Also "memory_limit" directive in php.ini is ignored. Reproduce code: --------------- <?php // XML Contents $sXML = <<< EOD <?xml version="1.0" encoding="UTF-8"?> <root>root node</root> EOD; $domXML = new DOMDocument(); $domXML->loadXML($sXML); // XSL Contents $sXSL = <<< EOD <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:php="http://php.net/xsl";> <xsl:template match="/"> <xsl:variable name="variable"> text </xsl:variable> <xsl:value-of select="php:functionString('trim', \$variable)" /> </xsl:template> </xsl:stylesheet> EOD; $domXSL = new DOMDocument(); $domXSL->loadXML($sXSL); // XSLT Processor $xsltProcessor = new XSLTProcessor(); $xsltProcessor->registerPHPFunctions(); $xsltProcessor->importStyleSheet($domXSL); while (true) { $xsltProcessor->transformToDoc($domXML); } Expected result: ---------------- Nothing. Actual result: -------------- All server available memory is used. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44891&edit=1
