try it :
<?php
$file_handle = fopen("db_config.txt", "r");
$ser = array();
$i = 0;
while (!feof($file_handle)) {
$ser[$i] = fgets($file_handle);
$i++;
}
fclose($file_handle);
$servername = $ser[0];
$servername = explode("=", $servername);
$servername = trim($servername[1]);
$username = $ser[1];
$username = explode("=", $username);
$username = trim($username[1]);
$password = $ser[2];
$password = explode("=", $password);
$password = trim($password[1]);
$Conn_Succ_Msg = $ser[3];
$Conn_Succ_Msg = explode("=", $Conn_Succ_Msg);
$Conn_Succ_Msg = trim($Conn_Succ_Msg[1]);
$servername = $servername;
$username = $username;
$password = $password;
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo $Conn_Succ_Msg;
?>
open file and get line and expload line with = and trim for remove spaces .
also you can using expload and trim in while :
$file_handle = fopen("db_config.txt", "r");
$ser = array();
$i = 0;
while (!feof($file_handle)) {
$ser[$i] = fgets($file_handle);
$sers = explode("=", $ser[$i]);
$ser[$i] = trim($sers[1]);
$i++;
}
fclose($file_handle);
$servername = $ser[0];
$username = $ser[1];
$password = $ser[2];
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo $ser[3];
