How can I do a Line break - php

Question

How can I do a line break every 5 scores? I have the following code but it shows me all the results in one line, and it needs to start a new line every 5 scores, without using a table.
<?php session_start();
include ("conexion.php");
?>
<?php
$correo=$_SESSION['s_username'];
$sql ="SELECT nombre_catalogo FROM catalogos WHERE email = '$correo'";
$res=mysqli_query($conexion,$sql);
echo "<table border='1' cellpadding='4' cellspacing='0'>";
$fecha = array();
while ($row20 = mysqli_fetch_array($res)) {
$fecha[] = $row20['nombre_catalogo'];
}
echo "<tr>";
echo "<td>Name</td>";
foreach($fecha as $fec) {
echo "<td>" . $fec . "</td>";
echo "<td>" . $fec . "</td>";
}
?>
For example, If I have 13 scores on my db it shows me one line like
*************
But its needs to be this way

Answer 1

array_chunk can be a solution.
while ($row20 = mysqli_fetch_array($res)) {
$fecha[] = $row20['nombre_catalogo'];
}
$fecha = array_chunk($fecha, 5);
foreach($fecha as $data)
{
foreach($data as $fec)
{
echo $fec;
}
# echo implode('', $data); // implode also can be used instead of nested loop.
echo '</br>';
}

You are looking for str_split() PHP DOC
See my example here:
<?php
$string = "0123456789ABCDEF";
// split the string every 5 chars, return as array
$result = str_split($string, 5);
// now create new string by imploding, with linebreak as glue
$result1 = implode(PHP_EOL, $result);
// OR
$result2 = implode("\r\n", $result);
print_r($result1);
print_r($result2);
?>
