I am trying to create a function which will generate lines using yield. But I got this error:

Parse error: syntax error, unexpected '$line' (T_VARIABLE)

$emails = file_get_contents("addresses.txt");
function yieldEmails($emails){
 $start_time = microtime(true);
 foreach ($emails as $i => $em):
   $line = array( "test@test.com", 12);
   yield $line;
 endforeach;
}

$indexes = yieldEmails($emails);

Can you explain what's wrong?

Is the variable `$offset` defined ? – sh1hab Oct 20 '19 at 09:30
what do the other functions do there? – Professor Abronsius Oct 20 '19 at 09:34
OK, I have simplified the code inside the loop. – Johny Bony Oct 20 '19 at 09:37
@JohnyBony There is no parse error with this code anymore. What exactly is the error message you get now and what is the current source code you have? And if relevant, add the PHP version you are using. – Progman Oct 20 '19 at 09:41
@Progman: Just change `$line = array( "test@test.com", 12);` and I got the parse error still. PHP 5.4 – Johny Bony Oct 20 '19 at 09:44
@JohnyBony "yield" was introduces in version 5.5, see https://www.php.net/manual/en/language.generators.overview.php – Progman Oct 20 '19 at 09:45
Ah, I see now. Thanks – Johny Bony Oct 20 '19 at 09:47
If you are still using PHP 5 I strongly recommend to upgrade as soon as possible. This version is no longer supported. [Let Rasmus Lerdorf explain it to you](https://youtu.be/wCZ5TJCBWMg?t=2434) – Dharman Oct 20 '19 at 11:26
@Dharman: Not possible. I am using Windows XP and not gonna change. – Johny Bony Oct 20 '19 at 12:52
