I want to extract the values in the good_id: 27 and 277, and how to write? Tried the great god recommended way:
1: $aa=$_POST [' good_xinxi];
Foreach ((array) $aa as $v) {
Echo $v [' good_id]}
////////////////////////////////
2: $aa=$_POST [' good_xinxi];
$bb=array_column ((array) $aa, 'good_id')
Echo $bb;
/////////////////////////////////////
3: $aa=$_POST [' good_xinxi];
Foreach ((array) $aa as $v) {
Echo $v - & gt; Good_id; }
//////////////////////////////////////
[all of the above methods can't]
Tried to print: var_dump ($_POST [' good_xinxi ']);
Display content is as follows:
