php - Bidimensional array generated dynamically -

i'm working dynamic data, i'm trying put data bidimensional array.

i need structure this:

$array['something1'] = array ( 'hi1' => 'there1' , 'hi2' => 'there2' ); 

all data dynamically generated foreach, ex.:

$list = array ( 0 => 'something;hi1;there1' , 1 => 'something;hi2;there2' );   foreach ( $list $key => $data ) {     // extract data     $columns    = explode ( ';' , $data );      // set data     $items[$columns[0]] = array ( $columns[1] => $columns[2] ); } 

how can described?

right script stepping on previous key getting this:

$array['something1'] = array ( 'hi2' => 'there2' ); 

i hope can me.

thanks.

the problem overwriting value key when exists. should modify like:

foreach ( $list $key => $data ) {     // extract data     $columns    = explode ( ';' , $data );     $outer_array_key = $columns[0];     $key = $columns[1];     $value = $columns[2];      // set data     $items[$outer_array_key][$key] = $value; }
