Bug description:ini_get() better consistent behavior with booleans
Description:
------------
The ini_get("boolean_setting") function may return several kind of value
when dealing with boolean settings, as explained in the documentation :
> Note: When querying boolean values
> A boolean ini value of off will be returned as an empty string or "0"
while a > boolean ini value of on will be returned as "1". The function can
also return > the literal string of INI value.
The last part is a really annoying behavior, as to get the boolean value of
a boolean setting, the following must be done :
$my_boolean = ini_get("boolean_setting");
if ($my_boolean === "0") {
$my_boolean = false;
} else {
$my_lowered_boolean = strtolower($my_boolean);
if ($my_lowered_boolean === "false" ||
$my_lowered_boolean === "off" ||
$my_lowered_boolean === "no") {
$my_boolean = false;
} else {
$my_boolean = true;
}
}
I've noticed that the behavior is different when the setting has been set
in php.ini, or in apache's configuration. Settings from php.ini are always
set to "" or "1", whereas apache's settings (via php_value) are set to
their litteral value (ie: "FalsE", "oFF", "off", ...). Lot of chances that
the devs miss it!
When the setting doesn't exist, "" or null is returned. So that's quite a
mess to deal with such values, and there is no way to test the existence of
a setting.
Test script:
---------------
# Exemple 1
# httpd.conf
php_admin_value safe_mode FaLsE
# php script
ini_get("safe_mode") === "FaLsE"
---
# Exemple 2
# php.ini
safe_mode = FaLsE
# php script
ini_get("safe_mode") === ""
Expected result:
----------------
It would be a great enhancement no to depend on what is written in
configuration files, but to depend on the way it's being interpreted by the
engine.
# Example 1
# httpd.conf
php_admin_value safe_mode FaLsE
# php script
ini_get("safe_mode") === false
---
# Example 2
# php.ini
safe_mode = FaLsE
# php script
ini_get("safe_mode") === false
---
# Example 3
# Non existing setting
ini_get("unset_setting") === null
Actual result:
--------------
A disabled boolean setting may return one of the following:
ini_get("safe_mode") === "FaLsE"
ini_get("safe_mode") === "Off"
ini_get("safe_mode") === "oFF"
ini_get("safe_mode") === "0"
...
An enabled boolean setting may return one of the following:
ini_get("safe_mode") === "truE"
ini_get("safe_mode") === "On"
ini_get("safe_mode") === "oN"
ini_get("safe_mode") === "1"
...
An unset setting may return one of the following:
ini_get("safe_mode") === ""
ini_get("safe_mode") === null
