正则表达式失败

Question

I have this text:

/**
 * @var \guervyl\cbind_attr_testBundle\Entity\Category
 *
 * @ORM\ManyToOne(targetEntity="guervyl\cbind_attr_testBundle\Entity\Category", inversedBy="song")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="category_id", referencedColumnName="id")
 * })
 */
private $category;

/**
 * @var \guervyl\cbind_attr_testBundle\Entity\User
 *
 * @ORM\ManyToOne(targetEntity="guervyl\cbind_attr_testBundle\Entity\User", inversedBy="song")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="user_id", referencedColumnName="id")
 * })
 */
private $user;

I want to get that part to edit:

* @ORM\ManyToOne(targetEntity="guervyl\cbind_attr_testBundle\Entity\Category", inversedBy="song")
     * @ORM\JoinColumns({
     *   @ORM\JoinColumn(name="category_id", referencedColumnName="id")
     * })
     */
    private $category;

I have that expression that stop on the $: (\*.*@ORM\\ManyToOne\(.*)(\)(?:\s|.)*?private \$)

But when I try to select the rest category;, when I set the c I got no match (timeout): (\*.*@ORM\\ManyToOne\(.*)(\)(?:\s|.)*?private \$c)

I want that regex to work: (\*.*@ORM\\ManyToOne\(.*)(\)(?:\s|.)*?private \$category;)

What's wrong with my Regex?

Answer 1

The matching pattern could be:

.*ManyToOne(.|
)*category;

The pattern means:

.*           Match anything zero or more times
ManyToOne    Literally match "ManyToOne"
(.|
)*      Match anything (including line breaks) zero or more times
category;    Literally match "category;"

The resulting match would be:

 * @ORM\ManyToOne(targetEntity="guervyl\cbind_attr_testBundle\Entity\Category", inversedBy="song")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="category_id", referencedColumnName="id")
 * })
 */
private $category;
