PHP - Http 500 Error
I am learning PHP using the book "Beginning PHP and MySQL 5 - From Novice to Professional", and I have come across a lesson in the book which I am stuck on.
The lesson is on using the echo() statement. I've typed in the following code and saved it as a php file.... <?php $heavyweight = "Lennox Lewis"; $lightweight = "Floyd Mayweather"; echo &heavyweight, " and ", $lightweight, " are great fighters."; ?> My Apache and PHP is working fine as my other PHP files work properly. When I try and view the file it says... "The website encountered an error while retrieving http://localhost:8888/phpdocs/multiplestringsecho.php. It may be down for maintenance or configured incorrectly." and when I click on more information it says... "HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request." Any ideas? Have I done something wrong? Any help would be much appreciated. Similar TutorialsTrying to run a simple program that, when submitted, stores the username and password as cookies. When clicking Submit, I get the error "HTTP Error 405 - The HTTP verb used to access this page is not allowed". If the username and password fields are left blank when submitting it's suppose to give a message to enter a username and password, but, I still get that error message.

I have seen a lot of resolutions online for example: 1) Copying the "php5isapi.dll" file to the PHP directory & under "Program Files" as well. 2) Copying the "favicon.ico" file etc etc Before I could elaborate the issue, please note that I am a Windows user - Windows XP (I know its not the best of the OS's to work with!!!) When initially I started getting the issue, I checked the "error.log" file under "C:\Program Files\Apache Software Foundation\Apache2.2\logs" & following is what I saw: ----------------------- [Sun Sep 18 14:13:25 2011] [notice] Server built: Sep 9 2011 10:26:10 [Sun Sep 18 14:13:25 2011] [notice] Parent: Created child process 4420 [Sun Sep 18 14:13:25 2011] [notice] Child 4420: Child process is running [Sun Sep 18 14:13:25 2011] [notice] Child 4420: Acquired the start mutex.

Many thanks in advance! Rahul This topic has been moved to Apache HTTP Server. http://www.phpfreaks.com/forums/index.php?topic=355524.0 I have no idea why it's doing it.

I am coding Arduino micro controller, and intended to GET the data from server MySQL db through php to turn ON/OFF LED. I could able to GET the data from manually updated MySQL db value, even I could able to successfully change the data of MySQL db from micro controller POST method. But I am getting error when trying to change the MySQL db value from browser using online POST tool, Following is PHP code at server
8 $api_key_value ="XXXXXXXXX";//Sample
9 $api_key ="";
10 $status = "";
11 $id ="";
12
13 if ($_SERVER["REQUEST_METHOD"] == "POST") {
14 $api_key = test_input($_POST["api_key"]);
15 if($api_key == $api_key_value) {
$id = test_input($_POST["id"]);
$status = test_input($_POST["status"]);
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection

