我无法理解使用 SimpleXMLElement 打印数组结果的正确语法。从我的 xml 结果中,我必须要求用户将自己与数组中找到的一个人匹配,并且不确定执行此操作的最佳方法是什么。
示例 XML 结果:
[authentication] => SimpleXMLElement Object
(
[age] => SimpleXMLElement Object
(
[code] => 5
[ambiguous] => SimpleXMLElement Object
(
[person] => Array
(
[0] => SimpleXMLElement Object
(
[name] => Paul Foreman
[question] => SimpleXMLElement Object
(
[id] => dcalc3
[prompt] => What+do+the+%3Cb%3Elast+four%3C%2Fb%3E+digits+of+your+Social+Security+Number+add+up+to%3F
[answer] => 5
)
)
[1] => SimpleXMLElement Object
(
[name] => Paul Foreman
[question] => SimpleXMLElement Object
(
[id] => dcalc3
[prompt] => What+do+the+%3Cb%3Elast+four%3C%2Fb%3E+digits+of+your+Social+Security+Number+add+up+to%3F
[answer] => 6
)
)
)
)
)
)
我正在寻找的解决方案:
<?php
$string = $xml_result;
$xml = new SimpleXMLElement($string);
$is_age_code = $xml->authentication->{'age'}->code;
if($x_is_age_code == '5'){
// code 5 means more than one match found
// Ask user verification question
// If answer matches question
// Set current user as that person
}
?>
我如何找出数组中有多少“人”并用数字标识它们?
