The strval function is used to convert a variable into a string type. Its syntax is:

strval($variable)

For example:

$num = 123;
$str = strval($num);
echo $str; // 输出为 "123"

This function is very useful for converting variables of other types to strings, such as converting numbers to strings for string concatenation operations.
