php array, to check if a value at key is set or not and update accordingly -


I initialize a php array named $ present, the object of this array is to hold the value of 1 if any name Is present or zero if the name is absent. I have a 10 size name array. Below is the code, but it does not work. 

  $ present = array (); ($ I = 0; $ i & lt; = 10; $ i ++) {if (! Isset ($ present [$ name [$ i]])) {$ present [$ name] = 1; } And $ echo $ attendee [$ name [$ i]]; }   
 I have also tried:  
  $ present = array (); ($ I = 0; $ i & lt; = 10; $ i ++) {If (empty $ $ [$ name]]) {$ present [$ name] = 1; } And $ echo $ attendee [$ name [$ i]]; }   
 Thank you!   
 
 
 I think this may be what you are looking for. You're losing $ i when setting $ 1  
  $ present = array (); ($ I = 0; $ i & lt; = 10; $ i ++) {if (! Isset ($ present [$ name [$ i]])) {$ present [$ name [$ i]] = 1 ; } And $ echo $ attendee [$ name [$ i]]; }
