PHP - I Know Its A Long Shot But Hey Anythings Worth Asking.
I am trying to get a website up for my mother and am running into so many brick walls. There is so much i dont know about php. I know basics. What i would really love is some to try to tutor me through what i need to know. If anyone could do this for me i would be forever grateful.
Similar TutorialsI would like to apply some addition functionality to a form which add news records into the database. Basicaly what i want is similar to what this forum does with the [ code ] [ /code ] but what i want for the user to be able to add [ quote ] [ /quote ] and when the post is viewed then that specific area of the acticle body will be formated diffrently. I hope this makes sence. Hey Folks This is a major long shot but is their a way that i can use php to upload one mp3 file and one doc file, then get the php script to place the mp3 file in one folder but also copy the mp3 file and make it into a zip file and place it into another folder as well as also make another copy of the mp3 file pair it with the doc file and make it into another zip file in yet another folder mp3->---------------------------->--mp3----------------->----mp3 into zip-------->--mp3 + doc into zip &---- > --Uploaded via php----->--placed in folder a--->----placed in folder b--->--placed in folder c doc-->---------------------------->--copied--------------->----mp3 copied--------->-- But thier is a catch the host i am using didn't activate ZipArchive() function so need a diferent way to make the zip file. Any Ideas people? because i have been pulling my hair out at this one please help Phil i made a little uploader class, its not refined but it works, here is the class <?php /* This is a simple file uploader class created by me: Hugo Johnson website: www.jwmstudios.com email: hugoj@hotmail.com Its my first real shot at creating a php class, i am still a todler to this. */ Class Uploader { // Declaring my variables needed for this class, it makes sense. public $input_field_name = "userfile"; // default input field name public $file_size =300000; // default file size public $path_directory = ""; // location to send the file public $action_path_and_file = "uploader.php"; // default form action function form() { // This form is optional used if no form is provided, only good for one file echo <<<END <form enctype="multipart/form-data" method="post" action="$this->action_path_and_file "> <input name="$this->input_field_name" type="file" /><br /><input type="hidden" name="max_size" value="$this->file_size" /> <input type="submit" value="Upload" /> </form> END; } function file_field($field_name) { // optional for adding more than one file echo "<br /><input name=\"$field_name\" type=\"file\" /><br />"; } function upload($input_field_name) { // this will upload a file that coresponds to a field name of type file $filename = $_FILES[$input_field_name]['name']; // coming from the form $filesize = $_FILES[$input_field_name]['size']; // " " $temp = $_FILES[$input_field_name]['tmp_name']; // " " // move Uploaded File function places the file from its temp directory and puts it into the desired directory, $path = $this->path_directory.$filename; // you can type a path directory structure between the quotes eg. ../ or /filestorage etc. $uploadfile = move_uploaded_file($temp, $path); // moving file from temp location to new chosen path echo $uploadfile === TRUE ?

I'm trying to learn static layouts, and I'm just getting the hang of them. A few friends are telling me to go responsive to accommodate mobile/tablet users? I can see it from a business sites perspective where you want all types of users and with ease of access, but my site is going to be a gaming modification community, where mobile users aren't really the target audience as it's quicker and easier to download them on the PC than a Phone. I was going to accommodate that audience by allowing them very basic usage (chat, forums, account) and leave off the heavy parts like the gallery, and downloads.
Am I going in the wrong direction? Should I be heading down the responsive route? I've literally only just started the first page for the site, but it'd mean re-learning a whole bunch more new stuff which'd prolong the sites progress.
Just looking for a little advice in which direction to head
So I've been using this websocket: http://code.google.com/p/phpwebsocket/
Love it because I don't know javascript as well as I do PHP. (Absolutely hated learning socket.io and their style of javascript, just gave up on it).
Anyways, I'm using MYSQL with the php socket for the chatroom authentication with my forum. (Sending the cookie values to the socket, to authenticate user). It's working fine and the MYSQL only get's called for each time a user is authenticated (logged into the websocket). The usernames and sessions are actually stored in a Temporary array which is nice. So only on authentication it queries the database for the authentication itself. (Very lightweight and a smart way for a chat system).
