What is the purpose of the strval function in PHP?
The strval function converts a variable into a string type. It can convert variables of types such as integers, floating points, booleans, and others into strings. For example:
$var = 123;
$str = strval($var);
echo $str; // 输出：'123'
Note: The strval function can only convert scalar variables; if an array or object is passed in, it will return an empty string.
