I have been trying to figure out how to go about doing this but I am not quite sure how.
Here is an example of what I am trying to do:
class test { public newTest(){ function bigTest(){ //Big Test Here } function smallTest(){ //Small Test Here } } public scoreTest(){ //Scoring code here; } }Here is the part I am having problems with, how do I call bigTest()?

Try this one:
class test { public function newTest(){ $this->bigTest(); $this->smallTest(); } private function bigTest(){ //Big Test Here } private function smallTest(){ //Small Test Here } public function scoreTest(){ //Scoring code here; } } $testObject = new test(); $testObject->newTest(); $testObject->scoreTest();answered Nov 12, 2009 at 20:38

The sample you provided is not valid PHP and has a few issues:
public scoreTest() { ... }is not a proper function declaration -- you need to declare functions with the 'function' keyword.
The syntax should rather be:
public function scoreTest() { ... }Second, wrapping the bigTest() and smallTest() functions in public function() {} does not make them private — you should use the private keyword on both of these individually:
class test () { public function newTest(){ $this->bigTest(); $this->smallTest(); } private function bigTest(){ //Big Test Here } private function smallTest(){ //Small Test Here } public function scoreTest(){ //Scoring code here; } }Also, it is convention to capitalize class names in class declarations ('Test').
Hope that helps.

I think you are searching for something like this one.
class test { private $str = NULL; public function newTest(){ $this->str .= 'function "newTest" called, '; return $this; } public function bigTest(){ return $this->str . ' function "bigTest" called,'; } public function smallTest(){ return $this->str . ' function "smallTest" called,'; } public function scoreTest(){ return $this->str . ' function "scoreTest" called,'; } } $test = new test; echo $test->newTest()->bigTest();

To call any method of an object instantiated from a class (with statement new), you need to "point" to it. From the outside you just use the resource created by the new statement. Inside any object PHP created by new, saves the same resource into the $this variable. So, inside a class you MUST point to the method by $this. In your class, to call smallTest from inside the class, you must tell PHP which of all the objects created by the new statement you want to execute, just write:
$this->smallTest();

In order to have a "function within a function", if I understand what you're asking, you need PHP 5.3, where you can take advantage of the new Closure feature.
So you could have:
public function newTest() { $bigTest = function() { //Big Test Here } }answered Nov 12, 2009 at 20:39

class sampleClass { public function f1() { return "f1 run"; } public function f2() { echo ("f2 run" ); $result = $this->f1(); echo ($result); } f2(); }
output :
f2 run f1 run

You need to call newTest to make the functions declared inside that method “visible” (see Functions within functions). But that are then just normal functions and no methods.

You can also use self::CONST instead of $this->CONST if you want to call a static variable or function of the current class.
