<?php $content = <<<XML <?xml version= "1.0" encoding= "UTF-8" ?> <test> <global_setting> <ping_protocol>HTTP</ping_protocol> <ping_port>80</ping_port> <ping_path>/index.html</ping_path> <response_timeout>5000</response_timeout> <health_check_interval>3000</health_check_interval> <unhealthy_threshold>2</unhealthy_threshold> <healthy_threshold>3</healthy_threshold> </global_setting> <instances> <instance ip= "192.168.234.121" /> <instance ip= "192.168.234.28" /> </instances> </test> XML; $test = new SimpleXMLElement( $content ); //获得ping_protocol的值 $ping_protocol = $test ->global_setting->ping_protocol; echo "ping_protocol : $ping_protocol \n" ; //打印出所有instance的IP foreach ( $test ->instances->instance as $instance ) { echo "IP: {$instance['ip']} \n" ; } //这里经过测试,发现使用var_dump之类的似乎不能有效输出值,用echo比较顺利, //还有就是上面的那个xml的例子可以去掉<?xml version="1.0" encoding="UTF-8"?> //也可以去掉头尾///的<<<xml,然后当做普通字符串那样对待,但是没有测试中文等 |
希望本文所述对大家PHP程序设计有所帮助。
