PHP Array - Return specific elements of array and display them on one line -

i'm ready go crazy one. can't seem figure out how print out elements of array , put results on 1 line (with specific output).

here's array data (after running through foreach statement:

array (     [hostname] => server01     [server_id] => 4     [disk_mountpoint] => /     [disk_datetime] => 1426395600     [disk_device] => /dev/mapper/volgroup00-logvol00     [disk_capacity] => 15g     [disk_used] => 5.3g ) array (     [hostname] => server01     [server_id] => 4     [disk_mountpoint] => /var     [disk_datetime] => 1426395600     [disk_device] => /dev/mapper/volgroup01-logvol00     [disk_capacity] => 107g     [disk_used] => 52g ) array (     [hostname] => server01     [server_id] => 4     [disk_mountpoint] => /opt     [disk_datetime] => 1426395600     [disk_device] => /dev/mapper/volgroup02-logvol00     [disk_capacity] => 156g     [disk_used] => 127g ) 

here's foreach statement:

foreach ($storage_report $item) {                 print_r($item); } 

i've spent couple of hours trying wrap mind around multi-dementional array looking @ other peoples questions on stackoverflow, nothing seems fit i'm trying do.

by way, array above output mysql query , returns 1 unique hostname, has same hostname element, correct (same server_id).

i tried nested foreach loop , didn't work , got confused again, didn't want post here.

basically, data above, want output like:

$disk_mountpoint = $disk_used 

with being said, ultimate output (if parse wrote), final output like:

/ = 5.3g /var = 52g /opt = 127g 

i feel i'm on complicating things , wanted know if point me in right direction , me out.

thanks! drew

um.. just:

foreach ($storage_report $item) {     echo $item['disk_mountpoint'] .'='.$item['disk_used'];  }
