php - Can't get the double quotes right -

i have following works fine:

header("location: /index.php", true, 300); 

but want filename dynamic, i.e.

header("location: /" . $_session['initiating_url']); 

this works fine, however, still need , true, 300 @ end, can't seem figure out:

header("location: /" . $_session['initiating_url'] . "\"", true, 300); header("location: /" . $_session['initiating_url'] . """, true, 300); 

but don't seem work correctly. bottom 1 gives me syntax error in editor. , second last example doesn't redirect @ all.

you don't need add explicit closing " when concatenating strings:

header("location: /" . $_session['initiating_url'], true, 300); 

for clarity:

$path = 'home'; echo "location: /" . $path;          // location: /home echo "location: /home";              // location: /home echo "location: /" . $path . "\"";   // location: /home" echo "\"location: /" . $path . "\""; // "location: /home"
