HEREDOC INPUT

<?php
$mystring = <<<EOT
Any text within the Heredoc commands will print out words. You can use "double" and 'single' quotes as well as \$variables--still need to escape the dollar sign. Also useful for dingbat ttf files that use quotes and other symbols to call them. Use for nested variables in gradtable art. Must have no spaces after the letters EOT (end of text);
EOT;
echo $mystring;
?>

NOTE: The total codes for the Heredoc is:
$generic = <<<EOT
words words words
EOT;

HEREDOC OUTPUT

Any text within the Heredoc commands will print out words. You can use "double" and 'single' quotes as well as $variables--still need to escape the dollar sign. Also useful for dingbat ttf files that use quotes and other symbols to call them. Use for nested tables in gradtable art. Must have no spaces after EOT codes;

WHILE LOOP INPUT
While (string relates to string/is true) do this.
++$x; is the same as writing $x = $x + 1;

$times = 5;
echo "<table border=\"1\" align=\"center\">";
$x = 0;
while ($x < $times)
{
echo "<tr><td>";
echo "Hello World";
++$x;
echo "</td></tr>";
}
echo "</table>";
?>

WHILE LOOP OUTPUT

Hello World

WHILE LOOP INPUT
Same loop as above using a gradtable.

<?php
$times = 5;
echo "<table border=\"0\" cellspacing=\"0\" align=\"center\">";
$x = 0;
while ($x < $times)
{
echo "<tr><td bgcolor=\"black\" gradcolor=\"red\" width=\"150\" height=\"20\" gradangle=\"90\"></td><td bgcolor=\"black\" gradcolor=\"red\" width=\"150\" height=\"20\" gradangle=\"-90\">";
++$x;
echo "</td></tr>";

WHILE LOOP OUTPUT

WHILE LOOP INPUT
While (conditional statement {do this}

<?php
$item_price = 5;
$counter = 10;
echo "<table border=\"1\" align=\"center\">";
echo "<tr><<h>Quantity</th>";
echo "<th>Price</th></tr>";
while ( $counter <= 50 ) {
echo "<tr><td>";
echo $counter;
echo "</td><td>";
echo $item_price * $counter;
echo "</td></tr>";
$counter = $counter + 10;

Quantity	Price
10	50
20	100
30	150
40	200
50	250

WHILE LOOP INPUT
Gradtable shows that second column is not a true calculator
