Question

In PHP, I want to save messages to a text file and read the log file using php.

Here is what I have so far:

function LogUserActivity($LogFile, $Activity){
    $UserIp = $_SERVER['REMOTE_ADDR'];
    $TimeRef = date('d-m-Y H:i T');

    $Handle = fopen($LogFile, 'a');
    $Data = $UserIp.'|'.$TimeRef.'|'.$Activity.'~';
    fwrite($Handle, $Data);
    fclose($Handle);
}

function ReadUserActivity($LogFile){
    global $log;
    $LogFile = file_get_contents($LogFile);
    $ExplodedLogFile = explode("~", $LogFile);
    $ArrayNum = count($ExplodedLogFile);

    $i = 0;
    while ( $i <= $ArrayNum ){
        $log[$i] = explode("|", $ExplodedLogFile[$i]);
        $i++;
    }
}

Call LogUserActivity at the beginning of every script, passing it the file you want to write to and some message to yourself. E.g.:

<?php
include('the-file-where-you-put-these-functions.php');
LogUserActivity('/tmp/example.log', 'Porkchop sandwitches!');
// the rest of your script
?>

Call the other function in the script you’re gonna use to inspect the logs. It will set the $log variable which you can then print out however you want.

Or just use this single liner:

<?php
file_put_contents("/tmp/stuff.txt", "penguins", FILE_APPEND); 
?>
