The function is used to return the value of the statement.<\/p>\n

Example<\/strong><\/p>\n

[php]<?php
\nfunction sum($x, $y) {
\n $z = $x + $y;
\n return $z;
\n}<\/p>\n

echo "5 + 10 = " . sum(5, 10) . "<br>";
\necho "7 + 13 = " . sum(7, 13) . "<br>";
\necho "2 + 4 = " . sum(2, 4);
\n?>[\/php]<\/p>\n

In the above function statement, first, we have to add the two variables $x<\/code> and $y<\/code> and return the sum in the return value $z<\/code>. We will be using the return value in the echo statement.<\/p>\n

In the echo statement, we are asking php script to sum the values and return the variable $z<\/code>.<\/p>\n

The above statement will generate the following result.<\/p>\n

5 + 10 = 15
\n7 + 13 = 20
\n2 + 4 = 6<\/code><\/p>\n","protected":false},"excerpt":{"rendered":"
