Attention!!!

You have a circular link in your code !!! When you add a tag to a blog, it causes the blog to be added for tags, etc. Please correct it as follows:

The blog

/**
 * Add tags
 *
 * @param \Acme\MainBundle\Entity\tag $tags
 * @return Blog
 */
public function addTag(\Acme\MainBundle\Entity\tag $tags)
{
    if (!$this->tags->contains($tags))
    {
        $this->tags[] = $tags;
        $tags->addBlog($this);
    }

    return $this;
}

Tag

/**
 * Add blogs
 *
 * @param \Acme\MainBundle\Entity\blog $blogs
 * @return Tag
 */
public function addBlog(\Acme\MainBundle\Entity\blog $blogs)
{
    if (!$this->blogs->contains($blogs))
    {
        $this->blogs[] = $blogs;
        $blogs->addTag($this);
    }


    return $this;
}

According to your question:

class TagFixtures  extends AbstractFixture implements OrderedFixtureInterface {

    /**
     * Load data fixtures with the passed EntityManager
     *
     * @param \Doctrine\Common\Persistence\ObjectManager $manager
     */
    function load(ObjectManager $manager)
    {
        $tag1 = new Tag();
        $tag1->setTag("tag name 1");
        $tag1->setIsPublished(true);

        $tag2 = new Tag();
        $tag2->setTag("tag name 2");
        $tag2->setIsPublished(true);
