如何通过php动态获取mysql字段

Question

In php I access results from a mysql query results set as such:

$results->fldname;

My question is how can I dynamically pass the field name to $results? For example:

$results->fld_$name;

Answer 1

try this:

$results->{'fld_'.$name};
//or (not recommended)
$name = 'fld_'.$name;
$results->$name;
