本文实例讲述了PHP简单实现文本计数器的方法。分享给大家供大家参考,具体如下:
<?php if (file_exists('count_file.txt')) { $fil = fopen('count_file.txt', r); $dat = fread($fil, filesize('count_file.txt')); echo $dat+1; fclose($fil); $fil = fopen('count_file.txt', w); fwrite($fil, $dat+1); } else { $fil = fopen('count_file.txt', w); fwrite($fil, 1); echo '1'; fclose($fil); } ?>
希望本文所述对大家PHP程序设计有所帮助。
