I am very new to PHP. I am currently working on a project. When I was running XAMPP there was a port that was blocked. That stopped me from being able to use the MySQL database. After moving to port 3307 I try to connect to the database, and I am getting the following error message.
Parse error: syntax error, unexpected token "echo", expecting
"function" or "const" in C:\Users\17204\OneDrive\Desktop\Evecash
Ticketing System\Xampp\htdocs\mainfolder\db.php on line 9
Once again, I am new to PHP. If anyone can help me thanks.
I tried to change the port back to 3306 and also double checked how that tables were set up in the MySql database

I am a newbie to YII.
I have a project which is divided into different modules. I have copy pasted one module from one system into mine and I'm unable to open that new module
It shows the following error-
Alias "invmgmt.InvmgmtModule" is invalid. Make sure it points to an existing PHP file and the file is readable.
I have also included this module in my main.php file.
you must include it in 'modules' part of yii config file:
config path is:
protected/config/main.php

I am not able to run my project as I am getting these :
**Warning: require(C:\xampp\htdocs\test-project/protected/config/main.php): failed to open stream: No such file or directory in C:\xampp\htdocs\test-project\framework\base\CApplication.php on line 133
Fatal error: require(): Failed opening required 'C:\xampp\htdocs\test-project/protected/config/main.php' (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\test-project\framework\base\CApplication.php on line 133**
notice the forward and back slashes in your path.
C:\xampp\htdocs\test-project/protected/config/main.php
for windows always use backslashes or use the PHP pre-defined constant DIRECTORY_SEPARATOR.

I've searched on the Internet about this error. Somebody told me that my computer is missing lib xml for php. But I don't know how to install it on Ubuntu 12.04 TLS.
PHP Fatal error: Call to undefined function uft8_decode()
The function name is utf8_decode(), not uFT8_decode().
var_dump(function_exists('utf8_decode')); should tell you if it's available. If this returns bool(false), then php-xml package is probably missing in your PHP installation. Make sure it is installed. If it isn't, ask your hosting provider to update / install it.
