The debug backtrace shows filename and lineno of calling script. In
case function is called from inside internal function (may be as
callback) no filename and lineno may be set.

Description:
------------
In all cases (but the one below one), "file" and "line" indexes are
defined in each frame of the output of debug_backtrace.
But when using call_user_function() or call_user_function_array, "file"
and "line" is not defined for one of the frames.
It would be nice if I could count on file and line always being defined
when using the output of debug_backtrace, thereby avoiding code for
special cases.
For the missing file and line in the example code below, when calling
f() inside call_user_function(), I suggest using the file and line of
the call_user_function() call.
See also bug 38047 and 24405.
Reproduce code:
---------------
<?php
error_reporting(E_ALL | E_STRICT);
function f() {
$a = $b;
var_dump(debug_backtrace());
}
//The backtrace generated here will not have file and line defined
call_user_func("f", Array());
//The backtrace generated here will have file and line defined.
f();
?>
Expected result:
----------------
The frame with index 0 of the first debug_backtrace_call should contain
indexes "file" => "test.php" and "line" => 6
Actual result:
--------------
array(2) {
[0]=>
array(2) {
["function"]=>
string(1) "f"
["args"]=>
array(1) {
[0]=>
&array(0) {
}
}
}
[1]=>
array(4) {
["file"]=>
string(18) "/home/tjk/test.php"
["line"]=>
int(6)
["function"]=>
string(14) "call_user_func"
["args"]=>
array(2) {
[0]=>
&string(1) "f"
[1]=>
&array(0) {
}
}
}
}
array(1) {
[0]=>
array(4) {
["file"]=>
string(18) "/home/tjk/test.php"
["line"]=>
int(8)
["function"]=>
string(1) "f"
["args"]=>
array(0) {
}
}
}
