PHP Foreach Loop to Print All Emojis

Question

I see that there's better support of Emojis in PHP 7 but no packaged set/library of emojis to reference from. As of now, I have to search and look for the UNICODE of the emoji I desire at https://apps.timwhitlock.info/emoji/tables/unicode.

Would there be an easier method to obtain every single (latest) Emoji by iterating through a loop rather than referencing an array I would have to build on my own (copying & pasting every UNICODE)?

Answer 1

Try the following:

<?php

$data = file_get_contents("https://apps.timwhitlock.info/emoji/tables/unicode");

$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($data);
libxml_clear_errors();
$finder = new DomXPath($doc);
$nodes = $finder->query("//*[contains(concat(' ', normalize-space(@class), ' '), ' code ')]");
$unicodes = [];
$i = 1;
foreach ($nodes as $node) 
{
if($i % 2 === 0) {$i++;continue;}

    $unicode = trim($node->textContent);
    $unicodes[] = $unicode;
    file_put_contents("unicodes.txt", $unicode. "\r\n", FILE_APPEND);

    $i++;
}

var_dump($unicodes);

It will take all the Unicodes from the site and store it in a file unicodes.txt and in array $unicodes. This simply uses DOMDocument to scrap the page. And Then you can get all of them using:

<?php

$emojis = file("unicodes.txt");

foreach($emojis as $emoji)
{
    $emoji = trim($emoji);
    $emoji = hexdec($emoji);
    echo "&#$emoji;";
}