Post Command: http://url/MySQL_POST.php?api_key=XXXXXXXXX&id=1&status=on Response/Error: Notice: Undefined index: api_key in <PATH>/MySQL_POST.php on line 14 Wrong API Key provided. Could be a basic issue, but I am very new to php coding and cannot solve this problem yet. Could someone please help? Thanks. As the title above says im trying to use this code: Code: [Select] require_once("http://www.example.com/connect_file.php"); its giving this error: Warning: mysql_query() [function.mysql-query]: Access denied for user 'username'@'localhost' (using password: NO) in /template/header.php on line 56 if i was to just use this code it works fine: Code: [Select] require_once("./connect_file.php"); Just incase it makes a difference, im testing this on index.php, however the codes above are not inside index.php, instead they are inside my /templates/header.php file which is included at the top of index.php any ideas? How do I only redirect the page when index.php is present? I am trying to build an app which will scan a site multple times, the only problem is the 403 error, how do I get around this. Searching seems to imply curl or user_agent, but can't get it working. Any suggestions? Thanks Not sure if this is possible. What I am trying to do is remove a section of text a user posts. ie: go to this url: http://url.com or http://this.domain.org I already have it to strip they <a href="whatever but not sure if I can do the other. Any help would be appreciated. Thanks i have been searching for a solution for about a day already. can anyone help me on how to use the http functions (if thats what it is called) in php? http://www.php.net/manual/en/book.http.php like for example. i need to use the http_get() function but it returns Fatal error: Call to undefined function.. in the manual it says that i need to put php_http.dll on the ext dir and enable it in php ini like this.. extension=php_http.dll ..which i already did im working under.. windows xp sp3 php 5.3.1 thanks guys Just a quick question. I'm using the Live HTTP Headers add-on for Firefox that display all the HTTP headers etc. I'm writing an article on it and want to include a screenshot of it in action. Are there any headers that I should hide from the reader for security reasons? Thanks for any help. Hi. I am trying to extract the main url from a string.
For example.
I want to extract:
"http://google.com" from "http://google.com/search/pic.jpg"
"https://secure.co.uk" from "https://secure.co.uk/secure/secure.gif"
I am able to do this with this code, where $url is the url:
preg_match("http://(.*?)/", $url, $matches);
preg_match("https://(.*?)/", $url, $matches);
Is there away to consolidate this into one regex search? Or am I being picky?
Thanks!
Hi, I don't know very much about php. I don't know any at all, actually. I play a game called Roblox where you get to use the programming languange, "Lua" to script your own games. What I am requesting has been done before on this game, but I only know Lua. I was also told PHP cURL is needed. Anyways, let me get to the point. I am essentially trying to create a system on my webserver (You can send HTTP Requests to external sites in this game via script) that will essentially log into an account on Roblox, to perform a task. My current idea would be to have the Lua script send a request to my webserver with an generated code that would access the username and password of my roblox account (Which would be on the webserver). It would then perform a task. Is this a good way to go about this? If not, I am open to suggestions. If you can find the time to actually help me set this up on my webserver, I would greatly appreciate it! I'm also sorry if this is the wrong place for this post, I'm new here. Hi Guys,
Total PHP Noob here. I’ve run into a brick-wall and would appreciate some words of wisdom. I can do this with a browser: http://86.60.161.24 // will echo hello World I can’t do this with my server: <?php $url = 'http://86.60.161.24'; $contents = file_get_contents($url); echo ($contents); ?> It looks like the server-side HTTP -request never “touches” my Arduino-chip. No network activity detected. Obviously there is going to be a lot more data transfer happening but I need to solve this issue first. Is there anything I can do to make this work? Any and all input greatly appreciated. Cheers!!
I have been using curl and curl_multi, but it takes about 500ms between each query. I am sending for example https://www.apidomain.com/user=test&pass=test It then should return an output of successful or unsuccessful. How can I do this to run the url in a loop of 10 iterations, without curl, but with the speed of a millisecond or less? Thanks! I have a hardware device that I can send commands to by typing in a URL in the address bar. One command tells me if the ports are in use: Code: [Select] http://admin:12345678@192.168.1.10/Set.cmd?CMD=GetPower It returns the result: Code: [Select] p61=1,p62=1,p63=1,p64=1 What I want to do is try and grab the result with PHP when the page loads so I can tell people if the port is turned on or off. So "p61=1" means port 1 is turned ON. If "p61=0" was displayed, it means port 1 is turned OFF. I am not sure if it is even possible to grab the information using PHP or not. Any place to start would be great! Thanks! Hello! I'm trying to understand exactly how http requests relate to a php script. 1) What would be considered a large amount? 2) How can I see how many I have for a given page? Thank you, Eric It seems to me that this should be easy, but I can't find it in the manual or the on the web, and the values in $_SERVER don't suggest anything. Context: script A loads script B using HTTPS. Now script B has to load resources (images, style sheets, etc). Browsers often object to HTTP references from a script run by an HTTPS request, so script B should generate URLs that use HTTPS. Thus it has to know that it was loaded with HTTPS. I can do this by brute force if I have to (defining a "protocol" constant in the script itself), but I'd rather make the test automatic. <?php //user name and Password for authentication $username = 'username'; $password = 'password'; if(!isset($_SERVER['PHP_AUTH_USER']) || !isset($_SERVER['PHP_AUTH_PW']) || ($_SERVER['PHP_AUTH_USER'] != $username) || ($_SERVER['PHP_AUTH_PW'] != $password)) { //The username/password are incorrect or haven't been entered so send the authentication headers header ('HTTP/1.1 401 Unauthorized'); header ('WWW-Authenticate: Basic realm= "Gator Boats" '); exit ('<h2>Gator Boats Admin</h2> Sorry, You ust enter a valid username and password ' . 'access this page.'); } ?> Every time I enter the User Name: username and Password: password it just resends the headers. Can you see what I am doing wrong? |
