Paypal IPN, Not getting all the transactions responses

I am implementing ipnlistner inside my project. I set the ipn url inside my paypal account. But i am not getting all the transaction ipn responses to that url. But when i am checking ipn history in my account it displays that all the ipn has been sent. For example yesterday it is showing all 112 ipn had sent. but i am getting only 7 in my db. Here is my code for ipn listner. I am inserting all the data i am getting in the db at the first line only.

<?php

namespace App\Http\Controllers;

use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Response;

class PaypalIPN extends Controller {

private $use_sandbox = null;

const VALID = 'VERIFIED';

const INVALID = 'INVALID';

public function useSandbox() {
    $this->use_sandbox = env( 'USE_SANDBOX' );
}

public function getPaypalUri() {
    if ( $this->use_sandbox ) {
        return env( 'SANDBOX_VERIFY_URI' );
    } else {
        return env( 'VERIFY_URI' );
    }
}

public function verifyIPN() {
    try {
        DB::table( 'ipn_response' )->insert( [ 'data' => json_encode( $_POST, true ) ] );
        if ( ! count( $_POST ) ) {
            throw new \Exception( "Missing POST Data" );
        }
        $raw_post_data  = file_get_contents( 'php://input' );
        $raw_post_array = explode( '&', $raw_post_data );
        $myPost         = array();
        foreach ( $raw_post_array as $keyval ) {
            $keyval = explode( '=', $keyval );
            if ( count( $keyval ) == 2 ) {
                // Since we do not want the plus in the datetime string to be encoded to a space, we manually encode it.
                if ( $keyval[0] === 'payment_date' ) {
                    if ( substr_count( $keyval[1], '+' ) === 1 ) {
                        $keyval[1] = str_replace( '+', '%2B', $keyval[1] );
                    }
                }
                $myPost[ $keyval[0] ] = urldecode( $keyval[1] );
            }
