Question

I am needing to create a foreach statement that will run through and create conditions for a conditional statement. I wrote this bit of code, not expecting it to work, and of course it didn’t…

$filename = "whitelist.txt";
$handle = fopen($filename, 'r');
$whitelist = fread($handle, filesize($filename));
fclose($handle);
$whitelist = explode("\n", $whitelist);
if (
  foreach ($whitelist as $value) {
    strpos($ref, 'http://'.$value.'/')===0 ||
  }
)

So, should this ever be able to work? Or am I just crazy? If there is really no way to put a loop in the condition like this, could someone suggest a better way to do this? Much appreciated!

Answer 1

Compute the value beforehand, you cannot use a loop as an expression:

$val = false;

foreach ($whitelist) {
   $val = $val || strpos($ref, 'http://'.$whitelist.'/')===0;
}

if($val) {
    // ...
}
