From PHP.net :

bool settype ( mixed &$var , string $type )

Parameters

var : The variable being converted. type : Possibles values of type are:

• "boolean" (or, since PHP 4.2.0, "bool")
• "integer" (or, since PHP 4.2.0, "int")
• "float" (only possible since PHP 4.2.0, for older versions use the deprecated variant "double")
• "string"
• "array"
• "object"
• "null" (since PHP 4.2.0)
