对我来说，debug_backtrace达到了内存限制，我想在生产中使用它来记录和发送发生的错误。

相反，我发现这个解决方案非常有效!

// Make a new exception at the point you want to trace, and trace it!
$e = new Exception;
var_dump($e->getTraceAsString());

// Outputs the following 
#2 /usr/share/php/PHPUnit/Framework/TestCase.php(626): SeriesHelperTest->setUp()
#3 /usr/share/php/PHPUnit/Framework/TestResult.php(666): PHPUnit_Framework_TestCase->runBare()
#4 /usr/share/php/PHPUnit/Framework/TestCase.php(576): PHPUnit_Framework_TestResult->run(Object(SeriesHelperTest))
#5 /usr/share/php/PHPUnit/Framework/TestSuite.php(757): PHPUnit_Framework_TestCase->run(Object(PHPUnit_Framework_TestResult))
#6 /usr/share/php/PHPUnit/Framework/TestSuite.php(733): PHPUnit_Framework_TestSuite->runTest(Object(SeriesHelperTest), Object(PHPUnit_Framework_TestResult))
#7 /usr/share/php/PHPUnit/TextUI/TestRunner.php(305): PHPUnit_Framework_TestSuite->run(Object(PHPUnit_Framework_TestResult), false, Array, Array, false)
#8 /usr/share/php/PHPUnit/TextUI/Command.php(188): PHPUnit_TextUI_TestRunner->doRun(Object(PHPUnit_Framework_TestSuite), Array)
#9 /usr/share/php/PHPUnit/TextUI/Command.php(129): PHPUnit_TextUI_Command->run(Array, true)
#10 /usr/bin/phpunit(53): PHPUnit_TextUI_Command::main()
#11 {main}"

我所见过的这个问题的最佳答案是:

list(, $caller) = debug_backtrace(false);

简洁明了

获取父函数名最简单的方法是:

$caller = next(debug_backtrace())['function'];

你也可以使用php异常提供的信息，这是一个优雅的解决方案:

function GetCallingMethodName(){
    $e = new Exception();
    $trace = $e->getTrace();
    //position 0 would be the line that called this function so we ignore it
    $last_call = $trace[1];
    print_r($last_call);
}

function firstCall($a, $b){
    theCall($a, $b);
}

function theCall($a, $b){
    GetCallingMethodName();
}

firstCall('lucia', 'php');

你会得到这个…(瞧!)

Array
(
    [file] => /home/lufigueroa/Desktop/test.php
    [line] => 12
    [function] => theCall
    [args] => Array
        (
            [0] => lucia
            [1] => php
        )

)

debug_backtrace()函数是知道这一点的唯一方法，如果你很懒，这是你应该自己编写GetCallingMethodName()的另一个原因。战胜懒惰!: D
