Seems behaviour changed from PHP4 to PHP5.
[EMAIL PROTECTED]:~$ php -r 'function f() {
var_dump(array_keys(array_shift(debug_backtrace()))); } f(1,3);'
array(4) {
[0]=>
string(4) "file"
[1]=>
string(4) "line"
[2]=>
string(8) "function"
[3]=>
string(4) "args"
}
[EMAIL PROTECTED]:~$ php5 -r 'function f() {
var_dump(array_keys(array_shift(debug_backtrace()))); } f(1,3);'
array(3) {
[0]=>
string(4) "file"
[1]=>
string(4) "line"
[2]=>
string(8) "function"
}
Note that if you join() the result of array_keys the args argument disappears in php4
as well...
This is not mentioned in the changelog, afaik. Maybe it should be?
