addErrors()

static SimpleSAML\XML\Errors::addErrors ( )

staticprivate

Append current XML errors to the current stack level.

Definition at line 34 of file Errors.php.

    {
        $currentErrors = libxml_get_errors();
        libxml_clear_errors();

        $level = count(self::$errorStack) - 1;
        self::$errorStack[$level] = array_merge(self::$errorStack[$level], $currentErrors);
    }

begin()

static SimpleSAML\XML\Errors::begin ( )

static

Start error logging.

A call to this function will begin a new error logging context. Every call must have a corresponding call to end().

    }

formatErrors()

static SimpleSAML\XML\Errors::formatErrors (   $errors )

static

Format a list of errors as a string.

This fucntion takes an array of LibXMLError objects and creates a string with all the errors. Each error will be separated by a newline, and the string will end with a newline-character.

Parameters

array

An array of errors.

Returns

string A string representing the errors. An empty string will be returned if there were no errors in the array.
