Creating row using php loop - php

Question

I want to create a row if columns greater than 3 using PHP loop because i am using wordpress
My code is here
<div class="row">
<div class="column">column1</div>
<div class="column">column2</div>
<div class="column">column3</div>
</div>
If columns are greater than 3, then it should create a new row like this
<div class="row">
<div class="column">column1</div>
<div class="column">column2</div>
<div class="column">column3</div>
</div>
<div class="row">
<div class="column">column1</div>
</div>
Any help will be highly appreciated.
Thanks in advance

Answer 1

Sure - just use modulus:
<?php
$elements = array('foo', 'bar', 'rab', 'oof');
echo '<div class="row">';
foreach ($elements as $i => $element) {
if ($i > 0 && $i % 3 == 0) {
echo '</div><div class="row">';
}
echo '<div class="column">' . $element . '</div>';
}
echo '</div>';
?>
DEMO
Output:
<div class="row">
<div class="column">foo</div>
<div class="column">bar</div>
<div class="column">rab</div>
</div>
<div class="row">
<div class="column">oof</div>
</div>

Answer 2

You need something like this:
<?
echo '<div class="row">';
for ($i=0; $i<15;$i++){
if ($i%3 == 0 && $i != 0){
echo '</div><div class="row">';
}
echo '<div class="column">column '.($i+1).'</div>';
}
echo '</div>';
?>

There is alternative solution with function.
<?php
// Managing the Code -- Functions: Handling a Variable Number of Parameters
// building a row of 10 <td> columns with a variable number of items
function preferencesRow()
{
// initialize $output
$output = '';
// use "func_get_args()" to collect all parameters into an array
$params = func_get_args();
// used to make sure 10 columns are filled
$maxCols = 10;
// loop through the parameters
foreach ($params as $item) {
$output .= "<td width='80px' align='center'>$item</td>\n";
$maxCols--;
}
// fill in the rest of the row with empty columns
for ($x = 0; $x < $maxCols; $x++) {
$output .= "<td width='80px'> </td>\n";
}
return $output;
}
// NOTE: you can use "." or "," with echo
echo '<h1>Preferences</h1><hr />' . PHP_EOL;
echo '<table border=1>' . PHP_EOL;
echo '<tr><th>Tarzan</th>';
echo preferencesRow('Africa', 'jungles', 'tantor', 'mangani', 'cabin in the woods',
'hunting', 'swinging in trees', 'Jane');
echo '</tr>';
echo '<tr><th>Jane</th>';
echo preferencesRow('London', 'parties', 'dancing', 'social events', 'lavish estates');
echo '</tr>';
echo '</table>' . PHP_EOL;
