PhP file read error

[mider]

Hi!  So to put this very simply, i made a program that can access different streaming services for my home theater setup.  I am making a web control for it and I'm having trouble with PhP.  I want it to detect if a file contains (or equals) "netflix" and for it to spit out in html: Currently Watching: Netflix

here is my current code:

 

 

<?php
$currentStream = fopen("control/current.txt", "r") or die("Unable to open file!");
if (fread($currentStream,filesize("control/current.txt")) = netflix) ?>
  <h2>Currently Watching: Netflix</h2>
<?php
endif
?>

 

 

 

 

The error I am getting says:

 Fatal error: Can't use function return value in write context in C:\wamp\www\structure.php on line 41

Line 41 is the line the one that says:

 

if (fread($currentStream,filesize("control/current.txt")) = netflix) ?>

You are only using a single equals sign, this means you are trying to set 

fread($currentStream,filesize("control/current.txt"))

to be netflix which obviously you cannot do.

 

In an IF statement you can either use two or three equals signs.

Two will compare ignoring the case so an integer could equal a string like 2 == '2'.

Three will only be true if the type and value match so 2 === 2 is true, 2 === '2' is false and '2' === '2' would be true.

 

Then your string needs to be wrapped in quotes or it won't work.

 

So in your case it should be:

 

if (fread($currentStream,filesize("control/current.txt")) === "netflix") ?>

THANK YOU SO MUCH!! Lol I could not figure out what i was doing wrong.  I wanted to post this on StackExchange but I have only ever posted a couple questions and i've been banned.  Probably cause i haven't used it in like a year
