        )

how to get the [value] alone in php

print $myArray[0]->columns['a21ha:link_0']->value;

This would give you the first. To get all, you'd have to loop through the contents.

foreach ($myArray[0]->columns as $column) {
  print $column->value;
}

Supposed your array called $array:

foreach($array as $arridx => $rowobj){
    foreach($rowobj->columns as $cellid => $rowcell){
        echo $rowcell->value;
    }
}
