Encoding JSON with double quotes instead of single quotes - php

Question

I have a json.php file which delivers results like this:
{ "markers": [ {'a1_id':"4213CK58", etc.
The problem is that the Google Maps API doesn't like single quotes and so I need my results like this:
{ "markers": [ {"a1_id":"4213CK58", etc.
Replacing ' by " in the code doesn't deliver...
<?php
// Iterate over the rows
$nextRow= $result->nextRow();
$r = 1;
$info = array();
while ( $nextRow ) {
$nextColumn = $result->nextColumn();
// Has this column been printed already
if ( $unique )
{
$d = $result->getDataForField($unique);
if ( array_key_exists($d, $already) )
{
$nextRow= $result->nextRow();
continue;
}
$already[$d] = true;
}
echo '{';
// Iterate over the columns in each row
while ( $nextColumn )
{
// Get the variable
$variable = $result->getOutputVariable();
$name = $variable->getName(true);
$data = $result->getDataForField();
if ( !isset($info[$name]) ) {
$info[$name]['translate'] = $variable->shouldTranslate();
$info[$name]['type'] = $variable->getDataType();
$info[$name]['linkable'] = $variable->isLinkable();
}
// Translate the data if requested
if ( $info[$name]['translate'] ) {
$data = LQMTemplate::_($data);
}
$data = $variable->format($data, false);
$type = $info[$name]['type'];
if ( ($type == 'bool') or ($type == 'boolean') )
{
$data = $data ? '1' : '0';
echo "'$name':$data";
} elseif ( $encode ) {
// Can we use json_encode ?
// str_replace because some versions of PHP have a bug that will over escape forward slashes
echo "'$name':".str_replace('\\/', '/', json_encode($data));
} else {
$data = LQMUtility::jsonEscape($data, '"');
echo "'$name':\"$data\"";
}
// Conditionally print the next column
$nextColumn = $result->nextColumn();
if ( $nextColumn ) echo ",\n ";
}
// Conditionally print the next column
$nextRow = $result->nextRow();
echo $nextRow ? "},\n" : "}\n";
$r++;
}
unset($result);
echo ']}';
}
}

Create an array containing the data you want to encode and then use PHP's builtin json_encode() function.
