Başlıkta anlatamamış olabilirim alttaki kodları yazdım ama bir yerde tıkandım.

Alttaki arrayde olan ucret kısmını "islem_ucret" kısmına yazdırmam laızm.

PHP

$parcalar = array(
array( 'id'=> 1, 'parca'=>'ekran', 'ucret'=>'20' ),
array( 'id'=> 2, 'parca'=>'tuş', 'ucret'=>'30' ),
array( 'id'=> 3, 'parca'=>'zil', 'ucret'=>'50' ),
array( 'id'=> 4, 'parca'=>'film', 'ucret'=>'25' ),
array( 'id'=> 5, 'parca'=>'duy', 'ucret'=>'10' )
);
