PHP - Parsing Images From A Film - Question Of Speed
I am writing an OO PHP app to parse thousands of frames from a film, which will then each be manipulated and spat out using GD library funcs. Speed is of the essence.
To improve speed, I have considered: - Another language!? - Use of PHP Command Line Interface? ( Working with web browser is surely a slow affair?) If PHP was a standard R6 Yamaha available to Joe Public, what would I have to do to win a GP race - you know - change gearing, alter timing, change exhaust system, rip out the air filter What does the panel suggest? Thanks B Similar TutorialsIt seems like this is a question that may be on here already, but I couldn't find it with a search, so I apologize. I am given a string that represents a datetime, and it is always in this format: HH:mm:ss MMM DD, YYYY PDT. I just want to turn that into a proper format for mysql (Y-m-d H:i:s), but I'm not exactly sure how to go about that. (I could do this in C# rather quickly!) Probably a simple question, I hope someone can help! Thanks. Hey everyone, so im trying to utilize a systems OPTION command send prior to the POST command, the OPTION command will for example state that it would like to request specific headers. im trying to perform this to get the headers needed before the POST command im trying to execute, the values are required for the POST command i need to perform to get a response. The URL in question would be: https://media-entitlement.mlb.com/api/v3/jwt?os=windows&did=ffeae86c-9447-4bac-a021-caad0c02c605&appname=mlbtv_web Request method: OPTIONS (to get required headers):
Host: media-entitlement.mlb.com then a post command is performed just after which retrieves the values originally requested by the OPTIONS command prior to the POST:
Host: media-entitlement.mlb.com
Now Generally speaking, i fully understand their authorization etc. but this specific set of values seem only used in this one situation, they use bam-sdk which i understand pretty well. but needless to say this authorization bearer, and api-key value only seem generated via the initial OPTIONS grab in browser. so in summary i need to understand how these OPTIONS commands can be utilized to store the required headers as a variable which can be used in the POST command. Thanks in advance for your time and energy responding. mosb3rgler Edited June 14, 2019 by mosb3rglertypo I have this php page that based on what the user chooses shows them the appropriate photo galleria and i was wondering if their was any way i could speed this up this is the php code for selecting the galleria and I'm not showing the javascript that does the slide show because it s the galleriffic jquery plugin Code: [Select] <div id="Info"> <div id="page"> <div id="container"> <?php $g = mysql_real_escape_string($_GET['g']); $query = "SELECT * FROM pinkpanther_games WHERE Gallery_no = '$g'"; $results = mysql_query($query) or die("Query failed ($_query) - " . mysql_error()); $row = mysql_fetch_assoc($results); echo "<h1>" . $row['Day_Played'] .

Example: class test { function a(){ $obj = new DB_TableObject(); //blabla bla $this->b($obj); } function b($object){ $object->getResults(); } } class test { function a(){ $obj = new DB_TableObject(); //blabla bla $this->b($obj); } function b(){ $obj = new DB_TableObject(); $object->getResults(); } } Which one is better? The first or the second solution? Im going to use a large array of arrays, each of one having a lot of values and some sub arrays. My question is... is faster to use arrays or is better to have a object to acces using methods and all? i suppose objects are slower... Also i was planing in use arrays with string keys in nearly all places, normally these are slower, but in php hashes and arrays are the same tipe so i dont know... I'm using copy() to copy an image to a different directory. The problem is the image could be in 1 of 3 folders. With out knowing which folder its in how can I do this? Hello there, I'm very new to PHP and I need some help (please!) Basically I'm writing an actionscript application and I am using a php file to save an image to the server, the problem is I define a name in actionscript before I send the information to the php and it continuously saves over the same file.. Ideally I would like to attach the (jpg) image to an email, send the mail and delete the image ready for a new image to be created.. is this possible ? At least, I would like to add a +1 to each filename to stop the file being saved over continuously ! Thanks in advance for any help <?php $fileName = $_GET['filename']; $fp = fopen( $fileName, 'wb' ); fwrite( $fp, $GLOBALS['HTTP_RAW_POST_DATA'] ); fclose( $fp ); ?> this is pretty decent right? Code: [Select] mySQL_array SPEED TEST - [ 30,000 Numbers ] - SERIALIZED with BASE64 ENCODING AND GZ COMPRESSION 52.8KiB WRITE ARRAY in: 0.15 seconds. 52.8KiB READ ARRAY in: 0.03 seconds. 52.8KiB ROUND TRIP in: 0.18 seconds. (approx: 3.41 milliseconds per KiB) --- running on FIREFOX + EASY PHP 5.3.8.0 - ON ASUS G51VX - 2GHz dual core (x64) - 4GB RAM --- When pulling exif data from an image I have pretty much everythiung nailed down except for the Shutter Speed value. When pulled from the image this is returned as:- 'Shutter' => string '0.0015625' Now I know that the actual shutter speed at the time of shooting was 1/640 sec; does anyone have any ideas about how one would convert... 'Shutter' => string '0.0015625' to 1/640 sec... I have been scratching my head over this problem for a few days now and am stiull no wiser Since I got my websocket PHP server running nicely with my MYSQL, I can now have some fun
Attack speed is very simple, but I need your help with the unixtimestamp.
