php读取文件内容的三种方法:

//**************第一种读取方式*****************************
复制代码 代码如下:
header("content-type:text/html;charset=utf-8");
//文件路径
$file_path="text.txt";
//判断是否有这个文件
if(file_exists($file_path)){
if($fp=fopen($file_path,"a+")){
//读取文件
$conn=fread($fp,filesize($file_path));
//替换字符串
$conn=str_replace("\r\n","
",$conn);
echo $conn."
";
}else{
echo "文件打不开";
}
}else{
echo "没有这个文件";
}
fclose($fp);

//*******************第二种读取方式***************************
复制代码 代码如下:
header("content-type:text/html;charset=utf-8");
//文件路径
$file_path="text.txt";
$conn=file_get_contents($file_path);
$conn=str_replace("\r\n","
",file_get_contents($file_path));
echo $conn;
fclose($fp);

//******************第三种读取方式,循环读取*****************
复制代码 代码如下:
header("content-type:text/html;charset=utf-8");
//文件路径
$file_path="text.txt";
//判断文件是否存在
if(file_exists($file_path)){
//判断文件是否能打开
if($fp=fopen($file_path,"a+")){
$buffer=1024;
//边读边判断是否到了文件末尾
$str="";
while(!feof($fp)){
$str.=fread($fp,$buffer);
}
}else{
echo "文件不能打开";
}
}else{
echo "没有这个文件";
}
//替换字符
$str=str_replace("\r\n","
",$str);
echo $str;
fclose($fp);
读取INI配置文件的函数:
$arr=parse_ini_file("config.ini");
//返回的是数组
echo $arr['host']."
";
echo $arr['username']."
";
echo $arr['password']."
";
