PHP - For Loop
The for loop is simply a while loop with a bit more code added to it. The common tasks that are covered by a for loop are:- Set a counter variable to some initial value.
- Check to see if the conditional statement is true.
- Execute the code within the loop.
- Increment a counter at the end of each iteration through the loop.
For Loop Example
Let us take the example from the while loop lesson and see how it could be done in a for loop. The basic structure of the for loop is as follows:Pseudo PHP Code:
for ( initialize a counter; conditional statement; increment a counter){ do this code; }
Here is the example of the brush prices done with a for loop .
PHP Code:
$brush_price = 5; echo "<table border=\"1\" align=\"center\">"; echo "<tr><th>Quantity</th>"; echo "<th>Price</th></tr>"; for ( $counter = 10; $counter <= 100; $counter += 10) { echo "<tr><td>"; echo $counter; echo "</td><td>"; echo $brush_price * $counter; echo "</td></tr>"; } echo "</table>";
Display:
Quantity | Price |
---|---|
10 | 50 |
20 | 100 |
30 | 150 |
40 | 200 |
50 | 250 |
60 | 300 |
70 | 350 |
80 | 400 |
90 | 450 |
100 | 500 |
