What is the main issue the user is facing with generating XML for jqgrid using PHP?

The main issue the user is facing is properly generating XML for jqgrid using PHP. One way to solve this is by creating an XML string in PHP that follows the jqgrid XML format, including the necessary elements like rows, cell, and userdata. This XML string can then be echoed out to be used by jqgrid.

// Create an XML string for jqgrid
$xml = '<?xml version="1.0" encoding="utf-8"?><rows>';

// Loop through your data and add rows and cells
foreach ($data as $row) {
    $xml .= '<row id="' . $row['id'] . '">';
    $xml .= '<cell><![CDATA[' . $row['cell1'] . ']]></cell>';
    $xml .= '<cell><![CDATA[' . $row['cell2'] . ']]></cell>';
    // Add more cells as needed
    $xml .= '</row>';
}

// Add userdata if needed
$xml .= '<userdata name="total_rows">' . count($data) . '</userdata>';

$xml .= '</rows>';

// Echo out the XML string
echo $xml;
