PHP：我们如何创建一个联合的数字关联数组; 我如何自己查找索引？

Question

Here's the generic workaround I am using:

http://codepad.viper-7.com/2tiPvN

$j=0;
$paper = array('copier' => "Copier and Multipurpose",
               'inkjet' => "Injet Printer",
               'laser' => "Laser Printer",
               'photo' => "Photo Paper");

foreach ($paper as $index => $description)
{
  echo "$j, $index: $description
";
  $j++;
}

I want to have numeric identifiers and keyword identifiers.

Meanwhile, because foreach ($paper as $description) gives the description and

foreach ($paper as $index => $description) 

gives the index and then the description..., is there a way to just get the index in a foreach, without having to specify a variable for the description?

Answer 1

not sure what you mean, but maybe

foreach(array_keys($ary) as $key)...
