PHP4 Practical Application Experience (4)_PHP Tutorial
Author: Sun Movement
In addition to the "if" statement, PHP also provides the "if-else" structure, which is used to define the PHP code that is executed when the condition in the statement is described as a "false" value.
The "if-else" structure is used as follows:
------------------------- -------------------------------------------------- -----
if (condition)
{
do this!
}
else
{
do this!
}
--- -------------------------------------------------- --------------------------
You will see that this structure can be used to greatly simplify the example in the previous article - Instead of two separate "if" statements nested, we can mix them in a single "if-else" statement:
