Problem with Adding info into an array

In making an array: I have 7 checkboxes, which make up the array information. I currently use implode to make the array, however that array only consists of the information that it checked. What I need to do now is make it so the array will always be 7 items, but if there isnt a checkbox for the item, I want inserted to be a 0. Example item1[x] item2[x] item3[ ] item4[x] item5[ ] item6[x] item7[ ] would return = 1,2,0,4,0,6,0 instead of what it does now. 1,2,4,6 I tried placing in the lines before the implode command, saying that: if($array[0]=="") { $array[0]="0"; } else { } if($array[1]=="") { $array[1]="0"; } else { } if($array[2]=="") { $array[2]="0"; } else { } if($array[3]=="") { $array[3]="0"; } else { } if($array[4]=="") { $array[4]="0"; } else { } if($array[5]=="") { $array[5]="0"; } else { } if($array[6]=="") { $array[6]="0"; } else { } But this just made the values of the array become blank. Any suggestions? Thanks in advance, Phillip --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
