Use function to compare value and mark radio buttom

Question

I need to create a function to compare value and mark radio buttom.

$checklistIni = unserialize($row_rsRegistros['checklistIni']);
$a = join(',', array_values($checklistIni));

function compara($valor) {
    $array = explode(",", $a);
    if(in_array($valor, $checklistIni)) {
        return "checked";
    }
}

And then use right where I need to make the comparison.

<tbody>
   <tr>
        <td class="texto-branco">Documento</td>
        <td><label><input value="tem" <?php echo compara("tem"); ?>  name="checklistFim0" class="checklistFim" type="radio" /><span></span></label></td>
        <td><label><input value="nao" <?php echo compara("nao"); ?>  name="checklistFim0" class="checklistFim" type="radio" /><span></span></label></td>
        <td><label><input value="ava" <?php echo compara("ava"); ?>  name="checklistFim0" class="checklistFim" type="radio" /><span></span></label></td>
    </tr>
        <tr><td class="texto-branco"> Manual </td>
        <td><label><input value="tem" <?php echo compara("tem"); ?>  name="checklistFim1" class="checklistFim" type="radio" /><span></span></label></td>
        <td><label><input value="nao" <?php echo compara("nao"); ?>  name="checklistFim1" class="checklistFim" type="radio" /><span></span></label></td>
        <td><label><input value="ava" <?php echo compara("ava"); ?>  name="checklistFim1" class="checklistFim" type="radio" /><span></span></label></td>
    </tr>
        <tr><td class="texto-branco">Vidro eletrico </td>
        <td><label><input value="tem" <?php echo compara("tem"); ?>  name="checklistFim2" class="checklistFim" type="radio" /><span></span></label></td>
        <td><label><input value="nao" <?php echo compara("nao"); ?>  name="checklistFim2" class="checklistFim" type="radio" /><span></span></label></td>
        <td><label><input value="ava" <?php echo compara("ava"); ?>  name="checklistFim2" class="checklistFim" type="radio" /><span></span></label></td>
    </tr>
        <tr><td class="texto-branco">Radio/CD </td>
        <td><label><input value="tem" <?php echo compara("tem"); ?>  name="checklistFim3" class="checklistFim" type="radio" /><span></span></label></td>
        <td><label><input value="nao" <?php echo compara("nao"); ?>  name="checklistFim3" class="checklistFim" type="radio" /><span></span></label></td>
        <td><label><input value="ava" <?php echo compara("ava"); ?>  name="checklistFim3" class="checklistFim" type="radio" /><span></span></label></td>
    </tr>

You need to pass the index of the list of values you want to test in order to compare. See:

$checklistIni = unserialize($row_rsRegistros['checklistIni']);

function compara($array, $index, $valor) {
    if(isset($array[$index] && $array[$index] == $valor)) {
        return "checked";
    }
    return '';
}

// printar o atributo checked SOMENTE se o primeiro item da listagem for "tem"
<input value="tem" <?php echo compara($checklistIni, 0, "tem"); ?> />

The above example assumes that the function result unserialize is an array with numeric indices. If the result is an associative array, simply swap the variable declaration $checklistIni for:

$checklistIni = array_values(unserialize($row_rsRegistros['checklistIni']));
