遍历文件中的字符串并将值转换为两个单独的数组

Question

Need a quick and easy way to turn a file, into a string I then need to turn the file into two seperate arrays called $username and $password

File Format:

user1:pass1
user2:pass2
user3:pass3

etc. I need the arrays to come out as

$username[0] = "user1";
$password[0] = "pass1";

$username[1] = "user2";
$password[1] = "pass2";

etc

I have already read the file like this:

$file = file_get_contents("accounts.txt");

Answer 1

Read on explode() . However, please note that when your password (or username) contains a colon, this won't work. You might also want to encrypt your password , and also consider using salts in encrypting passwords .

<?php
$file = file_get_contents("accounts.txt");
$file = explode("\n",$file);
$username = array();
$password = array();
foreach ($file as $line) {
    $line = explode(':',trim($line)); // trim removes \r if accounts.txt is using a Windows file format (\r\n)
    $username[] = $line[0];
    $password[] = $line[1];
}

Answer 2

do you mean:

$content = file("config.txt");
$username = array();
$password = array();

foreach($content as $con) {
  list($user, $pass) = explode(":", $con);
  $username[] = $user;
  $password[] = $pass;

}

Answer 3

Your array should look like this instead

$file = file("log.txt");
$users = array();
foreach ( $file as $line ) {
    list($u, $p) = explode(':', $line);
    $users[] = array("user" => trim($u),"password" => trim($p));
}

var_dump($users);

Output

array (size=3)
  0 => 
    array (size=2)
      'user' => string 'user1' (length=5)
      'password' => string 'pass1' (length=5)
  1 => 
    array (size=2)
      'user' => string 'user2' (length=5)
      'password' => string 'pass2' (length=5)
  2 => 
    array (size=2)
      'user' => string 'user3' (length=5)
      'password' => string 'pass3' (length=5)

Answer 4

<?php

$file = "abcde:fghijkl\nmnopq:rstuvwxyz\nABCDE:FGHIJKL\n";

$reg="/([A-Za-z]{5}):([A-Za-z]+\\n)/i";

preg_match_all($reg,$file,$res);

for($i=0;$i<count($res[0]);$i++){
    echo 'usename is '.$res[1][$i].'====='.'passwd is '. $res[2][$i]."<br />";
}

?>

Answer 5

Or you can find the split the string by finding the index of the : :

<?php
//what you would really do
//$file = file_get_contents("accounts.txt");
//just for example
$file = "abcde:fghijkl\nmnopq:rstuvwxyz\nABCDE:FGHIJKL";
$e = explode("\n", $file);
$username = array();
$password = array();
foreach($e as $line) {
    $username[] = substr($line, 0, strpos($line, ':'));
    $password[] = substr($line, strpos($line, ':') + 1);
}
foreach($username as $u) {
    echo $u."\n";
}
foreach($password as $p) {
    echo $p."\n";
}
?>

Output

abcde
mnopq
ABCDE
fghijkl
rstuvwxyz
FGHIJKL
