hw_getremotechildren

Name

hw_getremotechildren — Returns a remote document ID or an array of object records.

Synopsis

mixed hw_getremotechildren(hw_link, object_rec); resource hw_link: Connection ID to Hyperwave server string object_rec: Object record of a remote object

Returns

Document ID or indexed array of object records; FALSE on error

Description

This function is used to locate the children (if any) of a remote object. object_rec is the object record of the remote document whose children you want to find. If only one child object is found, its document ID is returned as an integer. If multiple objects are found, an indexed array of their object records is returned, which you might (for example) feed back into hw_getremotechildren() to drill further down into the remote document hierarchy.

Version

PHP 3 since 3.0.3, PHP 4

Example

Example 500. Find the children of a remote document

if (($children = hw_getremotechildren($hw_link, $objrec)) === FALSE) {
    echo "Could not get remote children; reason: " . hw_errormsg($hw_link) . "\n";
} else {
    if (is_array($children)) {
        echo "The remote document has the following children: \n";
        print_r($children);
    } else {
        echo "The remote document has only one child, with object ID '$children'\n";
    }
}
