CLI php won't read php.ini display_errors value

[pnj]

I've just installed php 5.3.3 command line on windows 7 via the thread unsafe .msi installer. 

 

I can't get php to read the display_errors value in php.ini.

 

When I run phpinfo(), the following lines reference php.ini:

 

Configuration File (php.ini) Path => C:\Windows
Loaded Configuration File => C:\Program Files\PHP\php.ini

 

I've placed php.ini files in both those locations with the following lines (among others):

 
display_errors = On
display_startup_errors = On

 

But phpinfo() tells me:

display_errors => STDOUT => Off

 

I can turn it on using

ini_set('display_errors','On');

 

but scripts with syntax errors still die silently.

 

Any suggestions?

 

Thanks!
