__construct not working

onlyican · November 14, 2006

Hey guys

This is a bit strange

I been working on a large script, on my local machine

I uploaded it to my server, and was getting erorrs left right and centre

I found out that the __construct function is not running when I call the function

I thought I will double check this, so I built a dummy class.

The code is something like this

FILE: myclass.php
[code]

<?php

class test{

function __construct(){

echo "This is the first function, which should run automaticly \n";

}

function AddedFunction(){

echo "This function should only be called when I call it \n";

}

}

?>
[/code]
then

FILE: run.php

[code]

<html>

<head>

<title>Test Class</title>

</head>

<body>

<?php

require("myclass.php");

echo "Here, I will call start the new object for the class \n\n";

$dummy = new test;

echo "Now I will call the Extra Function \n\n";

$dummy->AddedFunction();

echo "End \n";

?>

</body>

</html>
[/code]

Nothing too clever there

On my local machine, which is running PHP V 5.1.1

I get the following

[quote]

Here, I will call start the new object for the class

This is the first function, which should run automaticly

Now I will call the Extra Function

This function should only be called when I call it

End
[/quote]
Which is correct

BUT

On my server, which is running PHP V 4.4.3 I get

[quote]

Here, I will call start the new object for the class

Now I will call the Extra Function

This function should only be called when I call it

End
[/quote]
Which is missing the line from the construct function

Any ideas

Sorted now

In php V4 the function __construct does not work

What you can do, which works in V5 as well
Name the function you want to construct the same as the class name

for example

[code]
<?php

class MyClass{

function MyClass(){

}
}[/code]

__construct is only a magic function as of php5, the php4 syntax is to use the name of the class as the constructor:
[code]<?php

class FooBar
{
/* constructor */
function FooBar()
{}
}

?>[/code]

Yes, there are actually a bunch of "Magic Methods" added to classes in PHP5. See [url=http://us2.php.net/manual/en/language.oop5.magic.php]this manual page[/url] for a full listing and what they do.
