Answer 1

您可以使用fgets（）函数逐行读取文件：

didFinishLaunching

Answer 2

只需在循环中放置一个增量计数器，只有当该计数器与您需要的行号匹配时才会回显，然后您可以简单地摆脱循环

$required = 5;

$line = 1;
$fp=fopen("test.txt",r)or exit("khong tim thay file can mo");
while(!feof($fp)){
    if ($line == $required) {
        echo fgets($fp);
        break;
    }
    ++$line;
}
fclose($fp);

Answer 3

$myFile = "text.txt";
$lines = file($myFile);//file in to an array
echo $lines[1]; //line 2
