Answer Sheet

1	D	PHP previously stood for Personal Home Page now stands for Hypertext Preprocessor.
2	C
3	C	Every section of PHP code starts and ends by turning on and off PHP tags to let the server know that it needs to execute the PHP in between them.
4	B	Any of the above editors can be used to type php code and run it.
5	D	To run PHP code you need to have PHP and a web server, both IIS and Apache are web servers.You can choose either one according to your platform.
6	D	A variable can’t start with a number. Also $this is a special variable that can’t be assigned, but $This can be assigned
7	C	The $bar = &$foo; line will reference $foo via $bar.
8	B	echo(), print() and printf() all three can be used to output a statement onto the screen. The sprintf() statement is functionally identical to printf() except that the output is assigned to a string rather than rendered to the browser.
9	A	($i > ++$i) evaluates to 0 but -1 makes it enters the loop and prints i which is 0.
10	C	Use of undefined constant red.
11	C	+ does not return 1 if the variables are equal.
12	A	Anything starting from 0 is evaluated as an octal.
13	C	The array_merge() function merges one or more arrays into one array.
14	B
15	D	The array_fill() function fills an array with values.

24	D	The array_shift() function removes the first element from an array, and returns the value of the removed element.
25	B	Within flat files(files), within volatile memory(mm), using the SQLite database(sqlite), or through user defined functions(user).
26	D	Keyword like IF cannot be used as constant names.
27	C	When the format is E the timezone is identified and returned…example America/New_York.

38	C	+ operator does not join both the strings.
39	C	The array_change_key_case() function changes all keys in an array to lowercase or uppercase.
40	B	While condition always gives 1.
41	B	Constants do not need a $ before them, they are referenced by their variable names itself.
42	D	It has to be $color1 = red; and $color2 = green; therefore the error.

44	B	The getlastmod() function returns the value of the pages Last Modified header or FALSE in the case of an error.
45	D	+ just returns the numeric value even though it is inside double quotes.
46	A	As it is || operator the second expression is not evaluated till i becomes 1 then it goes into a loop.
47	B	The directive which determines this is session.cache_expire.
48	A	echo constant(x) output x, and x here is the concatenation of GREETING_ and $changing variable with. operator.
49	A	The lifetime is specified in seconds, so if the cookie should live 1 hour, this directive should be set to 3600.

54	D	The dateTime() method is class constructor. You can set the date either at the time of instantiation or later by using a variety of mutators.
55	A	Day of month, with leading zero is represented by D; Daylight saving time by I; Day of month, without zeros by j.
56	D	The directive session.cookie_domain determines the domain for which the cookie is valid.
