Strpos() problem

PHP
1

Here’s my code:

$haystack = “,18,19,42,”;
$needle = “,18,”;
if (strpos($haystack,$needle)) {
echo ‘TRUE’;
} else {
echo ‘FALSE’;
}

I expect TRUE , but get FALSE.

What am I missing?

That’s because strpos doesn’t return true. You either get FALSE if the string isn’t found, or you get the position that the value begins with (in your case, you’ll get 0)

When I first started PHP I used to prefix a dummy character to the “haystack” until I understood…
