3.15.1 Global Functions
ada perubahan tertangguh untuk seksyen ini. More information about translations
Here are CakePHP's globally available functions. Many of them are convenience wrappers for long-named PHP functions, but some of them (like uses()) can be used to include code or perform other useful functions. Chances are if you're constantly wanting a function to accomplish an oft-used task, it's here.
3.15.1.1 __
ada perubahan tertangguh untuk seksyen ini. More information about translations
__(string $string_id, boolean $return = false)
This function handles localization in CakePHP applications. The $string_id identifies the ID for a translation, and the second parameter allows you to have the function automatically echo the string (the default behavior), or return it for further processing (pass a boolean true to enable this behavior).
Check out the Localization & Internationalization section for more information.
3.15.1.2 a

a(mixed $one, $two, $three...)
Returns an array of the parameters used to call the wrapping function.
print_r(a('foo', 'bar'));
// output:
array(
[0] => 'foo',
[1] => 'bar'
) print_r(a('foo', 'bar'));// output:array([0] => 'foo',[1] => 'bar')
3.15.1.3 aa
ada perubahan tertangguh untuk seksyen ini. More information about translations
aa(string $one, $two, $three...)
Used to create associative arrays formed from the parameters used to call the wrapping function.
print_r(aa('a','b'));
// output:
array(
'a' => 'b'
) print_r(aa('a','b'));// output:array('a' => 'b')

Convenience wrapper for echo().
3.15.1.10 env
ada perubahan tertangguh untuk seksyen ini. More information about translations
env(string $key)
Gets an environment variable from available sources. Used as a backup if $_SERVER or $_ENV are disabled.
This function also emulates PHP_SELF and DOCUMENT_ROOT on unsupporting servers. In fact, it's a good idea to always use env() instead of $_SERVER or getenv() (especially if you plan to distribute the code), since it's a full emulation wrapper.
