Then we check whether the file exists.

Use the feof file to check whether the end of the file has been reached, then use the fread loop to read the file content and output the read content.

#After reading is completed, remember to use the fclose method to close the file handle.

The script is finished, let’s run it. Then compare the output content with the content of the file we want to read.

OK, you’re done! The following is the source code:

<?php
// 定义并初始化要访问的文件路径
$filename = &#39;./my.txt&#39;;
// 检查文件是否存在，不存在直接退出
if (!file_exists($filename)) {
echo &#39;file does not exists&#39;;
exit;
}
// 以只读方式打开该文件
$handle = fopen($filename, &#39;r&#39;);
// 使用feof方法判断是否到文件末尾
// 使用fread方法进行内容读入
while (!feof($handle)) {
$line = fread($handle, 1024);
echo $line;
}
// 操作完成后将文件关闭
fclose($handle);
