PHP Learning notes PHP file operation,

Fstat function: Displays all the information of a file

$file _path = "test.php", if ($fp =fopen ($file _path, "A +") {  $file _info=fstat ($fp);  echo "
";  Print_r ($file _info);  echo "
";  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", "
", $con); echo" File content is ". $con;//The second: Read all the files $con = file_get_contents ($file _path); $con = Str_replace (" \ r \ n ","
", $con); echo" File content is ". $con;//The third type: Read $buffer = 1024; In order to download the security, it is best to use the file byte read counter $file_count = 0;//feof used to determine whether the file is read to the end of the document while (!feof ($fp) && ($file _size-$file _count> 0) {$file _data = fread ($fp, $buffer);//Statistics read the number of bytes $file_count+ $buffer; echo $file _data;  

Third, write the file:

1, the traditional method writes the file  $file _path = "test.txt";  if (file_exists ($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";  $con = "Hi Beijing!" \ r \ n ";  File_put_contents ($file _path, $con, file_append);  

　　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);      

　V. Copy files:

if (!copy ("E:\\test.txt", "D:\\1.txt")) {  echo "fail";} else{  

　Vi. Creating files

To create a folder:

$path = "E:\\happy"; Folder path $path = "E:\\HAPPY\AAA\BBB"; Multilevel folder if (!is_dir ($path)) {  if (mkdir ($path, 0777,true)) {    echo "success";  } else{    echo "fail";  }} else{  

To create a file:

Vii. Deletion of files:

　　To delete a folder:

$path = "E:\\HAPPY\AAA\BBB"; Multilevel folder if (RmDir ($path)) {  

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";}

The above is a small part of the PHP file to introduce the operation of the relevant knowledge, I hope to be helpful to all of you.
