スタックトレースを取得するために使用getTraceAsString()していますが、何らかの理由で文字列が切り捨てられています。

たとえば、例外がスローされ、次のコマンドを使用して文字列をログに記録します。

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

印刷される文字列は次のとおりです。

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

文字列全体を印刷するにはどうすればよいですか？

この関数を作成して、切り捨てられた文字列のないスタック トレースを返します。

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%s(%s)\n",
            $count,
            $frame['file'],
            $frame['line'],
            isset($frame['class']) ? $frame['class'] : '',
            isset($frame['type']) ? $frame['type'] : '', // "->" or "::"
            $frame['function'],
            $args
        );
        $count++;
    }
    return $rtn;
}

That solution is good but in my case it threw an error because my trace has internal functions in it. I added a few lines of code to check for that so the trace functions still works.

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;
}

php.ini 設定の変更はlog_errors_max_len役に立ちますか?

また、メッセージは出力中にのみ切り捨てられることに注意してください。 $exception->getMessage() を呼び出すと、元のエラー メッセージを取得できます。

例外を再スローする場合、前の例外を 3 番目の引数として指定できます。こうすることで、例外トレースを連鎖させることができます。

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;
}
