php - Use contents of string variable to call function -


i have following piece of code

copy($source, $target);

i use

move_uploaded_file($source, $target);

to prevent code reuse, want pass copy , move_uploaded_file in via variable.

if variable $var = "copy";, putting $var($source, $target);, doesn't seem work.

are there special characters must surround $var?

thanks.

the correct syntax $var (variable functions), code should work.

but please don't that, write code in straightforward , readable manner. there are legitimate use cases technique, not 1 of them.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
