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 used windows 10 as the operating system and I installed xampp it's been a long time and it chews well, until yesterday after an error in mysql.
So I looked for solutions on the internet and I finally solved the error by copying the files from C:\xampp\mysql\backup to C:\xampp\mysql\data.
then the service mysql is well marketed even as Apache.
PhpMyadmin chews well without a problem. phpmyadmin page shows, but my code, will not show.
The problem is: my old projects exist in htdocs only display "This page does not work" and "localhost" in the title head, and nothing loads from my project files.
Note: I used codeigniter as a framework.
Note: I can navigate to a new project but for existing projects beyond that it no longer works.
Thank you P.al
Use Directly like-
http://localhost/projects/form.html
Here your files should be inside C:\XAMPP\htdocs\Projects\yourfile.html
The error in your picture appear an php script error
Edit php.ini for display error and notice in browser
display_errors = on
save the php.ini restart apache and reload page.
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 was working on my magento page www.samsungtelefoonhoesjes.com and suddenly my homepage that normally works perfectly only shows everything until the home slider. after that everything is white....
The page worked 30 mins ago.
What is the best way to troubleshoot this?
Can I use firebug or something for this where should I start?
cleared cache
reindexed
removed cache
disabled the slider (this was my last change i did)
Firebug shows 500 Internal Server Error.
Try following solutions:
Check apache error_log, it should be in /var/log/apache2/error.log in most cases.
Check for permissions to your files and folders. Files should be 644 and folders should be 755. Reset permissions using magento cleanup script.
Check your .htaccess file.
Check out this article. http://techjam.gr/2012/magento/solve-magento-500-internal-server-errors/
Try restarting apache on the server, this worked for me.
I'm trying to get a file's content into a variable but I don't get anything when I read the file. I used both methods JFile::read() and file_get_contents() but both return the same thing: a blank string, not an error , not any boolean values or anything.
I want to mention that I'm working on a Linux machine (just for 2 days) and recently I changed the permissions for the entire machine to 777 ( I don't know if this affects something or not).
Is the a connection between my OS, permissions and the php's file_get_contents()? or Joomla restricts file reading?
Also I want to mention that my file_get_contents() function was added manually by me in the index.php file , also the file I want to read was manually added in the same folder with index.php.
We had the same problem with one of our clients, it turned out it was a firewall issue. It was very hard to debug this issue. I suggest you check with your networking team.
I am assuming, of course, that you have set the PHP error reporting level to the maximum and that you have checked the error logs.
It seemed the problem was from my system . I messed it up when I changed the permissions so I have to re-install it.
Never change the permissions on a Linux for the entire file system.
I've just installed LAMP on my Ubuntu 9.10 machine, and everything works fine except when I copy my PHP files from another computer.
The LAMP guides I've followed also made me create a phpinfo() test file, which works, but when I try to type in e.g. index.php absolutely nothing happens - just a blank page in FireFox. :(
The files are in the exact same directory.
I'm thinking it's probably something with permissions and so on, but since I'm new to both PHP and Ubuntu, I'm kind of lost. It's like I can't create a PHP file with my file browser, but only by using the terminal - like when I created the testing.php from the LAMP guide.
Whaddayaknow... I made an error, tried to:
echo "Hello" world
which, even though I'm a PHP noob, I clearly know is wrong.
I think I'll have to figure out how to enable some sort of error reporting, a blank page is clearly not good enough.
You mean you have a index.php (copied from another computer) and a test.php (edited by hand, with a call to phpinfo()) in the same apache directory, the second works from your browser and the first doesnt ?
That can be a permission issue, or some compilation error in your php.
About permissions, for files should be readable from the apache server (more precisely, form the user that runs the apache server). You can type chmod a+r index.php.
YOu can also check your apache error logs (location dependent on installation). In any case it's vital to know where the error logs are if your are developing a web site.
