In all versions of PHP   between 5.0.x and 5.1.x, the handling of integer values was very strict and   would reject non-well formed numeric values when a PHP function expected an   integer. These checks have now been relaxed to support non-well formed   numeric strings such as &quot; 123&quot; and &quot;123 &quot;, and will no longer fail as they   did under PHP 5.0.x. However, to promote code safety and input validation,   PHP functions will now emit an <b><tt>E_NOTICE</tt></b> when such   strings are passed as integers.  </p> </div><hr /><div style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="migration51.reading.html">Reading []</a></div> <div class="next" style="text-align: right; float: right;"><a href="migration51.oop.html">Class and object changes</a></div> <div class="up"><a href="migration51.html">Migrating from PHP 5.0.x to PHP 5.1.x</a></div> <div class="home"><a href="index.html">PHP Manual</a></div></div></body></html>
