Can anyone help me to achieve this?

Any help will be appreciated.

Answer 1

Use this code:

<?php
    $command = 'php /path-to-magento-root-directory/bin/magento cache:clean && php /path-to-magento-root-directory/bin/magento indexer:reindex';
    echo '<pre>' . shell_exec($command) . '</pre>';
?>

It will do the task and will produce this output:

Cleaned cache types:
config
layout
block_html
collections
reflection
db_ddl
eav
customer_notification
full_page
config_integration
config_integration_api
translate
config_webservice

Assuming your file is in magento root folder. Add the below code.

error_reporting(1);
ini_set('max_execution_time', 0);

use \Magento\Framework\App\Bootstrap;

require __DIR__ . '/app/bootstrap.php';
$bootstrap = Bootstrap::create(BP, $_SERVER);
$objectManager = $bootstrap->getObjectManager();

//for reindex.
$IndexerFactory = $objectManager->get('Magento\Indexer\Model\IndexerFactory');
$CollectionFactory = $objectManager->get('Magento\Indexer\Model\Indexer\CollectionFactory');

$indexerCollection = $CollectionFactory->create();
   $ids = $indexerCollection->getAllIds();
foreach ($ids as $id) {
   $idx = $IndexerFactory->create()->load($id);
   $idx->reindexAll($id); // this reindexes all
   //$idx->reindexRow($id); // or you can use reindexRow according to your need
}

// for clear cache 
$cacheTypeList = $objectManager->get('Magento\Framework\App\Cache\TypeListInterface');
$cacheFrontendPool = $objectManager->get('Magento\Framework\App\Cache\Frontend\Pool');
$types = array('config','layout','block_html','collections','reflection','db_ddl','eav','config_integration','config_integration_api','full_page','translate','config_webservice');
foreach ($types as $type) {
    $cacheTypeList->cleanType($type);
}
foreach ($cacheFrontendPool as $cacheFrontend) {
    $cacheFrontend->getBackend()->clean();
}

Backticks can be used in PHP to execute shell commands:

<?php

`/var/www/magento2/bin/magento cache:flush && /var/www/magento2/bin/magento indexer:reindex`;

You can prepend it with echo to show the output in your browser.

However, note that executing shell scripts in your php scripts with either backticks, exec() or shell_exec() is considered bad practice.
