Re: Problems converting strings with 0 to integer

Hi, The core of the code is simply $fp = fopen('file.tab', 'rb'); while(!feof($fp)) { $line = fgets($fp); $data = explode("\t", $line); ... } So I try to manipulate the $data[X]. For example $data[0] is supposed to be numeric so I $n = (int) $data[0] One other thing if the second column should contain a string. If I check the string visually it is correct but a if( $data[1] == 'stringX') is false even if in the file I can see this (and print those two) I even did a md5 of both and they are different. I seems to be an encoding issue. Is it safe to use explode with utf8 strings? I even tried this code but no match found (jst to replace the explode) $str = "abc 文字化け efg"; $results = array(); preg_match_all("/\t/u", $str, $results); var_dump($results[0]); (I am sending this again without the reply because the first email was refused for some reason)
