文件操作 php里的一些文件操作函数使用演示

function fileToArray($file) {
    if (!$array = file($file)) {
        die("fileToArray: Could not read file!");
    }
    return $array;
}

function fileToString($file) {
    if (!$string = file_get_contents($file)) {
        die("fileToString: Could not read file!");
    }
    return $string;
}

function stringToFile($file, $string) {
    if (!$handle = fopen($file,"w")) {
        die("stringToFile: Could not open file");
    }
    if (!fwrite($handle, $string))
        die("stringToFile: Could not write file");
    }
    fclose($handle); // Should the close handle be error checked, or would I be over doing it?
}

function arrayToFile($file, $array) {
    if (!$handle = fopen($file,"w")) {
        die("arrayToFile: Could not open file");
    }
    for ($i = 0; $i < count($array); $i++) {
        if ($i == count($array) - 1) {
            if (!fputs($handle, $array[$i])) {
                die("arrayToFile: Could not write file");
            }
        } else {
            if (!fputs($handle, $array[$i]."\n")) {
                die("arrayToFile: Could not write file");
            }
        }
    }
    fclose($handle);
}
