php - Checking if file exists -


i have piece of code checks whether image exists in file system , if so, displays it.

if (file_exists(realpath(dirname(__file__) . $user_image))) {     echo '<img src="'.$user_image.'" />'; }  else {     echo "no image set";     }

if echo $user_image out, copy , paste link browser, image there. however, here, 'no image set' being reached.

the $user_image contents http://localhost:8888/mvc/images/users/1.jpg

some of these functions not needed?

any ideas? broken code or better way of doing (that works!)?

beside @hek2mgl answer think correct, think should switch is_file() instead of file_exists(). also, can go bit further like:

if(is_file(dirname(__file__). '/' . $user_image) && false !== @getimagesize(dirname(__file__) . '/'. $user_image)) {    // image fine } else {    // isn't }

l.e:1
oh great, telling $user_image contains? couldn't start, you? have to:

$userimagepath = parse_url($user_image, php_url_path); $fullpath = dirname(__file__) . ' / ' . $userimagepath; if($userimagepath && is_file($fullpath) && false !== @getimagesize($fullpath)) {    // valid }else {    // isn't }

l.e: 2 also, storing entire url not practice, happens when switch domain names? try store relative path, /blah/images/image.png instead of http://locathost/blah/images/image.png

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).
