+ * php_syscalls.d - count PHP function calls and syscalls using DTrace.
+ *                  Written for the PHP DTrace provider.
+ *
+ * This traces syscalls that occured during a PHP function call.
+ *
+ * $Id: php_syscalls.d 53 2007-09-24 04:58:38Z brendan $
+ *
+ * USAGE: php_syscalls.d 	# hit Ctrl-C to end
+ *
+ * FIELDS:
+ *		PID		Process ID
+ *		FILE		Filename of the PHP program
+ *		TYPE		Type of call (func/syscall)
+ *		NAME		Name of call
+ *		COUNT		Number of calls during sample
+ *
+ * Filename and function names are printed if available.
+ * The filename for syscalls may be printed as "php", if the program
+ * was invoked using the form "php filename" rather than running the
+ * program with an interpreter line.
