如何自动将WordPress文章内容分成三列？

Question

我目前正在使用这篇教程中的以下代码，自动将WordPress文章内容拆分成两列。但是，我要如何改变这段代码以输出3列而不仅仅是2列呢？

functions.php 代码:

function content_split($text, $separator = '<hr/>', $start = false ) {

if ( $start === false) {
$start = strlen($text) / 2;
}

$lastSpace = false;
$split = substr($text, 0, $start - 1);

// if the text is split at a good breaking point already.
if (in_array(substr($text, $start - 1, 1), array(' ', '.', '!', '?'))) {

$split .= substr($text, $start, 1);
// Calculate when we should start the split
$trueStart = strlen($split);

// find a good point to break the text.
} else {

$split = substr($split, 0, $start - strlen($separator));
$lastSpace = strrpos($split, ' ');

if ($lastSpace !== false) {
$split = substr($split, 0, $lastSpace);
}
if (in_array(substr($split, -1, 1), array(','))) {
$split = substr($split, 0, -1);
}

// Calculate when we should start the split
$trueStart = strlen($split);
}
//now we know when to split the text
return substr_replace($text, $separator, $trueStart, 0);

}

index.php代码：

<div class="first-column my-column">
<?php $text = get_the_content(); $separator = '</div><div class="second-column my-column">'; echo apply_filters('the_content', content_split($text,$separator)); ?>
</div>

function content_split($text, $separator = '<hr/>') {

    $string = '';
    $start = ceil(strlen($text) / 3);

    $string.= substr($text,0,$start);
    $string.= $separator;
    $string.= substr($text,$start,$start);
    $string.= $separator;
    $string.= substr($text,($start*2),$start);

    return $string;
}
