PHP file Operations

　Fstat function: Displays all the information of a file

$file _path= "test.php";if($fp=fopen($file _path, "A +")){    $file _info=Fstat($fp); Echo"<pre>"; Print_r($file _info); Echo"</pre>"; Echo"File size is".$file _info[' Size ']; Echo"File last access Time".Date("Y-m-d h:i:s",$file _info[' Mtime ']);}fclose($fp);//be sure to close 

　　Second, file read:

//The first type:$con=fread($fp,filesize($file _path));$con=Str_replace("\ r \ n", "<br>",$con);Echo"File content is".$con;//the second type: Read all the files$con=file_get_contents($file _path);$con=Str_replace("\ r \ n", "<br>",$con);Echo"File content is".$con;//Third: A period of reading$buffer= 1024; //for the security of the download, it is best to read the counter using File bytes$file _count= 0;//feof used to determine whether a file is read to the end of a document while(!feof($fp) && ($file _size-$file _count>0)){$file _data=fread($fp,$buffer);//How many bytes did the statistic read ?$file _count+$buffer;Echo $file _data; }

　　Third, write the file:

   //1. Traditional methods to write files    $file _path= "Test.txt"; if(file_exists($file _path)){        $fp=fopen($file _path, "A +"); //Open Mode: A + is an additional content. The w+ is covered by the original.         $con= "hello!\r\n"; fwrite($fp,$con); Echo"Added successfully! "; }Else{        Echo"File does not exist"; }    fclose($fp); //2, the second method of writing to the file    $file _path= "Test.txt"; $con= "Hello Beijing!" \ r \ n "; file_put_contents($file _path,$con,file_append); Echo"Success";

　　Iv. Application of file operation:

// you can manipulate the INI file. Write the server's configuration in the INI file, and then manipulate it.     DBC.  INI    host=192.168.0.1    Admin=admin    password=123456    demo.  PHP    <? PHP         $con Parse_ini_file ("Dbc.ini");         Print_r ($con);            ? >    // The data in the INI file is read as an array and can be manipulated. 

　　V. Copy files:

if (! Copy ("E:\\test.txt", "D:\\1.txt")) {    echo "fail";} Else {    echo "Success";}

　　Vi. Creating files

To create a folder:

//$path = "E:\\happy"; Folder path$path= "E:\\HAPPY\AAA\BBB";//Multilevel Foldersif(!Is_dir($path)){    if(mkdir($path, 0777,true)){        Echo"Success"; }Else{        Echo"Fail"; }}Else{    Echo"Folder already exists";}

　　To create a file:

$file _path = "E:\\happy.txt"; $fp fopen ($file _path, "w+"); fwrite ($fp, "Hello"); fclose ($fp);

Vii. Deletion of files:

To delete a folder:

$path // Multilevel Folders if (rmdir($path)) {    echo "Success";} // rmdir can only delete empty folders, files or directories under the folder cannot be deleted. 

To delete a file:

$file _path = "E:\\happy.txt"; if (is_file($file _path)) {    if(unlink($file _path)){         Echo "Success";    } Else {        echo "fail";    }} Else {    echo "file does not exist";}
