PHP Tutorials – Putting Text into Variables

 

 

In the previous section, you saw how
to put numbers into variables. But you can also put text into your variables.
Suppose you want to know something about the coats you own. Are they Winter
coats? Jackets? Summer coats? You decide to catalogue this, as well. You can
put direct text into your variables. You do it in a similar way to storing numbers:

$coats1 = “Winter Coats”;

Again, our variable name starts with a dollar sign ($). We’ve then given it
the name coats1. The equals sign follows the variable name. After the equals
sign, however, we have direct text – Winter Coats. But notice the double quotation
marks around our text. If you don’t surround your direct text with quotation
marks, then you’ll get errors. You can, however, use single quotes instead of
double quotes. So you can do this:

$coats1 = ‘Winter Coats’;

But you can’t do this:

$coats1 = ‘Winter Coats”;

In the above line, we’ve started with a single quote and ended with a double
quote. This will get you an error.

We can store other text in the same way:

$coats2 = “Jackets”;
$coats3 = “Summer Coats”;

The direct text will then get stored in the variable to the left of the equals
sign.

So, to recap, variables are storage areas. You use these storage areas to manipulate
things like text and numbers. You’ll be using variables a lot, and on the next
few pages you’ll see how they work in practice.
