You can use next simple function:

<?php

function find_text($text) {
    // convert input text to lower case
    $text = strtolower($text);

    // build dictionary with responses on each word 
    $dict = [
        "kde" => "Nikde",
        "kam" => "Nikam",
        "kdy" => "Nikdy",
        "jak" => "Nevim",
        "co" => "Nic",
        "proč" => "Nevim",
        "proc" => "Nevim",
        "kdo" => "Nikdo",
        "koho" => "Nikoho",
    ];

    // loop trough dictionary
    foreach($dict as $find=>$response) {
        if (false !== strpos($text, $find)) {
            // immediately return response when one of dictionary words found 
            return $response;
        }
    }
    // if input cot contains no one of dictionary words return 'not found'
    $text = array("Spíš ne", "Asi", "No nevím");
    return $text[array_rand($text)];
};

// echo find_text('"Kdy prijdes"');

if(isset($_GET['action']))
{
    echo find_text($_POST['textbox']);
}
?>

I would try to find a solution for this using strpos()

so if you check for a specific part of text it could look like this:

if(strpos($text, "Kdy") !== false){
//do something
}

Another approach could be to explode() the $text into its parts and compare the array with an array of strings you want to check for.

But there might be smarter solutions for this.
