[Deko]

I'm sure this has been asked before but after some googling I decided I'd ask for help since I'm a novice to php.

Currently I am wanting to find a username and the date in a text file.

Example of text file:

Code

User1 - 2014-07-21
User2 - 2014-07-25

I thought if I used "preg_match_all()" to find the line I would be able to then split the "User" from the "Date" by using another "preg_match_all()" but it seems that the function can't find the text for the user and date.

I thought it would be as easy as this:

Code

$user = "Deko"; //$_POST['u'];
$input = "Deko - 2014-07-21"; //Using a string for testing

preg_match_all('/'.$user.' - !\d+-\d+-\d+!/', $input, $output);
$output = implode(' ', $output[0]);

preg_match_all('/'.$user.'/', $output, $cUser);
$cUser = implode(' ', $cUser[0]);

preg_match_all('!\d+-\d+-\d+!', $output, $cDate);
$cUser = implode(' ', $cDate[0]);

but apparently it isn't. I guess any help is appreciated since I have little to no idea of what I'm doing. Feel free to criticize (no assholes though) and tell me how I can get better.

Is this close to what you want?

PHP Code


<?PHP
$a=file_get_contents('./users.txt');
$b=explode('\n', $a);
for($i=0;isset($b[$i]);$i++)
{
    $c=explode(" - ", $b[$i]);
    $users[]=trim($c[0]);
    $dates[]=trim($c[1]);
}
?>

<?PHP
$a=file_get_contents('./users.txt');
$b=explode('\n', $a);
for($i=0;isset($b[$i]);$i++)
{
    $c=explode("-", $b[$i]);
    $users[]=trim($c[0]);
    $dates[]=trim($c[1]);
}
?>

That might just be it. I'll have to seperate the user and date with '|' as using '-' in the explode would cause the code to skip the month/day of the date.

I'll test it and get back to you. Thank you.

Updated the code, it will fix that problem.

[Deko]

That works too :)

After testing out the code, I can confirm it doesn't work for exactly what I need.

I added:

Code

$v_users = implode(' ',$users);
$v_dates = implode(' ',$dates);

to the code you posted and printed the $v_users and $v_dates, turns out the $users only reads up until the first " - " and the $dates only reads from the " - " to the following " - " (including the next user).

Could you post or PM me the text file you are working with?

Could you post or PM me the text file you are working with?

I've PM'd you. Hopefully this can be solved soon.

<?php 
$users = $dates = array();
foreach(file('file.txt') as $line){
    $exp = explode(' - ',$line);
    $users[] = $exp[0];
    $dates[] = $exp[1];
}

$users = $dates = array();
foreach(file('file.txt') as $line){
    $exp = explode(' - ',$line);
    $users[] = $exp[0];
    $dates[] = $exp[1];
} 


Hmm, I have just realized that this isn't what I want because I'm wanting to search for the 'user' and then the date that's on the same line as the 'user'

Example:

My user is: Deko

Text File:

Code

Subject75 - 2014-07-21
Subject75 - 2014-07-21
Subject23 - 2014-07-22
Subject91 - 2014-07-22
Deko - 2014-07-25
Subject85 - 2014-07-28
Subject34 - 2014-07-29

I want to find 'Deko', once found, grab that line and use that one date as a variable.

PHP Code


<?php 
$user = $_POST['u']
$file = "users.txt"

}

if(isset($users['Deko'])) //to use like $users[$_POST['u']]
    echo $users['Deko']; //date
else
    echo 'No deko :((('; 


This is an associative example, the username will be the key and the date the value

I think is exactly what I wanted. Give me 5 minutes to test and I'll report back :)

EDIT: After testing and changing a few lines to fit my system, I can say that your method works perfectly. Thank you very much!
