Biske94 posted a topic in General ProgrammingWhat does mean that variable is set or not set? (in PHP or general) Does that means: // no var declared $var; $var = 'Some fancy string'; $var = ""; //(empty string) I dont know all fancy terms, but I do know when variable is defined, declared and all that, but I dont know what variable is set means. Thanks in advance, nerdz!
