Closed 8 years ago.
Referring to the title. I have an array which I coded like this:-
$query = "SELECT * FROM server";
$result = mysql_query($query);
$dServer = array();
while($row = mysql_fetch_assoc($result)) {
$dServer[] = $row['model'];
}
Now, how do I pass the $dServer array into a Javascript array?
For example, this array:
var a = new Array();

Answer 1

$query = "SELECT * FROM server";
$result = mysql_query($query);
$dServer = array();
while($row = mysql_fetch_assoc($result)){
$dServer[] = $row['model'];
}
?>
<script type="text/javascript">
var a = <?php echo json_encode($dServer); ?>;
</script>

Answer 2

Encode it as a json object.
<?
$arr = array('entry' => 'content');
?>
<script>
var data = <?=json_encode($arr);?>;
alert(data['entry']);
</script>

Answer 3

Try to get use of ajax request and json_encode.
Second variant
<?php
$query = "SELECT * FROM server";
$result = mysql_query($query);
$dServer = array();
while($row = mysql_fetch_assoc($result))
{
$dServer[] = $row['model'];
}
?>
var a = <?php echo json_encode($dServer);?>;

Answer 4

In addition to the ajax / json methods mentioned, you can directly print out the values:
<?php
$query = "SELECT * FROM server";
$result = mysql_query($query);
?>
<script type="text/javascript">
var a = new Array();
<?php
while($row = mysql_fetch_assoc($result)){
echo "a['model'] = " . $row['model'] . ";";
echo "a['nextField'] = " . $row['nextField'] . ";";
}
?>
</script>
