这篇文章主要介绍了PHP生成plist数据的方法,可实现PHP数组转换为苹果plist XML或文本格式的功能,需要的朋友可以参考下

本文实例讲述了PHP生成plist数据的方法。分享给大家供大家参考。具体如下:

这段代码实现PHP数组转换为苹果plist XML或文本格式

*/ function plist_encode_text ($obj) { $plist = new PropertyList($obj); return $plist->text(); } function plist_encode_xml ($obj) { $plist = new PropertyList($obj); return $plist->xml(); } class PropertyList { private $obj, $xml, $text; public function __construct ($obj) { $this->obj = $obj; } private static function is_assoc ($array) { return (is_array($array) && 0 !== count(array_diff_key($array, array_keys(array_keys($array))))); } public function xml () { if (isset($this->xml)) return $this->xml; $x = new XMLWriter(); $x->openMemory(); $x->setIndent(TRUE); $x->startDocument('1.0', 'UTF-8'); $x->writeDTD('plist', '-//Apple//DTD PLIST 1.0//EN', 'http://www.apple.com/DTDs/PropertyList-1.0.dtd'); $x->startElement('plist'); $x->writeAttribute('version', '1.0'); $this->xmlWriteValue($x, $this->obj); $x->endElement(); // plist $x->endDocument(); $this->xml = $x->outputMemory(); return $this->xml; } public function text() { if (isset($this->text)) return $this->text; $text = ''; $this->textWriteValue($text, $this->obj); $this->text = $text; return $this->text; } private function xmlWriteDict(XMLWriter $x, &$dict) { $x->startElement('dict'); foreach($dict as $k => &$v) { $x->writeElement('key', $k); $this->xmlWriteValue($x, $v); } $x->endElement(); // dict } private function xmlWriteArray(XMLWriter $x, &$arr) { $x->startElement('array'); foreach($arr as &$v) $this->xmlWriteValue($x, $v); $x->endElement(); // array } private function xmlWriteValue(XMLWriter $x, &$v) { if (is_int($v) || is_long($v)) $x->writeElement('integer', $v); elseif (is_float($v) || is_real($v) || is_double($v)) $x->writeElement('real', $v); elseif (is_string($v)) $x->writeElement('string', $v); elseif (is_bool($v)) $x->writeElement($v?'true':'false'); elseif (PropertyList::is_assoc($v)) $this->xmlWriteDict($x, $v); elseif (is_array($v)) $this->xmlWriteArray($x, $v); elseif (is_a($v, 'PlistData')) $x->writeElement('data', $v->base64EncodedData()); elseif (is_a($v, 'PlistDate')) $x->writeElement('date', $v->encodedDate()); else { trigger_error("Unsupported data type in plist ($v)", E_USER_WARNING); $x->writeElement('string', $v); } } private function textWriteValue(&$text, &$v, $indentLevel = 0) { if (is_int($v) || is_long($v)) $text .= sprintf("%d", $v); elseif (is_float($v) || is_real($v) || is_double($v)) $text .= sprintf("%g", $v); elseif (is_string($v)) $this->textWriteString($text, $v); elseif (is_bool($v)) $text .= $v?'YES':'NO'; elseif (PropertyList::is_assoc($v)) $this->textWriteDict($text, $v, $indentLevel); elseif (is_array($v)) $this->textWriteArray($text, $v, $indentLevel); elseif (is_a($v, 'PlistData')) $text .= 'hexEncodedData() .
