\nThe first thing that needs to be done is to eliminate the se of the removed extensions. The PHP migration<\/a> document can offer quite a few alternatives for these removed extensions.<\/p>\n\n

\nFor example:
\n<?php
\nvar_dump(is_numeric(\u201c0x123\u201d));
\n?>\u00a0\u00a0 The output of the example mentioned above in PHP 7 is:bool(false)<\/li>\n
\nEarlier, when 0 was used as the divisor for either the divide(\/) or modulus(%) operators, and E_WARNING would be emitted and false would be returned. It has now changed to the divide operator returning a float as either +INF, -INF, or NAN. The modulus operator E_WARNING has been removed and will throw a DivisionByZeroError exception.<\/li>\n<\/ul>\n
