Variables

[CyberDog]

Hello,

I asked this question before (sorry) but I forgot/ran into some problems.

There are more ways to defina an variable:

1. $var = 'value'; Notice the '
2. $var = "value"; Notice the "

and what is the third? Something like /"value/" I think...
Thank you.

As far as I know there're only two ways to define a variable: the =
operator and functions that receive arguments by reference and modify
arguments:

$var='value';

and

function asign_value(&$f oo){
$foo='value';
}
asign_value($va r);

If you mean constants, you use the define() function:

define('FOO', 'value');
echo FOO;

And if you're talking about strings, you need to consider single quotes,
double quotes and dot (concatenation operator). Double quotes make PHP
perform variable parsing in strings.

Thank you, I learnedquite a fiew things now, but not what I was trying
to learn...

To elaborate my question a little further:

I have an variable that echoes to the screen at the end of the page.
I have some dynamicly assigned simple HTML code procesed in the script.
That simple HTML contains a java script and some links... but java
script piece of code containd both " and ' within.

How do I put data that contains both ' and " into a variable $var?

It's all in the fine manual, so please read the thing:

That's the purpose of mirrors: if one is down, you switch to another one.

Thank you, I will find much use for it in the future, in the meantime I
used $var= 'bla "bla" /'bla/' ' ect.

Try going to main page and then clicking on "Mirror sites" on bottom bar. I
only get redirected to mirrors when I perform searches.

You can also do:

$var = 'bla "bla" '. "'bla'";

I have a strong dislike for escaping quotes since it makes the lines so
hard to read.
