PHP uses define to define how constants are used

This article mainly introduces the use of PHP to define constants using define, interested in the reference of friends, I hope to be helpful to everyone.

Specific as follows:

<?php/* * * * * * */* 3rd parameter: * False--sensitive to case (default) * True--insensitive to capitalization * */define ("Pai", 3.14); Define ("name", "Lilei", true); function Testfor ($x) {for  ($a = $x; $a <=12; $a + +) {    echo "is now a $ A point:";    if ($a <9) {      echo "knock Code";      echo name;    } else {      echo "sleeps";      echo pai;    }    echo "<br/>";  } } testfor (10);? >

The results of the operation are as follows:

Now it's 10: Sleep 3.14.
Now it's 11: Sleep 3.14.
Now it's 12: Sleep 3.14.

Summary : The above is the entire content of this article, I hope to be able to help you learn.
