3.15.1 Global Functions
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 __
__(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
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')
3.15.1.4 am
am(array $one, $two, $three...)
Merges all the arrays passed as parameters and returns the merged array.
3.15.1.5 config
Can be used to load files from your application config-folder via include_once. Function checks for existance before include and returns boolean. Takes an optional number of arguments.
Example: config('some_file', 'myconfig');
3.15.1.6 convertSlash
convertSlash(string $string)
Converts forward slashes to underscores and removes the first and last underscores in a string. Returns the converted string.
3.15.1.7 countdim
countdim(array $array)
Returns the number of dimensions in the supplied array.
3.15.1.8 debug
debug(mixed $var, boolean $showHtml = false)
If the application's DEBUG level is non-zero, $var is printed out. If $showHTML is true, the data is rendered to be browser-friendly.
3.15.1.9 e
e(mixed $data)
Convenience wrapper for echo().
3.15.1.10 env
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.
3.15.1.11 fileExistsInPath
fileExistsInPath(string $file)
Checks to make sure that the supplied file is within the current PHP include_path. Returns a boolean result.
3.15.1.12 h
h(string $text, string $charset = null)
Convenience wrapper for htmlspecialchars().
3.15.1.13 ife
ife($condition, $ifNotEmpty, $ifEmpty)
Used for ternary-like operations. If the $condition is non-empty, $ifNotEmpty is returned, else $ifEmpty is returned.
3.15.1.14 low
low(string $string)
Convenience wrapper for strtolower().
3.15.1.15 paths
paths()
Get CakePHP basic paths as an indexed array. Resulting array will contain array of paths indexed by: Models, Behaviors, Controllers, Components, and Helpers.
3.15.1.16 pr
pr(mixed $var)
Convenience wrapper for print_r(), with the addition of wrapping <pre> tags around the output.
3.15.1.17 r
r(string $search, string $replace, string $subject)
Convenience wrapper for str_replace().
3.15.1.18 stripslashes_deep
stripslashes_deep(array $value)
Recursively strips slashes from the supplied $value. Returns the modified array.
3.15.1.19 up
up(string $string)
Convenience wrapper for strtoupper().
3.15.1.20 uses
uses(string $lib1, $lib2, $lib3...)
Used to load CakePHP's core libraries (found in cake/libs/). Supply the name of the library's file name without the '.php' extension.
