PHP class used to parse. htpasswd files

Sometimes you need to obtain the content of the. htpasswd file, you can use the following code class. if you need it, you can refer to the. htpasswd File example:
User1: {SHA} kGPaD671VNU0OU5lqLiN/h6Q6ac =
User2: {SHA} npMqPEX3kPQTo + x/+ ZckHDrIcQI =
User3: {SHA} q1Fh2LTUjjkncp11m0M9WUH5Zrw =
Copy codeThe code is as follows:
Class Htpasswd {
Private $ file = '';
Private $ salt = 'aynlj2h. 74VEfI ^ BZElc-Vb6G0ezE9a55-Wj ';
Private function write ($ pairs = array ()){
$ Str = '';
Foreach ($ pairs as $ username => $ password ){
$ Str. = "$ username: {SHA} $ password \ n ";
}
File_put_contents ($ this-> file, $ str );
}
Private function read (){
$ Pairs = array ();
$ Fh = fopen ($ this-> file, 'r ');
While (! Feof ($ fh )){
$ Pair_str = str_replace ("\ n", '', fgets ($ fh ));
$ Pair_array = explode (': {SHA}', $ pair_str );
If (count ($ pair_array) = 2 ){
$ Pairs [$ pair_array [0] = $ pair_array [1];
}
}
Return $ pairs;
}
Private function getHash ($ clear_password = ''){
If (! Empty ($ clear_password )){
Return base64_encode (sha1 ($ clear_password, true ));
} Else {
Return false;
}
}
Public function _ construct ($ file ){
If (file_exists ($ file )){
$ This-> file = $ file;
} Else {
Die ($ file. "doesn't exist .");
Return false;
}
}
Public function addUser ($ username = '', $ clear_password = ''){
If (! Empty ($ username )&&! Empty ($ clear_password )){
$ All = $ this-> read ();
If (! Array_key_exists ($ username, $ all )){
$ All [$ username] = $ this-> getHash ($ clear_password );
$ This-> write ($ all );
}
} Else {
Return false;
}
}
Public function deleteUser ($ username = ''){
$ All = $ this-> read ();
If (array_key_exists ($ username, $ all )){
Unset ($ all [$ username]);
$ This-> write ($ all );
} Else {
Return false;
}
}
Public function doesUserExist ($ username = ''){
$ All = $ this-> read ();
If (array_key_exists ($ username, $ all )){
Return true;
} Else {
Return false;
}
}
Public function getClearPassword ($ username ){
Return strtolower (substr (sha1 ($ username. $ this-> salt), 4, 12 ));
}
}

Usage
Copy codeThe code is as follows:
$ PasswdHandler = new Htpasswd ('/home/myuser/. htpasswd ');
// Add a user with name 'user1' and password 'I prefer to use passphrase rather than password.' if it doesn' t exist in. htpasswd.
$ PasswdHandler-> addUser ('user1', 'I prefer to use passphrase rather than password .');
// Delete the user 'user1' if it exists in. htpasswd.
$ PasswdHandler-> deleteUser ('user1 ');
// Check if user 'user1' exists in. htpasswd.
If ($ passwdHandler-> doesUserExist ('user1 ')){
// User 'user1' exists.
}
