system() & exec()

system()
The system() call also tries to automatically flush the web server’s output buffer after each line of output if PHP is running as a server module.
exec()
則不會flush

遇到的問題是
我的php 透過perl 去執行一些功能
然後perl 回傳 success or false 字串在standard output 上
php再去get 這個字串
success 則print success
給 ajax 來判斷

結果在前端的ajax 一直印出 successsuccess
的字眼
想說怎麼會印兩次….
看了一下手冊才發現這個

之前就想說 php 幹麻沒事有兩個執行CLI 的東西……
仔細看了一下手冊才知道
筆記一下..
