- short_open_tag
boolean
Tells whether the short form (<? ?>)
of PHP's open tag should be allowed. If you want to use PHP in
combination with XML, you can disable this option in order to
use <?xml ?> inline. Otherwise, you
can print it with PHP, for example: <?php echo '<?xml
version="1.0"'; ?>. Also if disabled, you must use the
long form of the PHP open tag (<?php ?>).
Note:
This directive also affects the shorthand <?=,
which is identical to <? echo. Use of this
shortcut requires short_open_tag
to be on.
- asp_tags
boolean
Enables the use of ASP-like <% %> tags in addition to
the usual <?php ?> tags. This includes the
variable-value printing shorthand of <%= $value %>. For
more information, see Escaping from HTML.
Note:
Support for ASP-style tags was added in 3.0.4.
- precision
integer
The number of significant digits displayed in floating point numbers.
- y2k_compliance
boolean
Enforce year 2000 compliance (will cause problems with non-compliant browsers)
- allow_call_time_pass_reference
boolean
Whether to enable the ability to force arguments to be passed by reference
at function call time. This method is deprecated and is likely to be
unsupported in future versions of PHP/Zend. The encouraged method of
specifying which arguments should be passed by reference is in the function
declaration. You're encouraged to try and turn this option Off and make
sure your scripts work properly with it in order to ensure they will work
with future versions of the language (you will receive a warning each time
you use this feature, and the argument will be passed by value instead of by
reference).
Passing arguments by reference at function call time was deprecated for
code cleanliness reason. Function can modify its argument in
undocumented way if it didn't declared that the argument is passed by
reference. To prevent side-effects it's better to specify which
arguments are passed by reference in function declaration only.

- expose_php
boolean
Decides whether PHP may expose the fact that it is installed on the server
(e.g. by adding its signature to the Web server header). It is no security
threat in any way, but it makes it possible to determine whether you use PHP
on your server or not.
- zend.ze1_compatibility_mode
boolean
Enable compatibility mode with Zend Engine 1 (PHP 4). It affects
the cloning, casting, and comparing of objects.
