Description:
------------
I'm using PEAR 1.9.0, but newer version are also affected.

PEAR fails to open and parse an empty php.ini file because the return value of file() is not checked correctly (see attached patch).

It's easy to end up with an empty php.ini file when you set the php_ini configuration variable to a custom location.

The attached patch applies to SVN r313186

Best regards

PS: It's not clear where this bug should be reported, the PEAR website doesn't seem to have the concept of bugs in PEAR itself but only in packages…

Test script:
---------------
#!/bin/sh

php_ini=`mktemp`

pear config-set php_ini $php_ini user
pecl install mongo

rm -f $php_ini


Expected result:
----------------
[..]
install ok: channel://pecl.php.net/mongo-1.2.1
Extension mongo enabled in php.ini
% 

Actual result:
--------------
[...]
install ok: channel://pecl.php.net/mongo-1.2.1
php.ini "/tmp/tmp.V6wU8jpMA4" could not be read
You should add "extension=mongo.so" to php.ini

It's bogus anyway.

It's not supposed to suggest that.

You'll have to set extension_dir in your php.ini so an extension is found and can 
be loaded. The complete path is never added to extension=foo.so.

Sorry, somehow I f'd up the comment, what I meant to say was:

Please report bugs for pear on http://pear.php.net/pear

Also, your patch does literally nothing. !$foo and $foo === false are the same 
thing.

file() returns false when the path is incorrect.

Anyhow, please report over at PEAR.

!$foo and $foo === false are not the same thing when $foo is an empty string.

I'm waiting for a confirmation e-mail to submit the bug to PEAR. It's not really clear if any kind of registration is required or if it works like here.
