Echo Or Print
+++++++++++++

  Echo and print have the same functional use. <?= and `printf() <https://www.php.net/printf>`_ are also considered in this analysis. 

There seems to be a choice that is not enforced : one form is dominant, (> 90%) while the others are rare. 

The analyzed code has less than 10% of one of the three : for consistency reasons, it is recommended to make them all the same. 

It happens that print, echo or <?= are used depending on coding style and files. One file may be consistently using print, while the others are all using echo.

.. code-block:: php
   
   <?php
   
   echo 'a';
   echo 'b';
   echo 'c';
   echo 'd';
   echo 'e';
   echo 'f';
   echo 'g';
   echo 'h';
   echo 'i';
   echo 'j';
   echo 'k';
   
   // This should probably be written 'echo';
   print 'l';
   
   ?>
