PHP Class example - php

Question

Can anyone help me with php classes example. I have to make class "information" that has information about users: id, email, password, first name, last name, phone.
Also, class must have a method to print all the user data on the output.

Answer 1

It's really simple skeleton, because you didn't try anything, so just for you to have idea how it works...
class User
{
private $id;
private $email;
// ...
public function __construct($id, $email...)
{
$this->id = $id;
$this->email = $email;
// ...
}
public function printAll()
{
return $this->id . ' ' . $this->email;
}
}

Here is an example of a PHP class:
class DBIGenerator{
private $table;
private $name;
private $path;
public function __construct($table,$name='default_file.php',
$path='DEFAULTPATH/'){
$this->table=$table;
$this->name=$name;
$this->path=$path;
}
public function generate(){
// build class header
$str='<?php class '.$this->name.'{';
if(!$result=mysql_query('SHOW COLUMNS FROM '.$this->table)){
throw new Exception('Failed to run query');
}
// build data member declaration
if(mysql_num_rows($result)<1){
throw new Exception('Not available columns in table');
}
$methods='';
while($row=mysql_fetch_array($result,MYSQL_ASSOC)){
$str.='private $'.$row['Field'].'=\'\';';
$methods.='public function set'.$row['Field'].'($'.$row
['Field'].'){$this->'.$row['Field'].'=$'.$row
['Field'].';}';
$methods.='public function get'.$row['Field'].'(){return
$this->'.$row['Field'].';}';
// store field names in array
$fields[]=$row['Field'];
}
// build empty constructor
$str.='public function __construct(){}';
// build modifiers and accessors
$str.=$methods;
// build load() method
$str.='public function load(){$r=mysql_query("SELECT * FROM
'.$this->table.' WHERE id=\'$this->id\'");';
$str.='return mysql_fetch_array($r,MYSQL_ASSOC);}';
// build submit() method
$str.='public function submit(){mysql_query("INSERT INTO '.$this-
>table.' SET ';
foreach($fields as $field){
$str.=($field!='id')?$field.'=\'$this->'.$field.'\',':'';
}
$str.='");$this->id=mysql_insert_id();';
$str=preg_replace("/,\"/","\"",$str).'}';
// build update() method
$str.='public function update(){mysql_query("UPDATE '.$this-
>table.' SET ';
foreach($fields as $field){
$str.=($field!='id')?$field.'=\'$this->'.$field.'\',':'';
}
$str=preg_replace("/,$/","",$str);
$str.=' WHERE id=\'$this->id\'");}';
// build delete() method
$str.='public function delete(){mysql_query("DELETE FROM '.
$this->table.' WHERE id=\'$this->id\'");}';
$str.='}?>';
// open or create class file
if(!$fp=fopen($this->path.$this->name.'.php','w')){
throw new Exception('Failed to create class file');
}
// lock class file
if(!flock($fp,LOCK_EX)){
throw new Exception('Unable to lock class file');
}
// write class code to file
if(!fwrite($fp,$str)){
throw new Exception('Error writing to class file');
}
flock($fp,LOCK_UN);
fclose($fp);
// delete temporary variables
unset($fp,$str,$row,$fields,$field,$methods);
}
public function getObject(){
// check if class file exists
if(!file_exists($this->path.$this->name.'.php')){
throw new Exception('Failed to include class file');
}
require_once($this->path.$this->name.'.php');
// create data access object
return new $this->name;
}
}

Answer 4

Take a look at the snippet below as a basic way to implementing as expressed:
<?php
class information
{
public $id = 1;
public $email = "mail#mail.com";
public $pw = "A2D7DFEA88AC88"; //Don't forget, PW are usually hashed ;)
public function id() {
echo $this->id;
}
public function email() {
echo $this->email;
}
public function pw() {
echo $this->pw;
}
}
$test = new information();
$test->id;
?>
