PHP - while loop
In PHP there are several
different types of loops.
Basically what a loop does is
evaluate a statement as true
or false. If it is true it
executes some code and then
alters the original statement
and starts all over again by
re-evaluating it. It continues
to loop through the code like
this until the statement
becomes false.
Basically what this does is: while
a number is greater than or equal
to 10 it prints the number. The ++
adds one to the number, however
this could also be phrased as $num
= $num + 1; Once the number
becomes greater than 10, in our
case it becomes 11, then it stops
executing the code within the
{brackets}
Below is an example of how you
can combine a loop with a
conditional
<?php
$num = 1;
while ( $num <=10 )
{
if ($num < 5)
{
print $num . " is less than 5
<br>";
}
else
{
print $num . " is not less
than 5 <br>";
}
$num++;
}
?> |
