_PATH.'ec22ed167763a15e8591a3776f3c65c3.pdf'));
fclose($dataHandle);
$b64data = $fileType.base64_encode($dataContent);
// Store the base64 encoded file:
$ourFileHandle = fopen($b64_pathname, 'w');
fwrite($ourFileHandle, $b64data);
fclose($ourFileHandle);
// Read the contents of the base64 encoded file and delete it:
$fileHandle = fopen($b64_pathname, "rb");
$fileContent = fread($fileHandle, filesize($b64_pathname));
fclose($fileHandle);
unlink($b64_pathname);
// URL encode the file contents:
$file = urlencode($fileContent);
// Add the file and send to the printer:
$client->setParameterPost('content', $file);
$client->setParameterPost('contentType', $fileType);
$client->request(Zend_Http_Client::POST);
?>
Here's a method in php using cUrl (note, I have object level variables called _auth, _username, _password & _printerId).
First, build a function to post with cUrl:
function processRequest($url, $postFields, $referer) {
$ret = "";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_USERAGENT, "");
if(!is_null($postFields)) {
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
$postFields);
// http_build_query() will properly escape the fields and
// build a query string.
}
if(strlen($this->_auth) > 0) {
$headers = array(
"Authorization: GoogleLogin auth=". $this->_auth,
//"GData-Version: 3.0",
"X-CloudPrint-Proxy", "yourappname"
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_REFERER, $referer);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$ret = curl_exec ($ch);
curl_close ($ch);
return $ret;
}
Then, a function to authorize against Google:
public function authorize() {
$url = "https://www.google.com/accounts/ClientLogin";
$post = array("accountType" => "HOSTED_OR_GOOGLE",
"Email" => $this->_username,
"Passwd" => $this->_password,
"service" => "cloudprint",
"source" => "yourappname");
$resp = $this->processRequest($url, $post, "");
preg_match("/Auth=([a-z0-9_\-]+)/i", $resp, $matches);
$this->_auth = $matches[1];
}
Finally, build a function to submit to the cloud printer:
function printDocument($title, $docBytes)
{
$url = "http://www.google.com/cloudprint/submit?printerid=". $this->_printerId."&output=json";
$post = array(
"printerid" => $this->_printerId,
"capabilities" => "",
"contentType" => "dataUrl",
"title" => $title,
"content" => 'data:application/pdf;base64,'. base64_encode($docBytes)
);
$ret = $this->processRequest($url, $post, "");
echo $ret;
}
In use, call authorize() to get the authentication token. Then just read your file (from wherever) into a variable and pass it to printDocument with the title.
In order to send base64 encoded content you need to send another parameter in submit request:
$client->setParameterPost('contentTransferEncoding', 'base64');
