PHP获取文件行数的方法,
本文实例讲述了PHP获取文件行数的方法。分享给大家供大家参考。具体分析如下:
提供两种实现方法,虽然第二种简单易懂,但是第一种效率最好
第一种:
<?php $file_path = 'xxx.txt'; //文件路径 $line = 0 ; //初始化行数 //打开文件 $fp = fopen($file_path , 'r') or die("open file failure!"); if($fp){ //获取文件的一行内容,注意:需要php5才支持该函数; while(stream_get_line($fp,8192,"\n")){ $line++; } fclose($fp);//关闭文件 } //输出行数; echo $line; ?>
第二种:
<?php $line = count(file('filename')); echo $line; ?>
第二种方式因为要保存文件的内容,效率上会很差
希望本文所述对大家的php程序设计有所帮助。
