Arrays

Arrays

Ordered arrays

 <?
$a[0] = 1;
$a[1] = "foo";
$a[]  = 1.57;
?>

String-indexed arrays

 <?
$catch_it['cat'] = "mouse";
$catch_it['dog'] = "cat";
?>

Array example (a faster way to compute Fibonacci numbers):

<html> <body> <?php $F[0] = 0; $F[1] = 1; // Fill in the entries of the array: for ( $i = 2; $i < $N; $i++ ) $F[$i] = $F[$i-1] + $F[$i-2]; // Print out the array: for ( $i = 0; $i < $N; $i++ ) print( " $F[$i]" ); ?> </body> </html>

Try it here with N=13.
Try it here with N=1000.

See the references for more information on arrays. In PHP, they can do a lot of "surprising" things...
