PHP Debug_backtrace () function

The PHP debug_backtrace () function generates a backtrace

the function returns an associative array .

Here are the elements that might be returned

Functions string Current function name

Line	Integer	The current line number
File	String	The current file name
Object	Object	Current Object
Type	String	Current invocation type, possible invocation: return: "-"-Method call Returns: "::"-static method call returns Nothing-function call
Args	Array	If the function parameter is listed in the function. If the referenced file name is listed in the referenced files

For Example One:

Class hello{        private    $var;        Public     $var 2;        protected  $var 3;    Public function __construct ($var, $var 2, $var 3) {            $this->var= $var;            $this->var2= $var 2;            $this->var3= $var 3;        }    } function test (Hello $hello) {        echo "Hi This is a test function".
";        Print_r (Debug_backtrace ());} $hello 2=new Hello (' A ', ' B ', ' C '); Test ($hello 2);

The example one outputs the following results:

Hi This is a test function
Array ([0] = = Array (
[File] = D:\www\MyProjecttest\index4.php
[Line] = 52
[Function] = Test
[Args] = Array ([0] = = Hello Object ([var:Hello:private] = A [VAR2] = B [var3:protected] = C))))

Note: Only four parameters are output here: File,line,function,args;

For Example:

Class hello{        private    $var;        Public     $var 2;        protected  $var 3;   Public function __construct ($var, $var 2, $var 3) {      $this->var= $var;      $this->var2= $var 2;      $this->var3= $var 3; }    function Test (Hello $hello) {       echo "Hi This is a test function".
";       Print_r (Debug_backtrace ());}   } $hello 2=new Hello (' A ', ' B ', ' C '); $hello 2->test ($hello 2);

The result of the example output is as follows:

Hi This is a test function
Array ([0] = = Array (
[File] = D:\www\MyProjecttest\index4.php
[Line] = 54
[Function] = Test
[Class] = Hello
[Object] = Hello object ([var:Hello:private] = A [VAR2] = B [var3:protected] + C)
[Type] =
[Args] = Array ([0] = = Hello Object ([var:Hello:private] = A [VAR2] = B [var3:protected] = C))))

Note: In this all parameters are output, respectively: File,line,function,class,object,type,args;
