[PHP] Zend Server, PEAR, and PHAR error

Some time ago I was trying to install PEAR with default installation of Zend Server. To do that, you have to run a following command:

C:\Program Files (x86)\Zend\ZendServer\bin\go-pear.bat

That resulted in a problem with PHAR archive:

phar "C:\Program Files (x86)\Zend\ZendServer\bin\PEAR\go-pear.phar" does not have a signature
PHP Warning:  require_once(phar://go-pear.phar/index.php): failed to open stream: phar error: invalid url or non-existent phar "phar://go-pear.phar/index.php" in C:\Program Files (x86)\Zend\ZendServer\bin\PEAR\go-pear.phar on line 1236

To solve that problem, you have to either modify php.ini file, adding following directive:

phar.require_hash=0

Or, you can use it one-time only, setting that configuration option in command line:

C:\Program Files (x86)\Zend\ZendServer\bin\PEAR> php -d phar.require_hash=0 go-pear.phar

The latter form is preferred, as disabling checking signatures is considered a security flaw.
