PHP string to integer not playing nice, encoding issue?

Question

I am reading in a CSV file (in UTF-8 encoding). One of the values is a number and when I try to cast it as an integer so I can do some calculations it is just being set to zero. What am I doing wrong?

var_dump ( $row3[_MM_Impressions] );
//writes: string(5) "59"

$imps = (int)$row3[_MM_Impressions];
var_dump($imps);
//writes: int(0) 

$imps = $row3[_MM_Impressions]*1;
var_dump($imps);
//writes: int(0) 

$imps = intval($row3[_MM_Impressions]);
var_dump($imps);
//writes: int(0)

Try removing the null bytes preg_replace("/\x00/", "" , $row3[_MM_Impressions]) — Musa

You have HEX string number in your vars... so why don't you use hexdec?

Returns the decimal equivalent of the hexadecimal number represented by the hex_string argument. hexdec() converts a hexadecimal string to a decimal number.

hexdec() will ignore any non-hexadecimal characters it encounters.

Unfortunately it gets the wrong int number though. Vardump (original): string(5) "59" Vardump (after hexdec ($row3[_MM_Impressions])): int(89) int(89) here is another example that should be 49 as an int: string(5) "49" int(73) int(73)
