The multiplication table is also a program question in many interview exams. It tests the logical thinking ability of the PHP interviewer, mainly the understanding and application of algorithms. The following is the PHP code written by the editor in PHP to output the multiplication table. :

<&#63;php
for($i=1;$i<=9;$i++)
{
for($j=1;$j<=$i;$j++)
{
echo “$i*$j=”.$i*$j.' ‘;
}
echo ‘<br />';
}
&#63;>
