title: PHP Laravel Convert array value to upper case
body: <p>I have an array with multiples values in my Laravel project:</p>
  
  <pre><code>array:1434 [▼
    0 =&gt; array:53 [▼
      "contact" =&gt; "ANA (dependienta)"
      "mail" =&gt; "example@mail.com"
      "phone2" =&gt; ""
      "phone3" =&gt; ""
      "web" =&gt; "0"
      "active" =&gt; true
      "province" =&gt; "Zaragoza"
  
    ]
    1 =&gt; array:53 [▼
      "contact" =&gt; "JACKELINE * VIVIANA"
      "mail" =&gt; "mail@example.com"
      "phone2" =&gt; ""
      "phone3" =&gt; ""
      "web" =&gt; "0"
      "active" =&gt; true
      "province" =&gt; "Barcelona"
  
    ]
  </code></pre>
  
  <p>I want transform to upper case only the province value, I want to get this result:</p>
  
  <pre><code>array:1434 [▼
    0 =&gt; array:53 [▼
      "contact" =&gt; "ANA (dependienta)"
      "mail" =&gt; "example@mail.com"
      "phone2" =&gt; ""
      "phone3" =&gt; ""
      "web" =&gt; "0"
      "active" =&gt; true
      "province" =&gt; "ZARAGOZA"
  
    ]
    1 =&gt; array:53 [▼
      "contact" =&gt; "JACKELINE * VIVIANA"
      "mail" =&gt; "mail@example.com"
      "phone2" =&gt; ""
      "phone3" =&gt; ""
      "web" =&gt; "0"
      "active" =&gt; true
      "province" =&gt; "BARCELONA"
  
    ]
  </code></pre>
  
  <p>Exists any method or way to make this with Laravel Collection or other alternatives?</p>
