[RESOLVED] NOOB, I Need To Place A Unit After Some Math....

[iGeekiHackiMatt]

Okay So I Am Okay With PHP Because When I Need A Code I Cannot Think Of/Haven't Heard Of I Can Use Google, Look At Some Peoples Code And Usally Make It Work With My Project. But I Cannot Figgure This Out Because When Ever I Try To Google It I Get Excel Info Not PHP, So Here Is My Code

$ConWidth = ($Width - $LinkWidth); 

I Want To Set It To Something Like This

$ConWidth = ($Width - $LinkWidth) + 'px'; 

so I Can be like

echo"$ConWidth"; 

And It will echo 500px or what ever the answer is with the px after it,
Thank You So Much, Sorry Imma Noob