For example, There is a field name called "last_attack" and each time a user attacks a mob and a skill was performed; it will be updated with:
time();Then I disable the attack button for 2 seconds client side, but I also check that value against time() serverside as well. Now let's say the user's attack speed is 1.30% I want to make that Attack Speed check, to check it dynamically. It should now check only if the attack was less than 1.7 seconds ago instead of 2 seconds. How do I split up the unixtimestamp to work with percents? Edited by Monkuar, 03 December 2014 - 02:11 PM. Are there any codes or php scripts that will calculate the user's internet speed? Complete beginner here so just really looking for pointers on where to start. Been doing a bit of bug fixing on one of our sites because the past 3 programmers we've hired have disappeared on us. The big issue I'm looking to solve is the load time of a search. Our website (Love-Rugs) is taking about 6 or 7 seconds to perform a blank search (basically a quick browse) whereas out other site (Little-Persia) takes about a second. It wouldn't be so bad if it was just the initial search but going from one page (only 10 products listed per page) to the next takes the same amount of time. There seems to be an awful lot of queries (around 130-150) on the searches - however - when using some of the search options e.g. type and fabric to refine the search the queries actually stay high but the time to process the results is reduced significantly. I don't really understand why if the queries are still high the search time is much lower unless it's to do with the number of results returned. However this does not explain why Little-Persia (which has far more products on it) takes less time as there would obviously be more results. I realize that without code this isn't easy to answer so I'm just looking to see if someone can point me in the right direction to look at just now. I am currently using PHP 5.3.2 on IIS 7 and I am wondering how can I write a download script with resume and speed limit. After looking for a while, I found this script that works on speed limit: Code: [Select] <?php $local_file = 'file.zip'; $download_file = 'name.zip'; // set the download rate limit (=> 20,5 kb/s) $download_rate = 20.5; if(file_exists($local_file) && is_file($local_file)) { header('Cache-control: private'); header('Content-Type: application/octet-stream'); header('Content-Length: '.filesize($local_file)); header('Content-Disposition: filename='.$download_file); flush(); $file = fopen($local_file, "r"); while(!feof($file)) { // send the current file part to the browser print fread($file, round($download_rate * 1024)); // flush the content to the browser flush(); // sleep one second sleep(1); } fclose($file);} else { die('Error: The file '.$local_file.' does not exist!'); } ?> Though there is a big problem that the download file comes without extension. For example if the original file is file.ext then the client will receive it as file without any extension. I just want to use octet-stream since I have no interest in streaming or other things, but I really want the client to have the extension also. So could you please tell me what is wrong with the above script, and please show me a way to do resume download. Thank you very much for your help. Is there any php function I can test how fast my server is performing, like how fast its carrying out a certain action so I can see its resource usage. Iv'e been looking in to methods of scraping data from pages and has found several examples of using multi-curl to achieve this. But i am not used to curl and is not completely sure how it works and i need to find the fastest reliable (i do need all, or close to all, pages every run) method of getting the content of a number of pages (about 160). Here is an example i got from searching the web which i managed to implement: <?php /** * *@param $picsArr Array [0]=> [url], *@$picsArr Array will filled with the image data ， you can use the data as you want or just save it in the next step. **/ function getAllPics(&$picsArr){ if(count($picsArr)<=0) return false; $hArr = array();//handle array foreach($picsArr as $k=>$pic){ $h = curl_init(); curl_setopt($h,CURLOPT_URL,$pic['url']); curl_setopt($h,CURLOPT_HEADER,0); curl_setopt($h,CURLOPT_RETURNTRANSFER,1);//return the image value array_push($hArr,$h); } $mh = curl_multi_init(); foreach($hArr as $k => $h) curl_multi_add_handle($mh,$h); $running = null; do{ curl_multi_exec($mh,$running); }while($running > 0); // get the result and save it in the result ARRAY foreach($hArr as $k => $h){ $picsArr[$k]['data'] = curl_multi_getcontent($h); } //close all the connections foreach($hArr as $k => $h){ $info = curl_getinfo($h); preg_match("/^image\/(.