Chapter 6 Namespaces

[Christopher Bergin]

I've been trying to complete the exercise in Chapter 6 pertaining to namespaces.(scripts 6.9, 6.10)

When attempting to run the script, I initially received an error like this:

 

Warning: Unexpected character in input: '\' (ASCII=92) state=1;

 

I even tried running the author's scripts and received the same error. After looking on the PHP site for more information, I tried deleting the initial '\' to the first object instantiation at the line number where the error specified:

 

$hr = new MyNamespace\Company\Department('Accounting');

 

This resulted in a blank page. Further tinkering around resulted in an Internal Server Error. Since I'm using a hosting service, I've sent them an inquiry for directions to access the server log. In the meantime, I was wondering if anyone could shed light on this issue. The directory was configured as the book suggested. The version of PHP that I'm using is 5.3.

Are you sure you are on PHP 5.3? A small search teaches me that this error is common when Namespaces are not supported.

 

Try printing out the version information to confirm what your host tells you:

 

<?php
echo 'Current PHP version: ' . phpversion();
?>

[Christopher Bergin]

yes, version 5.3.13. It's not important. I just thought I'd put it out there. I was able to recover the cgiErrorlog so I'll examine that.

[Antonio Conte]

It matters a bit. Namespace support was added in 5.3, so at least that's not the problem.

 

Since you got a blank page, try adding these lines to the top of your file:

 

 

<?php
// Display errors
ini_set('display_errors', 1);

// Full error reporting
 error_reporting(-1);

?>
 

Do you get any more information now?

thank-you Antonio, your error script pointed me to an incorrect directory setting in my include file. Everything works now. I'm going to hold on to that little nugget of code.

Glad you solved it.
