yp_match -- Returns the matched line.

## Description

`string yp_match`(string domain, string map, string key);

yp_match() returns the value associated with the passed key out of the specified map or FALSE. This key must be exact.

Example 1. Example for NIS match
    <?php
        $entry = yp_match($domain, "passwd.byname", "joe");

        if(!$entry) {
            echo yp_errno() . ": " . yp_err_string();
        }

        echo "Matched entry is: " . $entry;
    ?>

In this case this could be: joe:##joe:11111:100:Joe User:/home/j/joe:/usr/local/bin/bash
