Split long html into smaller pieces - php

Question

I need to split long html into smaller pieces with respect to tags and inline styles.
E.g. given html
<table>
<tr>
<td style="font-size:12px;">Some long string here</td>
<td style="color: red">Some short string here</td>
<td style="font-weight: bold">Some specific string here</td>
</tr>
</table>
The source of the problem: I've a long html over 50k of chars and I need to translate it via google translate api which has a max limit of 5000 chars per request.

For just splitting it, you can use str_split and iterate the array:
$chunks = str_split($html, 5000);
foreach ($chunks as $chunk) {
// $chunk var is up to 5000 chars long
}
But before, you might want to consider sending it without the HTML part:
$dom = new DOMDocument();
$dom->loadHTML($html);
$text = "";
foreach ($dom->getElementsByTagName('*') as $element) {
$text .= $element->textContent . "\n";
}
Then using the split operation on the $text variable.
For both combined, let's say your input variable is $html:
function htmlToText($html)
{
$text = "";
$dom = new DOMDocument();
$dom->loadHTML($html);
foreach ($dom->getElementsByTagName('*') as $element) {
$text .= $element->textContent . "\n";
}
return $text;
}
$chunks = str_split(htmlToText($html), 5000);
foreach ($chunks as $chunk) {
// dispatch the API operation over $chunk
}
