title: Get only Numeric values from Array in PHP
body: <p>I have an array that looks something like this:</p>
  
  <pre><code>Array ( 
  [0] =&gt; Array ( [country_percentage] =&gt; 5 %North America ) 
  [1] =&gt; Array ( [country_percentage] =&gt; 0 %Latin America )
  )
  </code></pre>
  
  <p>I want only numeric values from above array. I want my final array like this</p>
  
  <pre><code>Array ( 
  [0] =&gt; Array ( [country_percentage] =&gt; 5) 
  [1] =&gt; Array ( [country_percentage] =&gt; 0)
  )
  </code></pre>
