Does a WordPress post already exist?

I’m having a bit of a problem in WordPress. I’m looping through a set of data and creating new posts. I need a way to only create the post if its already not exists.

I tried this, but figured it was a quite stupid idea. But can i do something similar? I cant check the titles, since they in many cases will be the same. Can i do the check on import_id somehow? If i do $post_id->import_id its undefined..

Current code:

 for($i = 0; $i < count($postdata); $i++) { //array of data.

    $id = rand(1000, 9999);

    if(is_null(get_post($id))) {
      $post_id = wp_insert_post(array(
        'import_id' => $id, //number
        'post_status' => $post_status, //string
        'post_type' => $post_type, //string
        'post_title' => $post_title, //string
        'post_content' => $post_content //string
      ));
    }
  }

    You can use the get_post_status() function to tell if a post exists. It will return false if the post does not exist:

    if ( get_post_status( $id ) ) {
    // do stuff
}

    With your example:

    for($i = 0; $i < count($postdata); $i++) { //array of data.

    $id = rand(1000, 9999);

    if ( get_post_status($id) ) {
        $post_id = wp_insert_post(array(
          'import_id' => $id, //number
          'post_status' => $post_status, //string
          'post_type' => $post_type, //string
          'post_title' => $post_title, //string
          'post_content' => $post_content //string
        ));
    }

    You can use post_exists() it will check based on title. check the code below.

    for($i = 0; $i < count($postdata); $i++) { //array of data.

    $id         = rand(1000, 9999);
    $fount_post = post_exists( $post_title );

    if( !$fount_post ) {

        $post_id = wp_insert_post( array(
            'import_id'    => $id, //number
            'post_status'  => $post_status, //string
            'post_type'    => $post_type, //string
            'post_title'   => $post_title, //string
            'post_content' => $post_content //string
        ) );

    }

}

    Update as per OP code.

    $events       = json_decode($res,true);
$this->events = $events['Result'];  
$postdata     = array();
$index        = 0;

foreach($this->events as $key=>$event) {
    $post_status = 'publish';
    $post_type = EVENTS_CALENDAR_POST_TYPE;
    $post_title = $event['Heading'];
    $post_content = $event['Description'];
    $post_image = $this->media_url . $event['ImageLarge']['Path'];
    $post_thumb = $this->media_url . $event['Image']['Path'];
    $post_event_id = $event['Id'];

    foreach($this->events[$key]['Dates'] as $date) {
        $post_date = substr($date['Date'], 0, 10);
        $post_arena = $date['Arena']['Name'];
        $postdata[$index]['id'] = $index;
        $postdata[$index]['status'] = $post_status;
        $postdata[$index]['posttype'] = $post_type;
        $postdata[$index]['date'] = $post_date;
        $postdata[$index]['arena'] = $post_arena;
        $postdata[$index]['heading'] = $post_title;
        $postdata[$index]['desc'] = $post_content;
        $postdata[$index]['image'] = $post_image;
        $postdata[$index]['thumb'] = $post_thumb;
        $index++;
    }
}

for($i = 0; $i < count($postdata); $i++) { //array of data.

    $id = rand(1000, 9999);
    
    $args = array(
       'meta_key' => 'post_event_id'
       'meta_query' => array(
           array(
               'key' => 'post_event_id',
               'value' => $post_event_id,
               'compare' => '=',
           )
       )
    );

    $event = new WP_Query( $args );

    if( !$event->have_posts() ) {

        $post_id = wp_insert_post( array(
            'import_id'    => $id, //number
            'post_status'  => $post_status, //string
            'post_type'    => $post_type, //string
            'post_title'   => $post_title, //string
            'post_content' => $post_content, //string
            'meta_input'   => array(
                'post_event_id' => $post_event_id,
            )
        ) );

    }
