PHP Array Question

[Battery Powered]

Hi

At the moment im using this to print part of an array

PHP Code:

print (" $values[0] "); 


which works fine, but the value in the '[ ]' i want to be dynamic,
what im trying to do is this

PHP Code:

print (" $values[ $number * 7 + 1 ] "); 


i want the value in the '[ ]' to be a variable multiplied by 7 and then having one added to it

ive tried and tried and cannot get it to work,
any ideas?

Thanks,
James

Hi James,

Try calculating the index outside of the print statement, like this.

PHP Code:

$index = $number * 7 + 1;
print($values[$index]);

Ok i managed it by doing the following if any one is intrested:

PHP Code:


$values = file("data.dat"); 

for($i = 0; $i <= sizeof($values); $i=$i+7) 
  {
     print ("$values[$i] ") ;
  } 


Not sure if any of you are intrested in this, but it gives me my gap of 7 : )

All the best,
James

Why converting to string? I think :

PHP Code:

print ( $values[ $number * 7 + 1 ] ); 


Should work just fine.
