Question

Trying to convert a perl script to php.

In perl I have a hash like this

my %SPEC=(
odmiles           => ['OD Miles','Mileage','odmiles:ecmmiles','num'],
ecmmiles          => ['ECM Miles',0,'','num',' ECM'],
cdl               => ['CDL','CDL']);

I can access the data like so:

$SPEC{ecm}[3]  # output = num

Since a hash in perl does not run in order I’ll do a simple array

@ORD=('odmiles','ecmmiles','cdl');

then loop

foreach my $S (@ORD) {
  print $S." = ".$SPEC{$S}[0]."<br />";
  }

I can do similar with php but having issue accessing elements past [0] in my hash.

I think you’re looking for this:

$SPEC = array(
  'odmiles'           => array('OD Miles','Mileage','odmiles:ecmmiles','num'),
  'ecmmiles'          => array('ECM Miles',0,'','num',' ECM'),
  'cdl'               => array('CDL','CDL')
);

Accessing elements would then work something like this:

echo $SPEC['odmiles'][0]; // 'OD Miles'
echo $SPEC['odmiles'][1]; // 'Mileage'
