Nice, but...
Isn't there like a way where you can use these both separate?  , I tried these:
...*removed*
Okay I made a little solution for the selecting weather to chain your class or not, it's fussy though, but it helps I guess  :
PHP Code:
<?php
// December 19 2009 [10:02 a.m. MS]
class person {
private $name;
private $age;
private $chain; // want to chain? false (/no) by default
function __construct($chain=false) {
$this->chain = $chain;
if($this->chain == false) { // Set to false by default
return false;
} else {
return true;
}
}
public function set_name($name) {
if($this->chain == false) {
return $this->name = $name;
} else {
$this->name = $name;
return $this;
}
}
public function set_age($age) {
if($this->chain == false) {
return $this->age = $age;
} else {
$this->age = $age;
return $this;
}
}
public function introduce() {
if(empty($this->name)) {
print("I need a name!");
} else if(empty($this->age)) {
print("I dont have an age!");
} else {
printf("Hello there, my name is <b>%s</b> and I am <b>%s</b> years old.", $this->name, $this->age);
}
}
}
$person = new person();
$name = "Jarod";
$age = 17;
echo "Normal Method";
echo "<br />";
echo $person->set_name($name) . "<br />";
echo $person->set_age($age) . "<br />";
$person->introduce();
echo "<br />";
echo "<br />";
echo "<br />";
echo "Chaining Method";
echo "<br />";
$person = new person(true); // chaining method
$person->set_name($name)->set_age($age)->introduce();
/** OUTPUT::>>
* Normal Method
* Jarod
* 17
* Hello there, my name is Jarod and I am 17 years old.
*
*
* Chaining Method
* Hello there, my name is Jarod and I am 17 years old.
*/
?>
