在php中将字符串转换为整数时返回零

Question

when I want to convert a numeric string variable into integer in php, the return value is zero. I used all ways to convert it! such as:(int), (integer), intval(), settype(), eval(), etc. all of them return zero!

var_dump($myVariable) prints the following:

string(4) "۲۹"

Answer 1

I found it! before converting string to integer, I should convert arabic number to english using this function:

function convert($string) {
$persian = array('۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹');
$num = range(0, 9);
return str_replace($persian, $num, $string);
}

now, I can convert it! thanks from kingkero.
