php - Execute a timed command in a time command -


i working php application need check database of users whom has birthday today. through cron job.

now, when users birthday, need send them sms. sms has individual time associated determins when sms should send. lets john , peter has birthday today. peter works 01-09 should sms @ 01 , peter works 08-16 should sms @ 08.

i thinking dynamically creating same amount of cron jbos equals people has birthday on given date. cron jobs send sms appropiate people 1 time , thats it.

my question is, there smarter way this? secondly, if cron job generation idea enough, there way remove individual old cron jobs dont clug cron job list old jobs never run again?

thanks in advance.

if you're worried creating many cron jobs (not sure how many problem on system), why not create 1 cron job @ os level? can call program every 10 minutes or so, , can check if there new people need sent sms.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
