PHP - for loop
A FOR loop is very similar to a
WHILE loop in that it continues to
process a block of code until a
statement becomes false, however
everything is defined in a single
line. The basic structure for a
FOR loop is:
for ( start; conditional;
increment) { code to execute; }
Let's go back to our first
example using the WHILE loop,
where we printed out the numbers 1
through 10 and do the same thing
using a FOR loop.
<?php
for ($num=1; $num <= 10;
$num++ )
{
print $num . " ";
}
?> |
The FOR loop can also be used
in conjunction with a conditional,
just like we did with the WHILE
loop:
<?php
for ($num=1; $num <= 10;
$num++ )
{
if ($num < 5)
{
print $num . " is less than 5
<br>";
}
else
{
print $num . " is not less
than 5 <br>";
}
}
?> |
