分享下php读取文件内容的三种方法。
php读取文件内容:
- header("content-type:text/html;charset=utf-8");
- $file_path="text.txt";
- if(file_exists($file_path)){
- if($fp=fopen($file_path,"a+")){
- $conn=fread($fp,filesize($file_path));
- $conn=str_replace("rn","<br/>",$conn);
- echo $conn."<br/>";
- }else{
- echo "文件打不开";
- }
- }else{
- echo "没有这个文件";
- }
- fclose($fp);
-
-
- header("content-type:text/html;charset=utf-8");
- $file_path="text.txt";
- $conn=file_get_contents($file_path);
- $conn=str_replace("rn","<br/>",file_get_contents($file_path));
- echo $conn;
- fclose($fp);
-
-
- header("content-type:text/html;charset=utf-8");
- $file_path="text.txt";
- if(file_exists($file_path)){
- if($fp=fopen($file_path,"a+")){
- $buffer=1024;
- $str="";
- while(!feof($fp)){
- $str.=fread($fp,$buffer);
- }
- }else{
- echo "文件不能打开";
- }
- }else{
- echo "没有这个文件";
- }
- $str=str_replace("rn","<br>",$str);
- echo $str;
- fclose($fp);
- 读取INI配置文件的函数:
- $arr=parse_ini_file("config.ini");
- echo $arr['host']."<br/>";
- echo $arr['username']."<br/>";
- echo $arr['password']."<br/>";
