php - validate directly in your if or create a function? -

the question kinda hard put in words hope make sense

what's best practice?

this

if($value < 5) {     //do }

or this

if(validvalue($value)) {     //do }  function validvalue($value) {     if($value < 5) return true; }

this best way validate value rather creating function that's not required.

if ( $value < 5 )   {    #do   }
