Below, there are some patterns related to star, number and alphabets that are also asked in interview to test your logic. Some below:
<?php
for($i = 1;$i<=5;$i++)
{
for($j=1;$j<=$i;$j++)
{
echo "*";
}
echo "<br>";
}
?>
<?php
for($i = 5;$i>=1;$i--)
{
for($j=0;$j<$i;$j++)
{
echo "*";
}
echo "<br>";
}
?>
<?php
for($i = 1;$i<=5;$i++)
{
for($j=1;$j<=$i;$j++)
{
echo $i;
}
echo "<br>";
}
?>
<?php
$k = 1;
for($i = 1; $i<=4; $i++)
{
for($j=1; $j<=$i; $j++)
{
echo $k." "; $k++;
}
echo "<br>";
}
?>
<?php
for($i = 1; $i<=4; $i++)
{
for($j=4; $j>=$i; $j--)
{
echo " ";
}
for($k=1; $k<=$i; $k++)
{
echo $k." ";
}
for($m=($i-1); $m>=1; $m--)
{
echo $m." ";
}
echo "<br>";
}
?>
<?php
for($i = 1; $i<=4; $i++)
{
for($j=4; $j>=($i + 1); $j--)
{
echo " ";
}
for($k=1; $k<=$i; $k++)
{
echo "*"." ";
}
for($m=2; $m<=$i; $m++)
{
echo "*"." ";
}
echo "<br>";
}
?>
