PHP Classes won't run

[harbansb]

Hello,

I would like to start of by saying that I am fairly new to php, and would greatly appreciate any help. I am using PHP 5.4.2. When I write a class nothing is displayed, for example :

 

-------student.php ---------

<?php
class Student {
   private $name;

    public function __construct( $name ) {
        $this->name = $name;
    }
    public function getName() {
        return $this->name;
    }
}

$s = new Student('Mary');
echo( $s->getName() );
?>

 

Furthermore, if I try to echo a statement below the class definition it does not display anything, php before a class definition runs fine or on a separate file runs fine. For example:

-------student.php ---------

<?php
class Student {
   private $name;

    public function __construct( $name ) {
        $this->name = $name;
    }
    public function getName() {
        return $this->name;
    }
}
echo( "Hello World" );
?>

---------------------------

Nothing is displayed.

 

Maybe I have to change the php.ini file?

 

Any help would be greatly appreciated.

 

Thank You.

The examples posted work fine for me. o_O

Since php 5.4.x does not exist, that might be the problem.

LOL I didn't even see that.

Sorry 5.2.4

Sorry 5.2.4

 

I run PHP 5.2.4 as well, and the code executes just fine for me.

I'm going to guess a fatal runtime error and you are doing this on a system where error_reporting or display_errors is set to hide the errors that would help you when learning php, developing php code, or debugging php code. Add the following two lines after your <?php tag -

 

ini_set ("display_errors", "1");
error_reporting(E_ALL);

thanks, I just turned on error reporting, and updated the server to 5.2.6,  and still nothing comes up. I've changed the code to

 
<?php
ini_set ("display_errors", "1");
error_reporting(E_ALL);

class Student {}

echo( "Hello World" );
?>

 

Thanks for the help

I just ran the script and it said "Hello World".  Are you sure PHP is up and running on your server?

[harbansb]

yeah, here is a link to a page that just contains <? phpinfo() ?>

http://helm.harlemlive.org/phpinfo.php

 

thanks

If this helps here is the link to the above file

http://helm.harlemlive.org/Contacts/classes/index1.php

thanks.

That exact posted code (in post #7) should generate a fatal parse error due to a missing ;

 

The two lines I posted for adding to your script were based on information from you that an echo statement in the script before the class code produced output.

 

The two settings should be turned on in the php.ini since turning them on in your script won't have an effect if your script never runs.

I see no missing ;.

I'm probably (not)seeing things that should not be there (I jumped the gun and made that statement about the line with the empty class definition on it.)

 

Edit: His link to the page is now giving a parse error about an {. Based on the url and page name, I don't think the code in the first post was all the relevant code on that page.

sorry for the confusion I have changed the index1.php to

<?php
ini_set ("display_errors", "1");
error_reporting(E_ALL);

class B{ }

echo('hello');

?>

I have also added  the below code to the php.ini

ini_set ("display_errors", "1");
error_reporting(E_ALL);

 

It is giving the following error:

Parse error: syntax error, unexpected '{' in /home/site/helm/Contacts/classes/index1.php on line 5

Thanks

As long as the class name is not a reserved php keyword, what you have posted is correct and does work (the code you have posted in the first post and the latest post works for me as well.)

 

Either your php build is broken (OOP is part of the php core and to the best of my knowledge it cannot be turned off or disabled) or there is something about your file that is not right and is not being parsed properly.

[harbansb]

it seems to have corrected itself, thanks for the help.
