How to create a logfile in php

To write to a log file and make a new one each day, you could use date("j.n.Y") as part of the filename.

//Something to write to txt log
$log  = "User: ".$_SERVER['REMOTE_ADDR'].' - '.date("F j, Y, g:i a").PHP_EOL.
        "Attempt: ".($result[0]['success']=='1'?'Success':'Failed').PHP_EOL.
        "User: ".$username.PHP_EOL.
        "-------------------------".PHP_EOL;
//Save string to log, use FILE_APPEND to append.
file_put_contents('./log_'.date("j.n.Y").'.log', $log, FILE_APPEND);

So you would place that within your hasAccess() method.

public function hasAccess($username,$password){
    $form = array();
    $form['username'] = $username;
    $form['password'] = $password;

    $securityDAO = $this->getDAO('SecurityDAO');
    $result = $securityDAO->hasAccess($form);

    //Write action to txt log
    $log  = "User: ".$_SERVER['REMOTE_ADDR'].' - '.date("F j, Y, g:i a").PHP_EOL.
            "Attempt: ".($result[0]['success']=='1'?'Success':'Failed').PHP_EOL.
            "User: ".$username.PHP_EOL.
            "-------------------------".PHP_EOL;
    //-
    file_put_contents('./log_'.date("j.n.Y").'.txt', $log, FILE_APPEND);

    if($result[0]['success']=='1'){
        $this->Session->add('user_id', $result[0]['id']);
        //$this->Session->add('username', $result[0]['username']);
        //$this->Session->add('roleid', $result[0]['roleid']);
        return $this->status(0,true,'auth.success',$result);
    }else{
        return $this->status(0,false,'auth.failed',$result);
    }
}

Create a log file in PHP

For what it's worth MySQL provides the very efficient ARCHIVE storage engine, suitable for write-a-lot read-infrequently use patterns.

It's a good choice if you want your log data in the DBMS (backed up, etc).

It's also a good choice for log data when your web app runs on multiple servers: all the entries go to one place, and you don't have to wonder which machine a particular log entry lives on.

Using php to write to a log file

Why not just use error_log()? With the message_type set to 3 (second parameter) the message will be written the the file specified in the third parameter:

$message = $_GET['w'];
$logfile = 'logfile.log';

// Debug: A line for verifying I have the message
echo "Writing message '$message' to logfile<br>";

error_log($message."\n", 3, $logfile);

// Debug: read back the log file to verify thatthe line has been written
readfile($logfile);

Note the newline appended to the message as error_log() doesn't do this for you.

Note also that permissions must be set to allow the web server to write to the target file. This is true whether using error_log() or file_put_contents()

How to create a log file in PHP

error_log("You messed up!".$my_message, 3, "/var/tmp/custom-errors.log");

Create or write/append in text file

Try something like this:

 $txt = "user id date";
 $myfile = file_put_contents('logs.txt', $txt.PHP_EOL , FILE_APPEND | LOCK_EX);

Creating A log File every day By php and Javascript

Crate one more variable like the $date one:

$newTime = date('dmY');

And then add this in your file name:

$file = "/home/shakilofficial/public_html/vtinfo/mainindex{$newTime}.html";

So you will have a different file every day with different name

I believe you should have an automatic generated error log which is stored in your root folder.

Check for a file called "php_errorlog" or something similar to this.

You can then download it and open it with Notepad or any other editor.

Php code to Generate Log File

<?php
    $filename = "logs.php";
    $lines = file($filename);
    if(count($lines)!=0){
        $data  = explode( " :- ", $lines[count($lines) -1 ]);
        if(date('d-M-y')   ==  $data[0]){
            $data[1]++;
            $lines[count($lines) -1 ] = $data[0].' :- '. $data[1];
        }else{
            $lines[] = date('d-M-y').' :- 1';
        }

    }else{
        echo 'Empty';
        $lines[] = date('d-M-y').' :- 1';
    }
    file_put_contents($filename, implode("\n", $lines ) );

?>
