A friend of mine helped with a code, but I'm having a hard time understanding what some lines do, can anyone help me? The rows I am not able to understand have a "<
<?php
echo "<body background=\"fundo2.jpg\">";
echo "</body>";
$linhas = file("senhas.txt");
$quant = count($linhas)-1; <<
if (!isset($_GET['linha'])) { <<
$i = 0;
echo "<h3>";
echo "<font size='5' face='verdana' color='white'>";
echo "Chamar Proxima Senha <a href='?linha=1'>>>CLIQUE
AQUI<<</a>"; <<
echo "</font>";
echo "<hr>";
echo "</h3>";
} else {
$i = $_GET['linha']; <<
if($i==$quant){ <<
}else{
echo "<h3>";
echo "<font size='5' face='verdana' color='white'>";
echo "Chamar Proxima Senha <a href='?linha=" . ($i+1) .
"'>>>CLIQUE AQUI<<</a>";; <<
echo "</font>";
echo "<hr>";
echo "</h3>";
}
}
echo " <font size='5'color='white'><center>Senha</br>
<font size='6' face='arial black' color='red'>
".$linhas[$i];
echo "</br></font>dirija-se ao caixa de atendimento</font>
</center>";
?>
