html_entity_decode()
is the opposite of
htmlentities()
in that it converts all HTML entities to their applicable
characters from
string
.
The optional second
quote_style
parameter lets you define what will be done with 'single' and
"double" quotes. It takes on one of three constants with the
default being
ENT_COMPAT
:
表 1Available
quote_style
constants
Constant Name | Description |
---|---|
ENT_COMPAT | Will convert double-quotes and leave single-quotes alone. |
ENT_QUOTES | Will convert both double and single quotes. |
ENT_NOQUOTES | Will leave both double and single quotes unconverted. |
The ISO-8859-1 character set is used as default
for the optional third
charset
. This defines the character set used in conversion.
注意 You might wonder why trim(html_entity_decode(' nbsp;')); doesn't reduce the string to an empty string, that's because the ' nbsp;' entity is not ASCII code 32 (which is stripped by trim() ) but ASCII code 160 (0xa0) in the default ISO 8859-1 characterset.
