本篇文章是对array2xml和xml2array以及xml与array的互相转化进行了详细的分析介绍,需要的朋友参考下
php在做后台服务器的时候,经常会遇到这种情况,需要解析来自前台的xml文件,并将数据以xml格式返回,在这种情况下,xml与php中关联数组的转化是非常频繁的事情。比如flex和其他客户端程序与服务器的交互,经常会使用这种方法。下面是我归纳的两个方法,大大简化了xml与数组相互转化的工作量。 复制代码 代码如下: /** * * 将简单数组转化为简单的xml * @param string $data 要进行转化的数组 * @param string $tag 要使用的标签 * @example * $arr = array( 'rtxAccount'=>'aaron','ipAddr'=>'192.168.0.12', 'conferenceList'=>array('conference'=> array( array('conferenceId'=>1212,'conferenceTitle'=>'quanshi 444','smeAccount'=>'//www.jb51.net'), array('conferenceId'=>454,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'//www.jb51.net'), array('conferenceId'=>6767,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'//www.jb51.net'), array('conferenceId'=>232323,'conferenceTitle'=>'quanshi uuu','smeAccount'=>'//www.jb51.net'), array('conferenceId'=>8989,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'//www.jb51.net'), array('conferenceId'=>1234343212,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'//www.jb51.net') ) ) ); 转化为: <rtxAccount>aaron</rtxAccount> <ipAddr>192.168.0.12</ipAddr> <conferenceList> <conference> <conferenceId>1212</conferenceId> <conferenceTitle>quanshi 444</conferenceTitle> <smeAccount>//www.jb51.net</smeAccount> </conference> <conference> <conferenceId>454</conferenceId> <conferenceTitle>quanshi meetting</conferenceTitle> <smeAccount>//www.jb51.net</smeAccount> </conference> <conference> <conferenceId>6767</conferenceId> <conferenceTitle>quanshi meetting</conferenceTitle> <smeAccount>//www.jb51.net</smeAccount> </conference> <conference> <conferenceId>232323</conferenceId> <conferenceTitle>quanshi uuu</conferenceTitle> <smeAccount>//www.jb51.net</smeAccount> </conference> <conference> <conferenceId>8989</conferenceId> <conferenceTitle>quanshi meetting</conferenceTitle> <smeAccount>//www.jb51.net</smeAccount> </conference> <conference> <conferenceId>1234343212</conferenceId> <conferenceTitle>quanshi meetting</conferenceTitle> <smeAccount>//www.jb51.net</smeAccount> </conference> </conferenceList> */ function array2xml($data,$tag = '') { $xml = '';
foreach($data as $key => $value) { if(is_numeric($key)) { if(is_array($value)) { $xml .= "<$tag>"; $xml .= array2xml($value); $xml .="</$tag>"; } else { $xml .= "<$tag>$value</$tag>"; } } else { if(is_array($value)) { $keys = array_keys($value); if(is_numeric($keys[0])) { $xml .=array2xml($value,$key); } else { $xml .= "<$key>"; $xml .=array2xml($value); $xml .= "</$key>"; }
} else { $xml .= "<$key>$value</$key>"; } } } return $xml; } }
xml2array 复制代码 代码如下: /** * * 将简单的xml转化成关联数组 * @param string $xmlString xml字符串 * @example * <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <RTXConferenceReqDTO> <conferenceTitle>IT交流会</conferenceTitle> <startTime>2011-12-19 12:00:00</startTime> <rtxAccount>andy1111111</rtxAccount> <ipAddr>192.168.1.56</ipAddr> <duration>120</duration> <conferenceType>1</conferenceType> <invitees> <invitee> <rtxAccount>被邀请人1的RTX账号</rtxAccount> <tel>被邀请人1电话号码</tel> </invitee> <invitee> <rtxAccount>被邀请人2的RTX账号</rtxAccount> <tel>被邀请人2电话号码</tel> </invitee> </invitees> </RTXConferenceReqDTO> 转化之后的关联数组: Array ( [conferenceTitle] => IT交流会 [startTime] => 2011-12-19 12:00:00 [rtxAccount] => andy1111111 [ipAddr] => 192.168.1.56 [duration] => 120 [conferenceType] => 1 [invitees] => Array ( [invitee] => Array ( [0] => Array ( [rtxAccount] => 被邀请人1的RTX账号 [tel] => 被邀请人1电话号码 ) [1] => Array ( [rtxAccount] => 被邀请人2的RTX账号 [tel] => 被邀请人2电话号码 ) ) ) ) */ function xml2array($xmlString = '') { $targetArray = array(); $xmlObject = simplexml_load_string($xmlString); $mixArray = (array)$xmlObject; foreach($mixArray as $key => $value) { if(is_string($value)) { $targetArray[$key] = $value; } if(is_object($value)) { $targetArray[$key] = xml2array($value->asXML()); } if(is_array($value)) { foreach($value as $zkey => $zvalue) { if(is_numeric($zkey)) { $targetArray[$key][] = xml2array($zvalue->asXML()); } if(is_string($zkey)) { $targetArray[$key][$zkey] = xml2array($zvalue->asXML()); } } } } return $targetArray;
