Introduction: Learn the Basics of Php (works)
in this instructable ill show you how to:
setup a local web server
code some php
Step 1: You Will Need
Step 2: Xampp
(if you want me to post one in text just comment bellow)
Step 3: Echo and Print
all the php you write will be inbetween this
lets start by saying something to do this we use echo.
ok here we go
echo "this is text";
so whats this mean? ill do a brack down
tells the computer to say something
tells the computer the string has started
tells the computer the string has ended.
Step 4: Variabels
what are variabals?
there like cut and past but in php
so whats the point of that
say there was some song string that you used alot like
this is a looooooooooooooooooooooooooooooooong string.
and you dont want to type that every time you want to say it then you would use a variabal. but how? with ease. here:
$long = "this is a looooooooooooooooooooooooooooooooong string.";
you can also put strings together with a
$str1 = "this is my first string. this is my";
$str2 = "second string.";
echo " $str1.$str2";
put what if i want to say something with $ or "" in it?
use a \.
echo "Liam said \"the his name is Liam too \"
echo "we will have to charge him \$10";
Step 5: Php Can Do Math
php can do math!
just follow along!
say i wanted to add 5 and 5 together then i go
this will output
so now lets to some more advanced math
here is a key
add = +
take away = -
divide = /
multiply = *
