Placing SQL query results into one array - php

Question

I have this PhP script:
<?php
$gregorianMonth = date(n);
$gregorianDay = date(j);
$gregorianYear = date(Y);
$jdDate = gregoriantojd($gregorianMonth,$gregorianDay,$gregorianYear);
$hebrewMonthName = jdmonthname($jdDate,4);
$hebrewDate = jdtojewish($jdDate);
list($hebrewMonth, $hebrewDay, $hebrewYear) = split('/',$hebrewDate);
?>
<?php
$table_name = "candle_number";
$data = $wpdb->get_results( "SELECT email FROM `{$table_name}` WHERE `datehebrew` LIKE '%%$hebrewDay%%' AND `datehebrew` LIKE '%%$hebrewMonth%%' AND date_pref = \"hebrew\"");
foreach( $data as $rs ){
echo "
<p>{$rs->email}</p>
";hat I can
$i++;
}
?>
And what I was initially thinking was to use a foreach loop with the CURL Mailchimp API to send each email to my endpoint, kind of a one off.
BUT - I know that the foreach might not loop process and it's not very clean. I think the BETTER solution would be to have every result put into an array then send THAT array in the curl, because the MC API will accept it.
I am still kind of a novice though so this is where I am stuck. So how can I take those results from my query and put them into one string?

Answer 1

Try:
//create blank array
$final_output = array();
foreach( $data as $rs ){
//add data to array in next index.
final_output[] = $rs->email;
$i++;
}
//at this point send your data array wherever you want.
print_r($final_output);
If you want to convert your data to string use:
echo json_encode($final_output);
