How do you store the return value for substr_count in a session?

[sh0wtym3]

I want to be able to do this

$results = substr_count("This is a test sentence","test");

$_SESSION("results") = "$results";

 

 

But when I try to I get the following error

"Fatal error: Can't use function return value in write context"

[premiso]

session_start(); // needs to be before any output

$results = substr_count("This is a test sentence","test");
$_SESSION["results"] = $results;

 

Should work. You were just using ( ) instead of [ ] .
