string Inflector::singularize(string $word)

Returns the singular of the $word.

• param string $word the english word to singularize

string Inflector::titleize(string $word [, bool $ucAll = false])

Converts an underscored or CamelCase word into a English sentence.

• param string $words
• param $ucAll whether to set all words to uppercase

string Inflector::camelize(string $word)

• param string $word the word to CamelCase

string Inflector::camel2words(string $word [, bool $ucwords = false])

Converts a CamelCase name into space-separated words.

For example, 'PostTag' will be converted to 'Post Tag'.

• param string $name the string to be converted

string Inflector::camel2id(string $name [, string $separator = '-' [, bool $strict = false]])
