PHP reads local file operation function_PHP tutorial

The most commonly used methods for reading local files in php are fopen and fread functions. There are other functions such as php file_get_contents that can read local files or remote files. Let's introduce them one by one below. ​

fopen() function
Open the file directly

Example

The code is as follows

Copy code

代码如下	复制代码
$file = "111.txt"; $fp = fopen($file,"r"); if ($fp){  while(!feof($fp)){   //第二个参数为读取的长度   $data = fread($fp, 1000);  }  fclose($fp); } echo $data; ?>

$file = "111.txt";

$fp = fopen($file,"r");

if ($fp){

while(!feof($fp)){

//The second parameter is the read length

代码如下	复制代码
echo file_get_contents("test.txt"); ?> 输出： This is a test file with test text.

$data = fread($fp, 1000);

}

fclose($fp);

代码如下	复制代码
$dir = opendir('/movie'); while(($file = readdir($dir))!=false){   if ($file!="." && $file!="..") {     $ns = explode('.', $file);     echo $ns[0];   } } closedir($dir); ?>

}
echo $data; ?>

The file_get_contents() function reads the entire file into a string Example

echo file_get_contents("test.txt"); ?> Output: This is a test file with test text.
