Answer 1

You should put all text that should keep form and not whitespace trimmed in between a <pre/> tag
<pre><?php
for($i=1; $i<=5; $i++){
for($j=5; $j>$i; $j--){
echo " ";
}
echo "*";
for($j=1; $j<($i-1)*2; $j++){
echo " ";
}
if($i==1)echo "<br>";
else echo "*<br>";
}
for($i=4; $i>=1; $i--){
for($j=5; $j>$i; $j--){
echo " ";
}
echo "*";
for($j=1; $j<($i-1)*2; $j++){
echo " ";
}
if($i==1)echo "<br>";
else echo "*<br>";
} ?></pre>
Note: if your target is console and PHP-CLI, don't put the <pre/> tag, omit the end of PHP tag (?>) and replace all <br/> tags with \n.

Thanks to all of you guys. I add <pre> tag before code and also change <br> tag with \n and now it is work. Thanks again. Have a nice day guys..

Try this...
function printPattern($n)
{
$k = 0;
// Print upper triangle
for ($i = 1; $i <= $n; $i++)
{
// Print spaces
for ($j = 1; $j <= $n - $i; $j++)
{
echo " ";
}
// Print #
while ($k != (2 * $i - 1))
{
if ($k == 0 or $k == 2 * $i - 2)
echo "*";
else
echo " ";
$k++;
}
$k = 0;
// move to next row
echo "\n";
}
$n--;
// Print lower triangle
for ($i = $n; $i >= 1; $i--)
{
// Print spaces
for ($j = 0; $j <= $n - $i; $j++)
{
echo " ";
}
// Print #
$k = 0;
while ($k != (2 * $i - 1))
{
if ($k == 0 or $k == 2 * $i - 2)
echo "*";
else
echo " ";
$k++;
}
echo "\n";
}
}
// Driver Code
$n = 6;
printPattern($n);
// This Code is contributed by mits
