echo '<a href="$var1">$var2</a>'; why won't this work?

[Aro2220]

Hi, I am trying to get the following script to run but it doesn't put the values of the variables into the echo...

 

echo '<a href="$var1">$var2</a>';

 

result is an html link called $var2 that links to $var1

 

if i echo "$var1";

or

echo "$var2";

i get the value of the variable displaying correctly.

 

Why is this happening?

How do I do what I want to do?

[Aro2220]

never mind, i figured it out.

 

echo "<a href='$var1'>$var2</a>";

works as I intended it to.

 

I'm still not entirely sure about when ' and " should be used, but oh well!

 

Thanks

Single quotes do not parse variables, they are used when the output doesn't need to contain php variables.  Double quotes do parse php variables.  Another alternative is heredoc.

Single quotes are simple strings, and will to be parsed by PHP. Double quotes will be parsed.

 

$var = 'no vars here';

echo 'The var is $var';   // Will output: The var is $var
echo "The var is $var";  // Will output: The var is no vars here
