funclist.txt size 44686 funcsummary.txt size 267625 quickref.txt size 137820
Note
Notă: Această funcţie nu va lucra cu fişiere la distanţă, deoarece fişierul care trebuie să fie examinat trebuie să fie accesibil prin intermediul sistemului de fişiere al serverului.
Notă: This function isn't available on some systems (e.g. old Sun OS).
Notă: The GLOB_BRACE flag is not available on some non GNU systems, like Solaris.
