Req #76611 [Com]: Printing DOMNode shows fake "(object value omitted)" strings

Edit report at https://bugs.php.net/bug.php?id=76611&edit=1 ID: 76611 Comment by: naitsirch at e dot mail dot de Reported by: chealer at gmail dot com Summary: Printing DOMNode shows fake "(object value omitted)" strings Status: Open Type: Feature/Change Request Package: DOM XML related PHP Version: 7.2.7 Block user comment: N Private report: N New Comment: Yes, this is verbose, but otherwise it is hard to debug code that uses those objects. People who debug with print_r/var_dump can select concrete properties/attributes of the objects to get less output. Please merge the patch. Previous Comments: ------------------------------------------------------------------------ [2018-07-21 13:21:39] cmb@php.net Changing this behavior would be as simple as applying this patch[1], but I'm not sure that would be an improvement since the output would be extremly verbose[2].

For example, the following shows that print_r() presents the lastChild property as a string "(object value omitted)", but also that this property is in fact a DOMElement object when directly printed. This affects Xdebug and makes it painful to debug the DOM extension. https://3v4l.org/NFpRS shows that this persists in 7.3.0 alpha 1. Test script: --------------- <?php $dom = new DOMDocument(); $dom->loadHTML('<h1>Configuration</h1>', LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD); print_r($dom); print_r($dom->lastChild); Actual result: -------------- DOMDocument Object ( [doctype] => [implementation] => (object value omitted) [documentElement] => (object value omitted) [actualEncoding] => [encoding] => [xmlEncoding] => [standalone] => 1 [xmlStandalone] => 1 [version] => [xmlVersion] => [strictErrorChecking] => 1 [documentURI] => [config] => [formatOutput] => [validateOnParse] => [resolveExternals] => [preserveWhiteSpace] => 1 [recover] => [substituteEntities] => [nodeName] => #document [nodeValue] => [nodeType] => 13 [parentNode] => [childNodes] => (object value omitted) [firstChild] => (object value omitted) [lastChild] => (object value omitted) [previousSibling] => [attributes] => [ownerDocument] => [namespaceURI] => [prefix] => [localName] => [baseURI] => [textContent] => Configuration ) DOMElement Object ( [tagName] => h1 [schemaTypeInfo] => [nodeName] => h1 [nodeValue] => Configuration [nodeType] => 1 [parentNode] => (object value omitted) [childNodes] => (object value omitted) [firstChild] => (object value omitted) [lastChild] => (object value omitted) [previousSibling] => [attributes] => (object value omitted) [ownerDocument] => (object value omitted) [namespaceURI] => [prefix] => [localName] => h1 [baseURI] => [textContent] => Configuration ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76611&edit=1
