Expand PHP Stack Trace Arguments

On a stack trace returned from a PHP application in development, long string arguments to a function are truncated when display o开发者_高级运维n the error page:

Abstract.php(238): Zend_Db_Adapter_Abstract->query('INSERT INTO "tb...', Array)

How can I expand the query argument so the full text is visible? The server is running PHP 5.3.3.

Use debug_backtrace instead. It will give you the whole trace and doesn't trim arguments as far as I know.

On a second thought: You might get away with it by using

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

instead.

Starting with PHP 8.0 it is possible to actually raise the limit at which arguments will be truncated.

You can change the newly introduced php.ini setting zend.exception_string_param_max_len and set it to any value between 0 and 1000000, the default being 15.

This only affects stack traces generated using getTraceAsString() or by casting an exception to a string (e.g., by printing it).
