Another advanced method is called an ArrayIterator  It   s part of a wider class that exposes many accessible variables and functions  You are more likely to see this as part of PHP classes and heavily object-oriented projects     fnames     Muhammed    Ali    Fatimah    Hasan    Hussein      arrObject   new ArrayObject  fnames    arrayIterator    arrObject- gt getIterator     while   arrayIterator- gt valid      echo  arrayIterator- gt current       lt br   gt     arrayIterator- gt next

I also find that using  lt pre gt  lt  pre gt  tags around your var dump or print r results in a much more readable dump

Additionally  if you are debugging as Tom mentioned  you can use var dump to see the array

either foreach   foreach  array as  key   gt   value         do something with  key and  value     or with for   for  i   0   l   count  array    i  lt   l     i         do something with  array  i      obviously you can only access the keys when using a foreach loop   if you want to print the array  keys and  values just for debugging use var dump or print r

Use a foreach loop  it loops through all the key  value pairs    foreach  array as  key  gt  value        print   key holds  value n        Or to answer your question completely    foreach  array as  value        print  value   n
