title: Check if variable has a number php
body: <p>I want to check if a variable has a number in it, I just want to see if there is one I don't care if it has any thing else in it like so:</p>
  
  <pre><code>"abc" - false
  "!./#()" - false
  "!./#()abc" - false
  "123" - true
  "abc123" - true
  "!./#()123" - true
  "abc !./#() 123" -true
  </code></pre>
  
  <p>There are easy ways of doing this if you want to know that is all numbers but not if it just has one. Thanks for your help.</p>