*)$/",$info['content_type'],$matches); echo $tail = $matches[1]; curl_multi_remove_handle($mh,$h); } curl_multi_close($mh); return true; } ?> Since time is critical in my script i would ask if you think this is a good implementation or if you can point me in the direction of one that will save me noticeable run-time. Hello once again, i got this code that takes all images from a folder and displays them close to each other. Heres the code: <?php $dir = 'uploads/thumbs/watermarkedthumbs/'; $file_display = array ('jpg', 'jpeg', 'png', 'gif'); if (file_exists($dir) == false) { echo 'tt'; } else { $dir_contents = scandir($dir); foreach ($dir_contents as $file) { $file_type = strtolower(end(explode('.', $file))); if ($file !== '.' && $file !== '..' && in_array($file_type, $file_display) == true) { echo '<img src="', $dir, '/', $file, '" alt="', $file, '" />'; } } } ?> How do i add margins in between them? i wanna make it smth like 'margin-left:10px, margin-top-10px'. Also, how do i add an 'overflow'? i mean, my images currently are displayed in a div, and i wanna make it so that if the folder has lets say 9 images, it would only display 6 of them, and the rest would be displayed in the same div after i click a button or smth (like '1' for the first div and '2' would appear if theres an overflow, and when i click '2' the rest of the images would appear). To make these adjustments do i need to make a different php file or do i change something in this code? thanks in advance. Okay I have a function that stores data into an Array. The function takes about 7 seconds to run and through a number of different loops it creates one final array with about 15,000 keys. I want to recall this data a number of times in different functions, however how can I have this data easily accessible without running the function each time. EX: Code: [Select] function theFunction() { for($x=0;$x,=15000;$x++) { //Run the loop and store data. $string[$x] = //output from other loops and calculations } return $string } //Then later on if I want to recall the data the only way I know how is to do the follow: $newstring = theFunction() The only problem I have with this is that it has to re-run the function every time in order to get to the data it spits out. How can I store this data into another array outside of the function without having to re-run it? I hope this makes sense. Thanks. hello dear community, i am currently wroking on a approach to parse some sites that contain datas on Foundations in Switzerland with some details like goals, contact-E-Mail and the like,,, See http://www.foundationfinder.ch/ which has a dataset of 790 foundations. All the data are free to use - with no limitations copyrights on it. I have tried it with PHP Simple HTML DOM Parser - but , i have seen that it is difficult to get all necessary data -that is needed to get it up and running. Who is wanting to jump in and help in creating this scraper/parser. I love to hear from you. Please help me - to get up to speed with this approach? regards Dilbertone I have a table called "playlists", and a table called "musics". In the musics table, there is a column playlist_id which references the playlist that each music is contained.
I'm using api calls to display information on the site with JavaScript, so I need to return a JSON.
I need the json with the following structu
[
Playlists: [
{
Name: "etc",
musics: [
{
name: "teste.mp3" }, { name: "test2.mp3" } ] }, ... ] ] And this is my code: $query = $con->prepare("SELECT * FROM playlists WHERE user_id = :id"); Hello,
I try to get website speed of some website, but i can read only ''domain.com'' i can't read website files like css , js ... why ? i use proxies for this job.
here is the php code:
$options = array(
'useragent' => "Firefox (+http://www.firefox.org)", // who am i
'connecttimeout' => 120, // timeout on connect
'timeout' => 120, // timeout on response
'redirect' => 10, // stop after 10 redirects
'referer' => "http://www.google.com",
'proxyhost' =>'85.25.8.14:80'
);
$response = http_get("http://solve-ict.com/wp-content/themes/ict%20theme/js/jquery-1.7.1.min.js", $options , $info);
but it works fine with http://domain.com/ , but with files css or js it gives 404, using some free proxy servers available
?
Thanks.
