缩短“If - Then - Else”? [英] Shortened "If - Then - Else"?
问题描述
嘿所有,
只是想知道在PHP中是否有缩写的If - Then - Else
格式,就像在JavaScript。
JavaScript允许使用以下格式的缩写版本:
([CONDITION]?[RESULT_THEN]:[RESULT_ELSE])
这种格式能够包含在
声明中的等号后面,例如:
var foo =(field1 =='' content''?''bar'':''foo'');
任何帮助都会受到赞赏 - 我只是想减少
的数量
详细和嵌套如果'... ...
谢谢
卢克

使用源Luke;)我提供文档。
是的,您可以使用简短形式,与其他语言一样,简短
表单是表达式,而长表单是声明。

Hey All,
Just wondering whether there is an abbreviated "If - Then - Else"
format in PHP, much like that possible in JavaScript.
JavaScript allows an abbreviated version in the following format:
( [CONDITION]? [RESULT_THEN]: [RESULT_ELSE] )
This format is able to be included after the equal sign in a
declaration, such as:
var foo = ( field1==''content''? ''bar'': ''foo'' );
Any help would be appreciated - I''m just trying to reduce the number of
verbose and nested If''s...
Thanks
Luke

Have you looked in the manual yet?

Use the source Luke ;) oups I ment documentation.
yes you can use short form, and in the same way as in other languages, short
form is expression while long one is statement.

More specifically:

I''ve always wondered how people manage to learn a programming language
without even looking at the documentation :)