My question is, how does this compare to a node.js and socket.io server with a MYSQL plugin, etc? seems like that route would actually be more intensive?
I don't even need to include the socket.io.js for the client / PHP setup I have here as well. This way seems lightweight in my opinion (clientside) but not sure on the server end.
Thoughts?
TLDR: Running a PHP Websocket as compared to a node.js/socket.io server with mysql plugins the same in performance? Is it even noticeable? Should I be worried?
Edit: Disregard compatibility issues too. ( Using this http://tools.ietf.org/html/rfc6455 protocol is fine for my audience and intentions )
Edited by Monkuar, 02 December 2014 - 07:46 PM. I am using Amazon's S3 service to allow users to upload images. Since you have to pay for this service, my plan was to resize all uploaded images (maybe to a max of 200 pixels wide or something) immediately before sending them to Amazon. I googled this and only thing I found said that "resizing on the fly is slow and expensive because disk space is cheaper than CPU." Is this accurate? Anyone have any thoughts on this? I feel like I have to restrict the size of images some way because I don't wan't people uploading huge 2000x2000 images. In case it matters, below is some code I have used below for resizing (albeit on my own server), so I imagine I'll use something similar for this new project which ultimately sends the image to Amazon. Code: [Select] // This is the temporary file created by PHP $uploadedfile = $_FILES['userfile']['tmp_name']; // Create an Image from it so we can do the resize $src = imagecreatefromjpeg($uploadedfile); // Capture the original size of the uploaded image list($width,$height) = getimagesize($uploadedfile); $newheight=70; $newwidth= 70; $tmp=imagecreatetruecolor($newwidth,$newheight); // this line actually does the image resizing, copying from the original // image into the $tmp image imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height); // now write the resized image to disk. I have assumed that you want the // resized, uploaded image file to reside in the ./images subdirectory. $imagefolder = 'images/userimages/user' . $_SESSION['userid'] . '.jpg'; $filename = $imagefolder; $_SESSION['filename'] = $filename; if (imagejpeg($tmp,$imagefolder,100)) { $imagemessage = "File is valid, and was successfully uploaded into FOLDER.\n"; $success="yes"; } else { $imagemessage = "Possible file upload attack!\n"; $success="no"; } imagedestroy($src); imagedestroy($tmp); // NOTE: PHP will clean up the temp file it created when the request // has completed. } I have started learning OOP, by following a few tutorials, My problem with most tutorial is they show you how, but don't tell you the what and the why. It's all good an well seeing what to do, but if you have no idea why it's being done, you don't learn much. I started a tutorial on Udemy but am not actually gaining a lot from it. I want to alter the code so that it will do it the way I want it to. I am not wanting you to write the code for me, if you do please explain it so that I can understand the logic, preferably show me where to make changes and point me at the php tutorial that can solve my problem. I have been trying to solve this for a couple of weeks now, I tried a few things but none worked.

But that is not my main issue. I have a search going on: <?php $sql = "SELECT * FROM video WHERE MATCH(name,description,location,keywords) AGAINST('" . mysql_real_escape_string($_POST['searchfield']) . "' IN BOOLEAN MODE)"; ?> I have rows that contain either "fort worth" or "fort collins" for example. When I search "fort worth" it finds all the rows including the fort collins rows. That is expected as it contains "fort". The issue is "fort collins" is showing up before "fort worth" What can I do fix this? If I take out the "IN BOOLEAN MODE" part then it works, but breaks other parts of my search Hi All, I am trying to call a javascript pop-up window via a link by echoing out the html via php but keep getting parse errors: Parse error: syntax error, unexpected ')', expecting ',' or ';' Here is the code in question: Code: [Select] echo "<td class=\"today\"> <a href=\"javascript:statusWindow('status.php?month=".$month."&day=".$day."&year=$year');\">"$day_num</a> </td>\n"; And here is the javascript function: Code: [Select] <script type="text/javascript"> function statusWindow(url){ status_popupWin = window.open(url, 'status', 'resizable=yes, scrollbars=yes, toolbar=no,width=400,height=400'); status_popupWin.opener = self; } </script> Any help is appreciated. Thanks, kaiman Hello , I've this code its skip the weekend ,and I've a table for special events has field datetime. What I need when its come across this datetime skip it like it does with the weekend. there's the code Code: [Select] <?php$database_date = '2011-08-12, 07:00:00'; //this comes from your database, $updated_time = strtotime('+' . hoursLeft($database_date,7,16,24) .

