I have an array with 100+ elements
Each element is an array of 75 elements
What would be the best way to retrieve a subset of elements from each
the sub-array?
Say I wanted element 2 thru 6, 11 and 42 from each element of the main
array?
How would you go about this?
============
Now to ask the question using terms like 'row' and column'.
Yes, I know, PHP arrays are not rows and columns. They are index arrays
that can hold arrays in each "value" of the array.
I want column 2 thru 6, 11 and 42 from each row.
How would you go about this?
=============
Right now, I pull each element out and stick it in a second array...
$tmpArray = array()
for ( $i = 0; $i < $mainArrayCount; $i++ )
{
$tmpArray [$i][] = $rec[2];
$tmpArray [$i][] = $rec[3];
$tmpArray [$i][] = $rec[4];
$tmpArray [$i][] = $rec[5];
$tmpArray [$i][] = $rec[6];
$tmpArray [$i][] = $rec[11];
$tmpArray [$i][] = $rec[42];
}
Is there a better way?
Thanks
Walter
