Sprintf Format Compilation
++++++++++++++++++++++++++

  The `sprintf() <https://www.php.net/sprintf>`_ format used yields an `error <https://www.php.net/error>`_. A format is a ``%`` pourcent character, followed by a letter. 

Some letters are not allowed: ``a, i, j, k, l, m, n, p, q, r, t, v, w, y, z, A, B, C, D, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, Y, Z``.

This applies to `printf() <https://www.php.net/printf>`_, `sprintf() <https://www.php.net/sprintf>`_, `vprintf() <https://www.php.net/vprintf>`_, `vfprintf() <https://www.php.net/vfprintf>`_, `vsprintf() <https://www.php.net/vsprintf>`_, `sscanf() <https://www.php.net/sscanf>`_, `fscanf() <https://www.php.net/fscanf>`_

.. code-block:: php
   
   <?php
   
       printf('\%we3e\\', 123); 
       //Unknown format specifier \w\\
   ?>
