I was having some trouble using include_path in my .htaccess file because I was running PHP and Apache on a windows platform.  The difference is you have to separate paths using the semicolon(;) not the colon (:)

Example:

php_value include_path ".;C:\www\scripts;C:\php\;C:\php\PEAR"

Be careful with setting an output_handler, as you can't use ini_set() to change it. *sigh*



In my php.ini I have this for my web pages (and I want it): 



  output_handler = ob_gzhandler



But this causes my command line scripts to not show output until the very end.



#!/usr/bin/php -q

<?php

ini_set('output_handler', 'mb_output_handler');

echo "\noutput_handler => " . ini_get('output_handler') . "\n";

?>



root@# ./myscript.php

output_handler => ob_gzhandler



Apparently (acording to Richard Lynch):



> TOO LATE!

> The ob_start() has already kicked in by this point.

> ob_flush() until there are no more buffers.

set PHP_INI_PERDIR settings in a .htaccess file with 'php_flag' like this:



php_flag register_globals off

php_flag magic_quotes_gpc on

When your ISP does not allow you to add the default include directories - it might be useful to extend the 'include_path' variable:



<?  ini_set('include_path',ini_get('include_path').':../includes:');  ?>

You can also find the Apache config files by useing command httpd -V

To find the apache php settings try something like this.

> cd /etc/apache2

> grep -r -n -i  safe_mode_exec_dir *.conf

or

> grep -r -n -i safe_mode.*On *.conf



If you find a gererated file, obviously you need to find the source template for it, to change what's needed there.



I just wasted a sunny Sunday on searching for where the heck safe_mode_exec_dir was changed.



And yes, Local Value in phpinfo does mean 'changed between the php.ini file and here', as you would think.



If you have an automated virtual host configuration, such as confixx, php ini values can be spread across very many files.



They can be changed in apache config files, that can have any name, but usually will end on .conf, besides in .htaccess files.

To change settings from .htaccess files, it is also required that the directory permissions configured in Apache allow this.



The <Directory /foo/bar> entry in httpd.conf MUST contain "AllowOverride All" or at least "AllowOverride Options" to read PHP settings from the .htaccess file.



E.g. in Fedora Core 2, the default settings for /var/www/html/ are "AllowOverride None", so changing PHP settings via .htaccess for applications installed below /var/www/html/ will not work.

While this doesn't belong in the manual, it should be useful for people looking on this page for zend_optimizer.* ini options, which are commonly installed:



Information on the "zend_optimizer.optimization_level" and "zend_optimizer.enable_loader" options is available at:

Where you want set ini in .htaccess or vhosts directives, if the value of directive is boolean , use php_flag, else if the value is a string use php_value.



Ex : php_value include_path /home/user/include

php_flag zlib.output_compression On

If you set something using php_admin_value in httpd.conf it is then not possible to be set the value at runtime, even if it's NOT PHP_INI_SYSTEM. 



Just an interesting note for Server admins this might come in handy to disable setting of certain things... like allow_url_fopen.
