stupid simple question

how can i output an image in this code;

PHP Code:


		
			
$config["M_Paintball_100"]="

<h1>Times:</h1> 9.45am – 2pm or 11.30am – 3.30pm on a half day, full day 9.45am – 3.30pm.

";

can you explain what the difference is between the single and double qoutes, sorry for being simple, justtrying to understand everything.

Double quotes can be used like this;

PHP Code:


		
			
echo "Hello, my name is $name.";

This most likely, when defined $name, exports Hello, my name is insert_name_here

The same doesn't go for the single quotes although they are a lot easier to use. Since you'll make echo's like this;

PHP Code:


		
			
echo '<a href="link.htm">link</a>';
// and of course
$query = mysql_query('SELECT * FROM table WHERE name = "'.$name.'"');

Adam would be more qualified to explain it into more depth but those are the basics really. Also, double quotes understand the usages of "\n" (HTML Enter) and "\r" (HTML Tab).

Good luck!

... that's correct ReSpawN, but I think the real issue was non-escaped double quotes. That's the reason Wildhoney corrected the string.

In any event, bmathers, you should spend some time reading through the PHP Manual, especially the language reference.

Just to expand on Sock's explanation a tiny bmathers, using quotes inside quotes (as with your example), you're causing confusion to the interpreter, it doesn't know when the sentence is ending and when it's beginning.

That means it's taking '../images/stag.gif' and trying to parse/ call it rather than outputting it, as you're intending.

Couple of bits re. ReSpawn's points,

1. If you use a variable in a string, enclose it in curly braces:

PHP Code:


		
			
// not strictly necessary but easier to spot
echo "Hello, my name is {$name}.";

2. There's a slight performance benefit from using apostrophe's over quotes when dealing with strings. Apostrophe's are taken as literals so it doesn't try to parse data as strings in quotes' do.

I also published a little article on double and single quotes over here.
