txt file

111111 Nome Sobrenome
222222 Nome Sobrenome
333333 Nome Sobrenome

Field to fill

<span>Aluno</span> : <input id="entry" type="text" name="test">

How do I get it done so that when the user type the auto name or license plate complete (searching the.txt file) and save in $license plate only with the number plate?

The number plate may vary the number of characters, but always appears at the beginning.

Is it possible? Someone can help me?

You have to study the functions of PHP guy, for example, instead of asking here, you can go on Google and type: "how to split a string" which is "how to split/cut a string", will come the function explode() for example, then you implement. Another thing: "how to get content from a txt file" which is "how to get content from a txt file" from there in the PHP documentation will appear file_get_contents().

Example:

<?php
$contents = file_get_contents("file.txt");

$rows = explode("\n", $contents);
$cols = [];
foreach ($rows as $row) {
  $cols[] = explode(" ", $row);
}

Now you have an array +/- like this:

[
  ["1", "Marcelo", "Rafael"],
  ["2", "Ana",     "Clara"],
  ["3", "Berta",   "Jota"]
]

Now, since Voce wants to autocomplete, Voce should use Ajax, so only study if you don’t know. Sites to learn:

W3 is more practical and fast
W3schools Ajax

or MDN which is more "updated"
MDN Ajax

I didn’t answer your question directly, but I’m here to help, flw.
