Question

我正在使用getTraceAsString()来获取堆栈跟踪但由于某种原因字符串被截断。

示例，抛出异常并使用以下命令记录字符串：

catch (SoapFault $e) {
error_log( $e->getTraceAsString() )
}

打印出的字符串是：

＃0 C：\ Somedirectory \ Somedirectory \ Somedirectory \ Somedir \ SomeScript.php（10）：SoapClient-＆gt; SoapClient（'http://www.ex ...'）

如何获取要打印的完整字符串？

Answer 1

我创建了这个函数来返回没有截断字符串的堆栈跟踪：

function getExceptionTraceAsString($exception) {
    $rtn = "";
    $count = 0;
    foreach ($exception->getTrace() as $frame) {
        $args = "";
        if (isset($frame['args'])) {
            $args = array();
            foreach ($frame['args'] as $arg) {
                if (is_string($arg)) {
                    $args[] = "'" . $arg . "'";
                } elseif (is_array($arg)) {
                    $args[] = "Array";
                } elseif (is_null($arg)) {
                    $args[] = 'NULL';
                } elseif (is_bool($arg)) {
                    $args[] = ($arg) ? "true" : "false";
                } elseif (is_object($arg)) {
                    $args[] = get_class($arg);
                } elseif (is_resource($arg)) {
                    $args[] = get_resource_type($arg);
                } else {
                    $args[] = $arg;
                }   
            }   
            $args = join(", ", $args);
        }
        $rtn .= sprintf( "#%s %s(%s): %s(%s)\n",
                                 $count,
                                 $frame['file'],
                                 $frame['line'],
                                 $frame['function'],
                                 $args );
        $count++;
    }
    return $rtn;
}

或者，您可以编辑截断输出的php源：https://github.com/php/php-src/blob/master/Zend/zend_exceptions.c#L392

一些更好的版本https://stackoverflow.com/a/6076667/194508在这里https://gist.github.com/1437966添加了要输出的类。

Answer 3

这个解决方案很好但是在我的情况下它会抛出一个错误，因为我的跟踪中有内部函数。我添加了几行代码来检查，以便跟踪功能仍然有效。

function getExceptionTraceAsString($exception) {
    $rtn = "";
    $count = 0;
    foreach ($exception->getTrace() as $frame) {


        $args = "";
        if (isset($frame['args'])) {
            $args = array();
            foreach ($frame['args'] as $arg) {
                if (is_string($arg)) {
                    $args[] = "'" . $arg . "'";
                } elseif (is_array($arg)) {
                    $args[] = "Array";
                } elseif (is_null($arg)) {
                    $args[] = 'NULL';
                } elseif (is_bool($arg)) {
                    $args[] = ($arg) ? "true" : "false";
                } elseif (is_object($arg)) {
                    $args[] = get_class($arg);
                } elseif (is_resource($arg)) {
                    $args[] = get_resource_type($arg);
                } else {
                    $args[] = $arg;
                }
            }
            $args = join(", ", $args);
        }
        $current_file = "[internal function]";
        if(isset($frame['file']))
        {
            $current_file = $frame['file'];
        }
        $current_line = "";
        if(isset($frame['line']))
        {
            $current_line = $frame['line'];
        }
        $rtn .= sprintf( "#%s %s(%s): %s(%s)\n",
            $count,
            $current_file,
            $current_line,
            $frame['function'],
            $args );
        $count++;
    }
    return $rtn;
}

Answer 4

更改php.ini设置log_errors_max_len会有帮助吗？

此外，请注意，邮件仅在输出期间被截断，您仍然可以通过调用$ exception-＆gt; getMessage（）

来获取原始错误消息

Answer 5

Ernest Vogelsinger在https://www.php.net/manual/exception.gettraceasstring.php#114980也提供了优秀的Permission denied配方，它支持链式异常，并以类似Java的方式进行格式化。

以下是他对php.net的评论直接比较：

Exception :: getTraceAsString：

jTraceEx

jTraceEx：

#0 /var/htdocs/websites/sbdevel/public/index.php(70): seabird\test\C->exc()
#1 /var/htdocs/websites/sbdevel/public/index.php(85): seabird\test\C->doexc()
#2 /var/htdocs/websites/sbdevel/public/index.php(89): seabird\test\fail2()
#3 /var/htdocs/websites/sbdevel/public/index.php(93): seabird\test\fail1()
#4 {main}

Answer 6

您可以使用

打印回溯

MiddleName   LastName
john            .
james        phillips
Mary            .

The procedure should then make it:
MiddleName   LastName
             john 
james        phillips
             Mary

它不会截断。

示例打印为

debug_print_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS);

Answer 7

在抛出异常的情况下，可以提供先前的异常作为第三个参数。这样，可以链接“异常”跟踪。

try  {
    f('123');
} catch(Throwable $e){
    var_dump($e);
}

function f($arg){
    if(is_string($arg)){
        try {
            g($arg);
        } catch(UnexpectedValueException $e) {
            // Supply a third argument to pass the previous Exception.
            throw new RuntimeException('Error in function g()', $e->getCode(), $e);
        } catch(Throwable $e) {
            // Supply a third argument to pass the previous Exception.
            throw new RuntimeException('Unkown Error in function g()', $e->getCode(), $e);
        }   
    }   
}

function g($string){
    if(strlen($string) < 6){
        try {
            h($string);
        } catch(UnexpectedValueException $e) {
            throw new UnexpectedValueException('String is smaller then 6', $e->getCode(), $e);
        }
    }
    return $string;
}

function h($string){
    if(strlen($string) < 4){
        throw new UnexpectedValueException('String is smaller then 4');
    }
    return $string;
}

输出：

如果你可以使用var_dump()，那么一个简单的解决方案就是：

try {
   ...
} catch (Exception $e)
   var_dump($e->getTrace());
}
