Question

Let say i want to read a text file using php.

Now my text file contain

User=Test
Age=18
Gender=F

User=Test2
Age=34
Gender=M

and following like that.

Now let say i want to use php to read the text file and find only value of User= and display it.

What is the easiest way to accomplish this?

Thank you.

Answer 1

$filename = "users.txt";

$user_file_array = file($filename, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);

//Now you have an array of each line of the file.

foreach($user_file_array as $user_info) {
     if(strpos($user_info, "User=") !== false) {
           $users[] = str_replace("User=", "", $user_info);
      }
}

The above assumes that each bit of info is on a new line, that User= is case-sensitive, and that you are okay with looping through whole file. You will get an array returned of just the user names on the right-side of the User=.

If you want that to be echoed out in a column, either change the bit where the $users array gets built, or add this to the end:

 echo implode("\n" $users);
