DescriptionFactory
in package
Creates a new Description object given a body of text.
Descriptions in phpDocumentor are somewhat complex entities as they can contain one or more tags inside their
body that can be replaced with a readable output. The replacing is done by passing a Formatter object to the
Description object's render method.
In addition to the above does a Description support two types of escape sequences:
-
@to escape the@character to prevent it from being interpreted as part of a tag, i.e.{@link} -
}to escape the}character, this can be used if you want to use the}character in the description of an inline tag.
If a body consists of multiple lines then this factory will also remove any superfluous whitespace at the beginning of each line while maintaining any indentation that is used. This will prevent formatting parsers from tripping over unexpected spaces as can be observed with tag descriptions.

lex(string $contents) : array<string|int, string>
Parameters
- $contents : string

removeSuperfluousStartingWhitespace()
Removes the superfluous from a multi-line description.
private
removeSuperfluousStartingWhitespace(string $contents) : string
When a description has more than one line then it can happen that the second and subsequent lines have an additional indentation. This is commonly in use with tags like this:
@since 1.1.0 This is an example
description where we have an
indentation in the second and
subsequent lines.
If we do not normalize the indentation then we have superfluous whitespace on the second and subsequent lines and this may cause rendering issues when, for example, using a Markdown converter.
Parameters
- $contents : string
