I’ve just decided to venture off into PHP land for fun and to learn, reading that php is loosely typed and that $var’s can be reused is this true that the code below will pose no problem?
$x = 996;
$x = mysql_query("SELECT aString FROM table1");
the variable x will stored as an int datatype with 996, then after the second line it will stored as a string datatype with the string from the query?
There wont be any casting errors?
You are correct; that’s the definition of being “loosely typed”. However, that may not be the best practice.
