Here is one way that works with PHP 7.2+:
<?php
$words = rtrim('php, codes, php, script, php, chat.',".");
$exploded = explode(", ",$words);
$arrCount = array_count_values($exploded);
var_dump($arrCount);
live code: https://3v4l.org/BNXjf
The code trims off the period punctuating the string. Then it explodes the string into the array $exploded using a 2-character string composed of a comma followed by a space character. Then the code defly uses the PHP 7 function array_count_values which creates a new array in this case $arrCount and this array’s keys are the values of $exploded and its values are the number of times each value appears in $exploded as the var_dump() of $arrCount reveals.
