PHP: Making a class structure help

[tmull11336]

I have now tried to make to different classes using PHP. One for MySQL and one for FTP. I tried to use an example I got from a book for the MySQL. I get this error when I try to invoke both of the classes:
Parse error: parse error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /udrive/student/tmullin/public_html/WorkStudy/mysql.class.php on line 4
Does anyone know how I can resolve this problem?
Here is the source for my class:
<?php
//MySQL class to call from
class mysql{
private $linkID; //MySQL link ID
private $host; //MySQL server host
private $username; //MySQL user ID
private $password; //MySQL password
private $DB; //MySQL database
private $result; //MySQL query result
private $querycount; //Total amount of queries

  //Class constructor. Initializes data for host, user, password, and database fields
  function_construct( $host, $username, $password, $DB ){
     $this->host = $host;
	 $this->username = $username;
	 $this->password = $password;
	 $this->DB = $DB;
  } 

  //Function to connect to the MySQL database server
  function connect() 
  {
     try{
	    $this->linkID = @mhysql_connect( "$this->host, $this->username, $this->password" );
		if( ! $this->linkID )
		   throw new Exception( "Could not connect to the MySQL server." );
	 }
	 //Catch exception if the connection to the MySQL database wasn't made and output it
	 catch(Exception $e)
	 {  die( $e->getMessage() );
	 }
  }

your missing a closing } for your class, stick it at the end.

Also, try indenting your code, it'll make it easier to spot these mistakes

I have an closing } at the end of the document and I do indent to make it easier to decipher but I am still geting this error. Here is my entire code segment:
<?php
//MySQL class to call from
class mysql{
private $linkID; //MySQL link ID
private $host; //MySQL server host
private $username; //MySQL user ID
private $password; //MySQL password
private $DB; //MySQL database
private $result; //MySQL query result
private $querycount; //Total amount of queries

  //Class constructor. Initializes data for host, user, password, and database fields
  function_construct( $host, $username, $password, $DB ){
     $this->host = $host;
	 $this->username = $username;
	 $this->password = $password;
	 $this->DB = $DB;
  } 

  //Function to connect to the MySQL database server
  function connect() 
  {
     try{
	    $this->linkID = @mhysql_connect( "$this->host, $this->username, $this->password" );
		if( ! $this->linkID )
		   throw new Exception( "Could not connect to the MySQL server." );
	 }
	 //Catch exception if the connection to the MySQL database wasn't made and output it
	 catch(Exception $e)
	 {  die( $e->getMessage() );
	 }
  }

  //Select the MySQL database
  function select()
  {
     try{
	    if( ! @mysql_select_db( $this->DB, $this->linkID ) )
		   throw new Exception( "Could not connect to the MySQL database." );
	 }
	 //Catch exception if the selected database is not connected and output it
	 catch(Exception $e){
	    die( $e->getMessage() );
	 }
  }
 /* 
  //Execute a database query
  function query( $query )
  {  try
     {
     $this->result = @mysql_query( $query, $this->linkID );
	 if( !$this->result )
	    throw new Exception( "The database query failed." );
	 }
	 catch( Exception $e ) 
	 {
	    echo( $e->getMessage() );
	 }
	 $this->querycount++;
	 return $this->result;
  }

  //Determine total number of rows affected by query
  function affectedRows ()
  {  $count = @msql_affected_rows( $this->linkID );
     return $count;
  }

  //Determine total number of rows returned by query
  function numRows ()
  {  $count = @mysql_num_rows( $this->result );
     return $count;
  }

  //Return query result row as an object
  function fetchObject ()
  {  $row = @mysql_fetch_object( $this->result );
     return $row;
  }

  //Return query result row as an indexed array
  function fetchRow ()
  {  $row = @mysql_fetch_row( $this->result );
     return $row;
  }

  //Return query result row as an associative array
  function fecthArray ()
  {  $row = @mysql_fetch_array( $this->result );
     return $row;
  }*/

}

OHHH, I have also commented out some of the stuff to just try to make sure it connects and works before trying the other functions.

I have figured out a way to get my code to work. I'm not sure if it is a version of PHP or something but don't use "private" to define your variables for the class. For PHP, it worked when I just used "var" to define the variables. Just a heads up for anyone trying to create a class!
