php - How to replace value inside an array? -

i have array shown below.

array (size=2)     '1s1' =>       array (size=8)         'order_id' => int 0         'item_id' => int 1         'special_desc' => string 'special xxx' (length=11)         'qty' => int 2         'price' => int 50         'amount' => int 0         'created_at' => int 1376580193         'updated_at' => int 1376580193     '1s2' =>       array (size=8)         'order_id' => int 0         'item_id' => int 2         'special_desc' => string 'special yyy' (length=11)         'qty' => int 3         'price' => int 150         'amount' => int 0         'created_at' => int 1376580193         'updated_at' => int 1376580193 

if wanted replace "order_id" of both elements of array new value before saving database, array function or technique can use?

thanks.

take @ array_walk:

$array = array_walk( $array, function( $subarray ) {     $subarray[ 'order_id' ] = 'somenewvalue'; } ); 

a simple foreach work too.

// noting '&' reference call foreach( $array &$subarray ) {     $subarray[ 'order_id' ] = 'somenewvalue'; } // or foreach( $array $key => $value ) {    $array[ $key  ][ 'order_id' ] = 'somenewvalue'; }
