}

3. return $variable or return true

4. If defining: } if calling ;

5. 0

6. Every command must end in ";"

8. Yes

9. There is if.. then in PHP

11. The dollar sign ($)

$something == 0 (integers do not require quotes, strings do)

or
/*

*/

14. visit http://www.php.net/ or http://www.w3schools.com

Answer 2

many tutorials regarding PHP are available on the site http://earlysandwich.com . i personally downloaded many tutorials from them.

Answer 3

some do, some do not. Why do ask? in case you "accompanied up" and did some analyze, you need to verify that merely about 0.5 (of the intense questions, a minimum of) are resolved. sure, it is only a pastime, yet i does no longer say valueless. it is psychological exercising. You get to verify how properly you could tolerate idiots and how a lot you and others recognize.

Answer 4

1) function foo(){/*do stuff*/}

2) foo();

3) function foo(){return 1;}

4) with a }, does not require a return

5) 0

6) yes, all commands require a ;

7) $concat = $str1.$str2;

8) no, if it is a one line if you can just do if(true) foo();

9) if({condition}){/*do stuff*/}

10) elseif({condition}){/*do stuff*/}

11) function foo(& $arg){}

12) $val1 == $val2

13) // for one line comments
/*comment*/ for multi-line comments

14) see http://www.php.net/ for full documentation

Answer 5

Jake answered all correctly but here are alternative ways for writing if statement:

if(condition) echo "worked";

if(condition):
echo "worked";
endif;

Answer 6

Many pool chemicals are used to sanitize, clean, or balance the water in swimming pools, hot tubs, and spas. A partial list of pool chemicals includes chlorinated isocyanurates, lithium hypochlorite, sodium bicarbonate, potassium monopersulfate, hydrogen peroxide, sodium hypochlorite , calcium hypochlorite, and certain ammonium, brominated, copper and silver compounds, and muriatic acid. Pool chemicals involved in fire or toxic vapor releases are likely to include those that add chlorine or a chlorine ion to the pool water for bacterial control. Chemicals that release chlorine are among the group of chemicals classified as "oxidizers." These pool oxidizer chemicals include calcium hypochlorite, sodium hypochlorite, and chlorinated isocyanurates. Other pool chemicals are used to control the growth of algae or fungus, to adjust the acidity or alkalinity (pH control) and to clarify the pool water.

The pH of a pool is controlled by adding either acid or alkali products. An acid, either muriatic acid (also known as hydrochloric acid) or sodium bisulphate, is added to lower the pH. To raise the pH, an alkali, sodium carbonate (also known as soda ash) is added.

Additionally, pools use sanitizing chemicals to remove algae, harmful bacteria, dirt, germs, and organic matter carried into the pool on people’s bodies and by the wind. These chemicals oxidize organic matter. Most typically, a chlorine product is used to sanitize the pool. Either a liquid chlorine (typically sodium hypochlorite) or dry chlorine (usually calcium hypochlorite) is used.

Pool and spa chemicals may be corrosive, meaning they may cause skin and eye damage. Many pool chemicals, including different types of chlorine, can react violently when mixed, producing toxic gases, fire, and/or an explosion.
