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 on 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 either adding a global try catch for the entire application

try {
   ...
} catch (Throwable $e)
   // var_dump($e.$e->getTrace()); // for the local environment
   error_log($e.$e->getTrace()); // for the live environment
}

or by adding a global Exception handler to your application.

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).

More information is available here or in the corresponding RFC.
