php - Checking for string match with a MySQL query -


i trying grab rows of data data table, 1 word matches word within text in column 'story'.

table structure:

post_id | user_id | story ---------------------------------- 1       | 1       | hello world what's up? 2       | 4       | hello guys! 3       | 7       | working on shareit.me!

for example:

i want grab of posts containing word hello (i looking case-insensitive).

how can this?

here have done far:

// keyword! use variable $filter_tag in query! $filter_tag= $_get['tag'];  //query getting users' posts containing select tag  $query_posts= "select * posts user_id= '$user_id' order post_id  desc";  $result_posts= mysqli_query($connect, $query_posts);

thanks!

 $query_posts= "select * posts user_id= '$user_id' , story '%$filter_tag%' order post_id      desc";

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).
