Convert list into an array using php. How?

I have a function called listelements(), which outputs text like <li>text1</li><li>text2</li>.

I have more than 500 elements. Now I want to convert it into an array.

Can anyone help me? Thanks.

Note: I'm using php

Update:

The thing i want to achieve is alphabetical navigation. As of now my function displays links in list order. Instead of that i want to hold that in an array. Then i would like to filter them using characters. 

$valid_characters = range( 'a' , 'z' );
$valid_numbers = array(1,2,3,4,5,6,7,8,9,0);

When the user click "A" i would like to display only links start with A. Hope this explanation helps you guys for better understanding my question

you can use simple_html_dom https://simplehtmldom.sourceforge.io/manual.htm

require_once(./simple_html_dom.php);
$html = "<ul class=''><li class=''>Swagger transforms unfreshmen into legends of confidence</li><li class=''>Red Zone collection</li><li class=''>Enhances awesomeness</li><li class=''>Continue your confidence with Swagger Anti-perspirant & Deodorant and Body Spray</li><li class=''>Old Spice Red Zone Swagger Scent Men’s Bar Soap</li></ul>";

$result = li_to_array($html);
var_dump($result ); 

    
function li_to_array($str)
{
    if (is_string($str) && !empty($str)) {
        $html = str_get_html($str);
        $results= array();
        $response_results = $html->find('li');
        foreach ($response_results as $response_result){
            array_push($results, $response_result->plaintext);
        } 
        unset($html); //release memory

        return  $results;
    } else {
        return false;
    }
}

explode won't do the trick nicely for html tags (considering them as multiple delimiters).

if CPU time is not a concern, try using preg_match, example below:

<?PHP

$input='<li>text1</li><li>text2</li><LI><p>text3</p></lI><Li>text fou4r</li>';

preg_match_all('(<(li|Li|LI|lI)>(.*)</(li|Li|LI|lI)>)siU', $input, $output);

print_r($output[2]);
?>


output: 

Array

    (

        [0] => text1
        [1] => text2
        [2] => <p>text3</p>
        [3] => text fou4r
    )

$strarr=explode("<li>",$string); //Breaks every <li>
$i=(-1); //Makes -1 as array starts at 0
$arr=array(); //this will be your array
foreach($strarr as $expl){ //Go through all li's
$ai=explode("</li>",$expl);//Get between the li. If there is something between </li> and <li>, it won't return it as you don't need it
if($i!=(-1))$arr[$i]=$ai[0]; //First isn't valid
$i=$i+1; //add i plus one to make it a real array
}

Use "preg_match".

Here is more detail: http://www.php.net/manual/en/function.preg-match-all.php

<?php
$output = listelements();
$array = explode("<li>", $output);

//First element will be empty, so remove it
unset($array[0]);

// Now remove "</li>" at end of input
array_walk($array, create_function('&$val', '$val = str_replace("</li>", "", $val)'));

// $array should now contain your elements
