The following are examples of php_syscalls.d.

This is a simple script to count executed PHP functions and system calls.

Here it traces an example program, Code/Php/func_abc.php

# php_syscalls.d

Tracing... Hit Ctrl-C to end.

^C

PID FILE TYPE NAME COUNT

18419 func_abc.php func func_a 1

18419 func_abc.php func func_b 1

18419 func_abc.php func func_c 1

18419 func_abc.php func sleep 3

18419 httpd syscall nanosleep 3

While tracing, four functions were called - func_a(), func_b(), func_c(), and

sleep. There were also three instances of the system call nanosleep().

This script can provide an insight to how a PHP application is interacting

with the system, by providing both application function calls and system calls

in the same output.
