parsing question (error)

[LC8Joe]

I'm trying parse this line:

 

echo '<a href="'.$_SERVER['PHP_SELF'].'?function='$i'">Click here to call a function</a>';

 

and keep getting an error, how can I place the value of i$ ?

 

Can you please help me?

Variables do not get parsed inside single quoted strings. Either use double quotes and escape your existing double quotes, or use concatenation.

Hi Jessica, thank you very much for your answer but it seams that I just don't get it

 

I'm trying to get the value of $i when I click the link but even when I don't get a parse error, it will call function= with no value returned

 

$i = 55;

echo '<a href=\"'.$_SERVER['PHP_SELF'].'?function="$i"'.">Click here to call the function</a>";

if(isset($_GET['function']))
{
    echo $_GET['function'];
}

Try this:

 

echo '<a href="' . $_SERVER['PHP_SELF'] . '?function=' . $i . '">Click here to call the function</a>';

 

What Jessica meant was you could do this:

 

echo "<a href=\"{$_SERVER['PHP_SELF']}?function={$i}\">Click here to call the function</a>";

 

Double quotes will allow you to place variables in he string. However, the first method is quicker to parse
