I got a weired behavior on my apache, php setup on debian system.
I tried to create an image with php and output it directly. It failed permanent and the browser said sth. like corrupt image file. After a lot of try and error arroun 3 hours I figured out that there is a TAB character added right at the beginning ob my image content, that does not belong there.
To proove that its part of the apache-php setup I created a test.php file, that just contains the letter 'a' and coppied this file to test.html. So Both files just contain the letter a.
You can see the resulting tab here:
http://www.activeroom.net/test.php
http://www.activeroom.net/test.html
and even on the base url itself - its a php-file, too.
Hope anybody can point me in the correct direction. Btw. on the console everything is fine: php test.php just returns an a. Maybe it is something about the Apache MimeTypes or headers?!
How stupid - there was a php-file prepended through the php.ini. That file had a tab at the end. Sometimes things are really messed up.

I currently have wampserver running and I'm trying to do live preview of a php file using Brackets.io. However when I click live preview I'm getting
Project settings for: Getting Started
Live preview base URL: ______________
I'm following this tutorial on running PHP scripts.
My php file is in C:/wamp/wwww/php_proj1/php1.php so I've been trying to put this in my "Base URL"
http://localhost/php_proj1/php1.php
However everytime when I type that and enter it, it just asks me for the "Live Preview Base URL" again and nothing happens. I also tried putting the URL in my 'File->Project settings' and that also didn't work. I'm just running a basic php script that echos some words.
It works when I manually type
http://localhost/php_proj1/php1.php
in my Chrome URL but not when I use Bracets live preview.
What am I missing or doing wrong? Do I need to config anything in my wampserver? I've just started learning php and using wampserver so I'm not entirely sure what I'm doing wrong.
Thanks!
EDIT: I'm following these 2 tutorials on doing this and it's just not working for me.
tutorial 1 and tutorial 2
EDIT2: Found my mistake.. I did not do File->Open Folder to open the folder that I was working on... Thanks to everyone that helped me with this, I will definitely not make this mistake again. sigh
The Live Preview Base Url should be set to the same url that you would use to launch your project in a browser.
So if you have a project in C:/wamp/wwww/php_proj1/ you would launch that project in a browser by entering http://localhost/php_proj1/php1.php therefore that is what Brackets is expecting to be entered into the Base Url field minus the actual script file name.
Remember the DocumentRoot of localhost is pointing to the folder C:/wamp/www/
So enter
http://localhost/php_proj1/
into the dialog that requests the Base Url.
Assuming you are editing the file php1.php at the time you clicked the Live Preview icon that is the script that will be run in the browser.
Oh and of course you have to have WAMPServer and therefore Apache up and running when you do this as it is running the code through Apache so that the PHP code can be interpreted.
Found my mistake. I did not do File->Open Folder to open the folder that I was working on...
Try the same thing but with a simple HTML file.
Try launching your project with PHP's built-in server. Open a terminal/cmd window and go to the folder php_proj1. Now execute php -S localhost:8000. Now set your Live preview path to http://localhost:8000/. If this one does work, then there may be a problem with Wamp.
Now remember that no matter what, you're not supposed to contain a file in the Live Preview path, but only a folder path. When you contain it, you get to this URL: http://server/file.php/file.php (double) and that's not exactly what you want...
If none of these work - there may be a problem with either your computer, Brackets, Chrome, or both. Try to reinstall them (Brackets first).
My two cents, is the name of the project php_proj1 ? If not you'll have to use http://localhost/ as your base URL.
Also (When you are using Brackets) check the content of the Chrome Network tab. F12 Developer Tools -> Network -> Filter -> Documents
Try to investigate the URLs, probably that'll give you some insight
I have a weird problem I cannot seem to solve (as a php noob).
I am working on simple php site (no sql involved). Everything was working perfectly till the moment I decided to copy over the files and edit them on another computer. All worked fine on the other computer as well. Then I took the files and copied them to the first computer again. Here came the problem: if I try to open ANY file copied from the second computer, it doesn't show anything, just a blank page. Even if the file was not edited at all on the second computer.
