Parameters
-
string$version The version that added this deprecation warning.
-
string$message The message to output as a deprecation warning.
-
int$stackFrame optional The stack frame to include in the error. Defaults to 1 as that should point to application/plugin code.
Returns
voidenv() ¶
env(string $key, string|bool|null $default = null): string|float|int|bool|nullGets an environment variable from available sources, and provides emulation for unsupported or inconsistent environment variables (i.e. DOCUMENT_ROOT on IIS, or SCRIPT_NAME in CGI mode). Also exposes some additional custom environment information.
Parameters
-
string$key Environment variable name.
-
string|bool|null$default optional Specify a default value in case the environment variable is not defined.
Returns
string|float|int|bool|nullLinks
h() ¶
h(mixed $text, bool $double = true, string|null $charset = null): mixedConvenience method for htmlspecialchars.
Parameters
-
mixed$text Text to wrap through htmlspecialchars. Also works with arrays, and objects. Arrays will be mapped and have all their elements escaped. Objects will be string cast if they implement a
__toStringmethod. Otherwise, the class name will be used. Other scalar types will be returned unchanged.-
bool$double optional Encode existing html entities.
-
string|null$charset optional Character set to use when escaping. Defaults to config value in
mb_internal_encoding()or 'UTF-8'.
Returns
mixedLinks
namespaceSplit() ¶
namespaceSplit(string $class): array{0: string, 1: string}Split the namespace from the classname.
Commonly used like list($namespace, $className) = namespaceSplit($class);.
Parameters
-
string$class The full class name, ie
Cake\Core\App.
Returns
array{0: string, 1: string}pathCombine() ¶
pathCombine(list<string> $parts, bool|null $trailing = null): stringCombines parts with a forward-slash /.
Skips adding a forward-slash if either / or \ already exists.
Parameters
-
list<string>$parts -
bool|null$trailing optional Determines how trailing slashes are handled
- If true, ensures a trailing forward-slash is added if one doesn't exist
- If false, ensures any trailing slash is removed
- if null, ignores trailing slashes
Returns
stringpj() ¶
pj(mixed $var): mixedJSON pretty print convenience function.
In terminals this will act similar to using json_encode() with JSON_PRETTY_PRINT directly, when not run on CLI
will also wrap <pre> tags around the output of given variable. Similar to pr().
This function returns the same variable that was passed.
Parameters
-
mixed$var Variable to print out.
Returns

pluginSplit() ¶
pluginSplit(string $name, bool $dotAppend = false, string|null $plugin = null): arraySplits a dot syntax plugin name into its plugin and class name. If $name does not have a dot, then index 0 will be null.
Commonly used like
list($plugin, $name) = pluginSplit($name);Parameters
-
string$name The name you want to plugin split.
-
bool$dotAppend optional Set to true if you want the plugin to have a '.' appended to it.
-
string|null$plugin optional Optional default plugin to use if no plugin is found. Defaults to null.
Returns
arrayLinks
pr() ¶
pr(mixed $var): mixedprint_r() convenience function.
In terminals this will act similar to using print_r() directly, when not run on CLI
print_r() will also wrap <pre> tags around the output of given variable. Similar to debug().
This function returns the same variable that was passed.
Parameters
-
mixed$var Variable to print out.
Returns

toBool() ¶
toBool(mixed $value): bool|nullConverts a value to boolean.
1 | '1' | 1.0 | true - values returns as true 0 | '0' | 0.0 | false - values returns as false Other values returns as null.
Parameters
-
mixed$value The value to convert to boolean.
Returns
bool|nulltoFloat() ¶
toFloat(mixed $value): float|nullConverts a value to a float.
This method attempts to convert the given value to a float. If the conversion is successful, it returns the value as an float. If the conversion fails, it returns NULL.
String values are trimmed using trim().
Parameters
-
mixed$value The value to be converted to a float.
Returns
float|nulltoInt() ¶
toInt(mixed $value): int|nullConverts a value to an integer.
This method attempts to convert the given value to an integer. If the conversion is successful, it returns the value as an integer. If the conversion fails, it returns NULL.
String values are trimmed using trim().
Parameters
-
mixed$value The value to be converted to an integer.
Returns
int|nulltoString() ¶
toString(mixed $value): ?stringConverts the given value to a string.
This method attempts to convert the given value to a string.
If the value is already a string, it returns the value as it is.
null is returned if the conversion is not possible.
Parameters
-
mixed$value The value to be converted.
Returns
?stringtriggerWarning() ¶
triggerWarning(string $message): voidTriggers an E_USER_WARNING.
Parameters
-
