If in file Zend/CodeGenerator/Php/Docblock/Tag.php to remove lines require_once ' Zend/CodeGenerator/Php/Docblock/Tag/Param.php '; and require_once ' Zend/CodeGenerator/Php/Docblock/Tag/Return.php ';

Then works

I've tried the following on trunk and cannot reproduce:

set_include_path('/Users/ralphschindler/Projects/ZFStandardTrunk/library'); // current trunk
require_once "Zend/CodeGenerator/Php/Class.php";
$foo = new Zend_CodeGenerator_Php_Class();
var_dump($foo); // works

If you can supply more information, like a backtrace or something, please do and reopen.

Here is a debug backtrace on 1.10.5:

Issue appears to be that the Param.php requires Tag.php, and Tag.php requires Param.php. It includes Param.php before the class has been initialized.

Please reopen the issue

Can reproduce on trunk with the following code:

set_include_path('/path/to/library'); // current trunk
require_once "Zend/CodeGenerator/Php/Docblock/Tag.php";
$foo = new Zend_CodeGenerator_Php_Docblock_Tag();

As mentioned by ~dontcare], it is due to spurious require_once statements in Zend_CodeGenerator_Php_Docblock_Tag causing a require_once loop. The statements were added in [14194, back before the plugin loader was being used, and should have been removed in 14942.

The above code gives the following order for required files:

The class instantiation isn't even necessary to reproduce:

set_include_path('/path/to/library'); // current trunk
require_once "Zend/CodeGenerator/Php/Docblock/Tag.php"; // Fatal

The above code gives the following order for required files:

Zend/CodeGenerator/Php/Docblock/Tag.php Zend/CodeGenerator/Php/Abstract.php Zend/CodeGenerator/Php/Docblock/Tag/Param.php

If the Abstract class is manually required prior to the Tag class, the error is not seen:

set_include_path('/path/to/library'); // current trunk
require_once 'Zend/CodeGenerator/Php/Abstract.php';
require_once "Zend/CodeGenerator/Php/Docblock/Tag.php"; // works