For example my index.php:
1. Copied from comp 1 to comp 2, no edits done
2. Copied from comp 2 to comp 1
3. Opened in the browser -> blank page
What's going on here and how to solve it? Is it some cache that apache is keeping? How to clear it? Both computers with OSX, however the second one was running MAMP, while the first had php/apache/sql set up.
Your permissions need to be set up correctly. Do the following:
Change the owner of the group to your user
chmod 0755 all the directories
chmod 0644 all the files
Then you are good to go!
You need to make sure that your permissions are set up correctly.
Apache Permissions
The blank page is displaying because Apache is encountering a PHP error somewhere, but is not set to display PHP errors.
Check out what is going on in your Apache error log and work from there. You could also look in the Developer Tools of a browser like Chrome, or use Firebug, to see what response your browser is getting from the server (most likely a HTTP 500 error).
I wouldn't recommend blindly changing ownership on files and directories until you know what is going on.
I am working on Wordpress.
After upload my project file in the live server and then for any certain changes, I found everything inside "styles.css" files comes into only one line.
Even what ever inside the "header.php" or "footer.php" also comes into only one line.
Then its become hardest to search any particular keyword.
Can anybody please suggest me, how do I prevent this kinda editing in the server?
I am using "NetBean 7" as the editor.
Your server has converted your file types to match the server's file system it sounds like. Your line breaks might be gone. Try opening them in Notepad++ or vim to be sure.
If you look at it in Windows under Wordpad it should work too.
I have an index.html in my wampserver www directory. On this html, there is a link for a user to upload file. When I hit the link, I select files to upload but instead of the uploadmanager.php which i have tested in my eclipse debugg environment to work, it displays the some part of the code on the web page without doing anything thing. This is not what I expect. Can someone please tell me what is wrong? Thank you.
sound like you are using php-short-open-tags (<? instead of <?php) without enabling this in your php.ini. change your php.ini or use the standart open-tags to solve this.
Are you sure you enabled PHP in WAMP?
Try creating a new uploadmanager.php file directly in wamp/www (or whatever subdirectory) and paste the code from your tested uploadmanager script into the new file. Then try to run it in WAMP.
I think it is a permissions problem. I copied an index.php file into a c:/wamp/www/subdirectory and it only displayed the code. Once I created a new index.php file and pasted the contents of the old file into it, it worked perfectly.
Are you posting to the uploadmanager.php page? Are you getting an error or just seeing the code? Can you post the code from the index.html page that handled the form and the part of the php code you're seeing for us to look at?
Every now and then I have Apache serving the .php as downloadable files instead processing them on the server, but only with random requests.
Some reasons, why this might happen, are
PHP misconfiguration
PHP-files in a directory without execute rights
wrong content type sent
timeout from script execution
In my situation the last bullet is the most dangerous, but luckily it seems to show up only immediately after modifying some of the .php files. I haven't tracked the problem any deeper yet, but it seems to relate some filesystem level operations (as the disk I/O is a bottleneck) and presents itself only in testing env.
I'm working with a custom made Joomla script that generates an image from a blob in a database. However, when we moved it from an Apache server to an IIS server, the script is breaking.
Upon investigation, it seems that now, there is a line break that is getting appended before the header function is being run (when I comment out the image portion, and do an echo "test";, test gets printed on line 2 of the source code.
I've gone through the script over and over again, and through the many files in the component, and can't seem to find out where this new line is coming from. At all.
I've tried using ob_start() and many similar functions, but nothing seems to work.
I'm completely out of ideas, and don't know where to turn.
Is there a way to trace what files are being called in the page, perhaps? Any thoughts on further steps?
Look out for additional whitespace at the end of PHP files. If a PHP file ends in more than a single return after the last ?>, that stuff gets printed regardless of where the file is/was included. That is a common error source in larger PHP projects and would meet your symptoms.
(To circumvent this, some have started with a coding standard that prohibits the last ?> in their source files, which is perfectly legal PHP.)
Be careful, maybe it's an encoding problem. Open the file with vim under linux to see if there an ^M or something like that.
