正常情况下,我们可以使用fseek来读取,好处就是不会一次性读取,以下代码只适合边取边处理的情况,不适合一次性读取一次性处理。
可以用以下办法生成测试文件
$file_handle = fopen("./csdn.txt", "rb+");
for ($index1 = 1; $index1 fwrite($file_handle, 'http://jb51.net'.$index1."\r");
}
fclose($file_handle);
读取处理代码如下:
$i = 0;
$now = '';
while ($i >= 0) {
if ($i>10) {
break;
}
fseek($file_handle, 0, SEEK_CUR);
$now = fgetc($file_handle);//可以自己写个判断false表示文件到头
if ($now == "\r") {
echo '找到断点';
}
echo $now;
$i++;
}
fclose($file_handle);
