Hi all

I am a newbie to learning php but will complete it soon:biggrin:
I am learning from SAMS TEACH YOURSELF PHP IN 10 MINUTES + Programmers Introduction to php4.

I hope you will help me all:lockd:

Thanks in advance

So here is my first php script.Please point out the mistakes if any

<html>
<body>
<?php
echo today date is ('j H Y');
echo and time is;
echo ('H:i:s');
?>
</body>
</html>


Can anyone tell me the difference between single quoted(' ') and double quoted strings (" ").Please help me.

The code must be
Code: 
<html>
<body>
<?php
echo "today date is " . date('j H Y');
echo "and time is";
echo date('H:i:s');
?>
</body>
</html>

I think... Single quotes and double quotes are just same. But, they can't be mixed.

Better you start learning PHP5, since 4 is already out dated and soon they will release PHP6.

Btw, dunno where i read that but, i think double quotes are more strict... o_O~ Well, i always use double quotes ... just single when is to parse something, like $_GET['blablabla']

You must use single ' if the sentence contains a " and " if it contains ' if you don't escape them. I suggest escaping such things. Otherwise I don't think there is any differens

For your example, there's no significant difference, but when you're working with variables in php there is.

PHP evaluates variables enclosed in double quotes:

<?php
$thing="this car";

echo "I need to buy $thing.";
?>
Displays: I need to buy this car.

When you use single quotes, the variable isn't evaluated:
<?php
$thing="this car";

echo 'I need to buy $thing.';
?>
Displays: I need to buy $thing.

Cheers and good luck with your work.

double quates are literal.. for example..


echo date('H:i:s'); WILL DISPLAY DATE IN THAT FORMAT

echo date("H:i:s"); WILL LITERALLY DISPLAY "H:i:s"

PHP 5.3 is coming before PHP 6, 5.3 will introduce new features coming in PHP6. You might want to wait a bit before learning;).

also, when having a variable = another variable, you dont need quotes as long as its that variable itself or +, -, *, or / by a number

Why? the fundamentals are the same across all versions of PHP.
