现有 Array[] 中的“for each”PHP 循环

Question

I'm trying to loop an array from a database into an existing array. The two codes work well alone but I only get an error when trying to combine them.... for example...

The current array (which is a list of spammer databases) look as such...

$dnsbl_lookup=array(
"access.redhawk.org",
"all.s5h.net",
"blacklist.woody.ch",   
);

While the array I am trying to add is as so...

$values = $myOptions['re_i_'];
foreach ($values as $value) {
echo '"'.$value['database'].'",';
}

And I end up with the following...

$dnsbl_lookup=array(
"access.redhawk.org",
"all.s5h.net",
"blacklist.woody.ch",   

$values = $myOptions['re_i_'];
foreach ($values as $value) {
echo '"'.$value['database'].'",';
}

);

Which, of course, only returns an error. Does anyone know how to do this properly or if it is even possible?

Answer 1

It looks like you want to merge the $dnsbl_lookup values with the database column values in $myOptions , which you can do with array_merge and array_column :

$dnsbl_lookup = array(
    "access.redhawk.org",
    "all.s5h.net",
    "blacklist.woody.ch"
);
$dnsbl_lookup = array_merge($dnsbl_lookup, array_column($myOptions['re_i_'], 'database'));
