php - How do i multiply values of an array -


i error message "array_product() expects parameter 1 array, string given in..." when try multiply values in foreach statement below. kindly help. in advance

here code. note values in $answer "1.50 real(yes)". need "1.50" many in loop multiply , total.

foreach($_post['gm'] $key => $answer){     if($answer != ''){     $odd=explode(" ",$answer);     $od=trim($odd[0]); } $total = array_product($od); echo $total;

i try multiplication outside loop above $total. not repeat in loop. please?

you not reconstructing array in foreach loop. $od variable overridden each time loop.

your code should be

foreach($_post['gm'] $key => $answer) {     if($answer != '') {         $odd = explode(" ",$answer);         $od[] = trim($odd[0]);     } } $total = array_product($od); echo $total;
