How to connect PHP sentences/Statements

[CetiN]

When we are using HTML + PHP, say we want to output something like "Skill5" where "5" is load from php variable $number, we can do the following thing:\[code\]Skills<?php echo $number;?>\[/code\]However, right now I want to do the same thing in PHP, I have a sentence like the following:\[code\]if($skills and $skills->skill5){}\[/code\]Where I want to load the number 5 from $variable $number too.So I tried the following thing:\[code\]if($skills and $skills->skill.$number){}\[/code\]However, this is not working. this $number is working as "null" here even it's set to 5.Any ideas?Thank you very much!
