Cast integer php - remove a character from a string

I have this code, and I'm doing castto delete a character €.

    $t = "€2000";
    $venc = (int)$t;
    echo $venc; // actually echo is 0 and i want 2000 (remove symbol)

Conclusion 0, not 2000, so the code does not work as I expect.

What is the reason (int)$t;not echo 2000?

thank

the casting procedure does not delete invalid characters, but starts from the beginning and stops when the first invalid character is reached, and then converts it to a number, in your case, the Euro character is invalid and is the first character, the result of which is 0.

check out http://www.php.net/manual/en/language.types.string.php#language.types.string.conversion

you can try (int)preg_replace('/\D/ui','',$t);

, , , ,

(float)preg_replace('/[^0-9\.]/ui','',$t);

+8

$t = preg_replace('/[^0-9]/i', '','€2000');
$venc = (int)$t;
echo $venc;
+4

substr

   echo substr($t,3);  // returns "2000"
0
$t = "€2000";
$venc = (int)substr($t,1);
echo $venc;
0
