PHP Paxton's Web Development School Part: 2

[EvulMastah]

Simple question:

$x++;

Can it be wrotten as:

$x = $x + 1;

If no how I can add ex. 2 to $x in every loop?

$x += 2;

Calculator

   <?php
function calculator1 ($num1,$num2)
{
return $num1+$num2;
}
echo calculator1 (1,5);
function calculator2 ($num3,$num4)
{
return $num3/$num4;
}
echo calculator2 (1,5);
function calculator3 ($num5,$num6)
{
return $num5*$num6;
}
echo calculator3 (1,5);

?>

LOOP!

  <?

for($x = 0; $x<100; $x++) {
if($x%2)
echo $x."<br/>";
if($name == "math1")
break;
}

echo $name;

?>

Waiting for a 3rd one!


Cheers~

That's not exactly "table", but in PHP its called "array". Also it would be good if you would declare the variable as an array:

$var = array();

before writing it elements.

Whats the disadvantage from Lua tables (as many people may be confused)?
In lua tables you may declare constants (ex. 1), key (ex. 2) and autokey (ex. 3)

local table = {bla = "lol"}
table.bla

local table = {"bla" = "lol"}
table["lol"]

local table = {"lol"}
table[1]

while in php you may use only key and autokey

$var = array("lol" => "lol");
$var['lol']

$var = array("lol");
$var[0]

also, Lua tables start with value 1, while php (whats actually standard...) with 0.

ejj bad techer want ban???? am wrajt local table = {"asd" = "lol"} ES WRONG mast wrajt local table = {["asd"] = "lol"}

1.

<?

for($x = 1; $x<=100; $x++) {
if(($x+1)%2 != 0)
continue;

echo $x." ";
}

?>

2.

   <?
function calculator($num1, $num2, $type)
{if($type == "sum") 
{
return $num1+$num2;

}
else if($type == "div")
{
return $num1/$num2;
}
else
return "Select a valid type (sum ,div)";
}
calculator($num1, $num2, $type);
echo calculator(7, 8 , "sulm");
?>

the first homework:

<?
for($x=1, $x<=100, $x++)
echo "the last number is ".$x."<br>";

?>

Second:

<?
function calculator($num1, $num2, add) 
{
   if ($num1 == 0) {
   echo "You cant use 0";}
   elseif ($num2 == 0) {
   echo "you cant use 0";}

Param 'add' is not defined as variable, $ missing.
You can use if ($num1 == 0 || $num2 == 0).

This is phlua jaja
you code as if you were doing a lua script

but i think this will be useful to lots of ppl..
because we are in an Open Tibia community not in a php contest
