ARRAY DECLARATION IN PHP

I want to create an array, but its size depends on how many records a file has. So i want to READ a file and after counting how many records it has i want to initialize that array. What's the best way to do this?
Use an array based on a pointer, load the array from the file then allocate the right size of the array to the pointer. That is :

PHP Code:

D MyArray     DS       

        Dim(9999) Based(p_My Array)

 

     p_MyArray = Alloc(Size(Myarray) * 9999);   // Load the array from the file
    
     Do U EOF();
      Read File ...
       ...                                        // Count # of entries
     
      MyArray_Cnt += 1;                             // Loop

     
     End do;                                      // Reallocate the size of the array
    
     p_MyArray = %Realloc(p_MyArray : %size(MyArray) * MyArray_Cnt);
     ...                                               // End of Program
  
    Dealloc p_MyArray;
    InLR = *On;  


1/ Example WITHOUT qualified

PHP Code:

D Arr             ds                     Based(p_Arr)                D  ArrEntry                     10a      Dim(999)                   D   ArrFld1                      3a      Overlay( ArrEntry : *Next )D   ArrFld2                      7a      Overlay( ArrEntry : *Next )
...D ArrCnt          s             10i 0   inz        
                                                   
 /free                                             
   p_Arr = %Alloc(%Size(ArrEntry) * 9999);// Load the array from the file               
                 
   Do U EOF();                                   
     Read File ...
     If EOF();
        Leave;
     Else                                // Count # of entries         
                      
       ArrCnt = +1;                         // Load the array
     
       ArrFld1(ArrCnt) = Fld1;
       ArrFld2(ArrCnt) = Fld2;                            
       ...                                        
      End If;                        
   End do;     
                     
                        
   p_Arr = %Realloc(p_Arr : %size(ArrEntry) * ArrCnt);// Reallocate the size of the array   
   ...                                               // End of Program                                
 
                                                     Dealloc p_Arr; 
  *inlr = *on;  

2/ Example WITH qualified 

PHP Code:

D Arr_Template    ds                    Qualified        
D  Fld1                          ...                         D  Fld2                          ...        
...                                                         D Arr             ds                    Based(p_Arr)        D                                       Dim(9999)           D                                       Likeds(Arr_Template)
                                                    D ArrCnt          s             10i 0   inz      
                                                 
 /free                                           
  p_Arr = %Alloc(%Size(Arr) * 9999);             
  Do U EOF();                                   
    Read File ...
    If EOF();
       Leave;
    Else                   // Count # of entries
    
       ArrCnt += 1;               // Load the array   
                  
      Arr(ArrCnt).Fld1 = Fld1;            
      Arr(ArrCnt).Fld2 = Fld2; 
      ... 
    End If;    
  End Do;   
                                  
 
   p_Arr = %Realloc(p_Arr : %size(Arr) * ArrCnt);// Reallocate the size of the array  
   ...                                          // End of Program  
                                                   
                               
  Dealloc p_Arr;
  *inlr = *on;
