The @param tag is used to document a single argument of a function or method.
With the @param tag it is possible to document the type and function of a single argument of a function or method. When provided it MUST contain a Type to indicate what is expected; the description on the other hand is OPTIONAL yet RECOMMENDED in case of complicated structures, such as associative arrays.
The @param tag MAY have a multi-line description and does not need explicit delimiting.
It is RECOMMENDED when documenting to use this tag with every function and method. Exceptions to this recommendation are:
This tag MUST NOT occur more than once per argument in a PHPDoc and is limited to Structural Elements of type method or function.
Structural Elements of type method or function, that are tagged with the @param tag, will have additional information in the section regarding Arguments.
If the return Type is a class that is documented by phpDocumentor, then a link to that class’ documentation is provided.
Note
phpDocumentor supports @param tags which omit the name, this is NOT RECOMMENDED but provided for compatibility with existing projects.
Note
phpDocumentor will try to analyze correct usage and presence of the @param tag; as such it will provide error information in the following scenarios:
1 2 3 4 5 6 7 8 9 10 11 | /**
* Counts the number of items in the provided array.
*
* @param mixed[] $items Array structure to count the elements of.
*
* @return int Returns the number of elements.
*/
function count(array $items)
