change array sructure

Hi All, I have an array made up of records from a db $garm_meas in the form $garm_meas[0] = array $garm_meas[0][0] = company1 $garm_meas[0][1] = size1 $garm_meas[0][2] = meas_name1 $garm_meas[0][3] = meas_value1 $garm_meas[1] = array $garm_meas[1][0] = company1 $garm_meas[0][1] = size1 $garm_meas[0][2] = meas_name2 $garm_meas[0][3] = meas_value2 I want to change the array (or create a new one) in the form $garm_meas[0] = company1 $garm_meas[0][0] = size1 $garm_meas[0][0][0] = meas_name1 $garm_meas[0][0][1] = meas_value1 $garm_meas[0][1] = size2 $garm_meas[0][1][0] = meas_name2 $garm_meas[0][1][1] = meas_value2 $garm_meas[1] = company2 I have got myself bogged down in a really ugly set of nested whiles and fors, can anyone point back in the right direction?
