($prefix? $prefix. $options ['namespaceSeparator']:'). $attributeName; $attributesArray [$attributeKey] = (string) $attribute;}} / / get child nodes from all namespaces $tagsArray = array (); foreach ($namespaces as $prefix = > $namespace) {foreach ($xml- > children ($namespace) as $childXml) {/ / recurse into child nodes $childArray = xmlToArray ($childXml, $options); list ($childTagName, $childProperties) = each ($childArray) / / replace characters in tag name if ($options ['keySearch']) $childTagName = str_replace ($options [' keySearch'], $options ['keyReplace'], $childTagName); / / add namespace prefix, if any if ($prefix) $childTagName = $prefix. $options ['namespaceSeparator']. $childTagName; if (! isset ($tagsArray [$childTagName]) {/ / only entry with this key / / test if tags of this type should always be arrays, no matter the element count $tagsArray [$childTagName] = in_array ($childTagName, $options ['alwaysArray']) | |! $options [' autoArray']? Array ($childProperties): $childProperties;} elseif (is_array ($tagsArray [$childTagName]) & & array_keys ($tagsArray [$childTagName]) = range (0, count ($tagsArray [$childTagName])-1) {/ / key already exists and is integer indexed array $tagsArray [$childTagName] [] = $childProperties } else {/ / key exists so convert to integer indexed array with previous value in position 0$ tagsArray [$childTagName] = array ($tagsArray [$childTagName], $childProperties);} / / get text content of node $textContentArray = array (); $plainText = trim ((string) $xml); if ($plainText! = =') $textContentArray [$options ['textContent']] = $plainText / / stick it all together $propertiesArray =! $options ['autoText'] | | $attributesArray | | $tagsArray | | ($plainText = ='')?
