Answer 1

A loosely typed language refers to the syntax of the language. The syntax is not as strict, as opposed to Java or C, but is loose, because it does not require you to declare variable types. Because of this, a PHP can contain any type of data in a single variable, whereas in Java, it can only contain the type it was defined as.

PHP:
$myVar = 5; //legal
$myVar = "Hello World!"; //Also legal

Java:
int myVar; //type definition
myVar = 5; //legal
myVar = "Hello World!"; //NOT legal. Won't compile