I'm waiting for your replys.. I try to get how long my message was sent with this... $Now = strtotime ("now"); $dateEnvoi = $fetchDiscussion['dateEnvoi']; //my date from my DB $timeEnvoi = mktime($dateEnvoi); $TempsEnvoi = $dateNow - $dateEnvoi; and it try to get how long it was post ... same thing as on facebook... like the 26 minutes ago from FB how can i do it ? I'm working on a site that provides database results. To get to the final report, I'm going through a few pages where the user selects specific options. This builds up arrays that need to be passed from one page to another. As a result the final page has a pretty lengthy variable list. Since I want to provide a link to certain customers where they don't have to go through all the option select stuff, I'm using the GET method on the final page. Due to all the arrays I need to pass, I'm hitting hyperlink address character limitations, and I fear I will eventually hit browser URL length limits. Is there any way to provide links to customers without using the GET method so I could keep the URL length down? Guys, why the following mysql stored procedure taking much more time comparing with firebird one?

I've written a script thats going to take a really long time to execute... Whats the best way to do this as far as the server not timing out? My script is calculating some statistics based on other tables in the database and then storing them in another table. The results are going to be hundreds of thousands or maybe even millions of rows. I keep getting this error, because people can track their support tickets by using a MD5 encrypted code upon submitting, and I'm wondering if maybe it's too long? Code: [Select] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'by FROM replies WHERE replyto = 'c8c3455c5efadc80b05316c412ab61e6' ORDER BY id D' at line 1 Query: Code: [Select] $replies = mysql_query("SELECT message,by FROM replies WHERE replyto = '$id' ORDER BY id DESC") or die(mysql_error()); I have the following code on a page Code: [Select] <?PHP session_start();?> <HTML> <HEAD> <META http-equiv="Content-Type" content="text/html; charset=windows-1252"> <TITLE>Running Test Cricket</TITLE> </HEAD> <BODY> <?PHP echo "Time at start ".$_SERVER['REQUEST_TIME']; #This is our hourly updates for teams if it is due - it is set off by the variable 'teamUpdateTime' echo "<BR>1"; $updateTime=time(); #Get the current time and put it into the variable $teams = mysql_query("SELECT * FROM teams WHERE teamUpdateTime<'$updateTime'"); //Go through all the teams while($team = mysql_fetch_array($teams)) { echo "<BR>UPDATING - hourly - ".$team['name']; #Show the team we are updating include("../updates/hourly_update_team.php"); #Update all the teams that are due to be updated } echo "<BR>2"; mysql_close($sqldb); //Close the database echo "<BR>Time at end ".$_SERVER['REQUEST_TIME']; ?> </BODY></HTML>While the code is crude it is not for the public to see - it is for updating teams in an online game I am creating. What my problem is that the REQUEST_TIME at the start and end of the code are always outputted the same; the code is there to see how long the page takes to do. I sit there and count how long the page takes to activate (load, whatever the terminology is) and it can take up to 40 seconds - but the REQUEST_TIME tells me it takes 0 seconds so obviously something is wrong. My question is simple - how do I get this code to output the REQUEST_TIME when the code starts and when it finished, thus showing me how long it took for the page to load. I wish to do this to try and speed it up. James Hi I'm trying to figure out how to calculate how long since a datevariable I have stored is from whenever the page is loaded.. I currently have a stored datevariable in the format: YYYY-MM-DD H:m:s ... So basically what I wish to accomplish is figuring out whenever i load the page which has stored this variable, how much time has passed. I want it to show up as for example : '10 minutes ago'.. '1 hour 25minutes ago' if it's the same day.. if its more than 1 day old it's enough to show only the number of days.....'1week 3 days ago' etc etc |
