fopen - PHP adding $ signs into strings without it being a variable? -

-

this question has answer here:

i'm making setup page people can write database login etc , create config.php file on webserver info can't write

$file = fopen("config.php", "w"); fwrite($file, "$dbname = $dbname");

i tried

$file = fopen("config.php", "w"); fwrite($file, "$" . "dbname = $dbname");

but doesn't work either.

any way store php variable in file write using php?

as php document says

if string enclosed in double-quotes ("), php interpret following escape sequences special characters: \$ dollar sign

http://php.net/manual/en/language.types.string.php

so if want use $ in double-quotes strings use \$ instead of $.

or use single quotes

ios - Why must I define variables twice in the Header file? -

why must define variables twice in header file? differences there between these variables? the first definition here: @interface mycontroller: uiviewcontroller { nsinteger selectedindex; } the second definition here: @property (nonatomic) nsinteger selectedindex; what you're seeing required in earlier versions of objective-c, isn't more. in first versions of objective-c used next until new runtime introduced (with objective-c 2.0 on mac os x), instance variables had declared part of class's structure in @interface . reason if subclassed class, compiler needed know instance variable layout of class see @ offset put subclass's instance variables. when properties introduced, synthesized properties had "backed" instance variable in class's structure. therefore had declare both instance variable , property. all of above no longer true. newer objective-c less fragile in way looks instance variable...
