Type Conversion

Conversion casts turn text into numbers or values back into text.

<?php
$raw = ;
$value = (int) $raw;
$doubled = $value * 2;
$label = (string) $doubled . " points";

echo "raw=" . $raw . "\n";
echo "doubled=" . $doubled . "\n";
echo $label . "\n";

<?php
$raw = ;
$value = (int) $raw;
$doubled = $value * 2;
$label = (string) $doubled . " points";

echo "raw=" . $raw . "\n";
echo "doubled=" . $doubled . "\n";
echo $label . "\n";

<?php
$raw = ;
$value = (int) $raw;
$doubled = $value * 2;
$label = (string) $doubled . " points";

echo "raw=" . $raw . "\n";
echo "doubled=" . $doubled . "\n";
echo $label . "\n";

integer cast `(int)` converts numeric text into an integer that arithmetic can use.
