我有一个未序列化的数组喜欢这个
Array (
[status] => 1
[msg] => Transaction Fetched Successfully
[transaction_details] => Array (
[100002982] => Array (
[mihpayid] => 4149968
[request_id] => 635788
[bank_ref_num] => NINETE.31845.28052012
[amt] => 3295.00
[disc] => 0.00
[mode] => CC
[retries] => 0
[status] => success
[unmappedstatus] => captured
)
)
)
我想解析这个数组 这样我就可以获得状态的值，即成功
我怎么能做到这一点
$success = $array['transaction_details']['100002982']['status'];
$arr['transaction_details']['100002982']['status']
PHP 文档有一个用户注释，它建议了一种解析print_r输出的方法（类似于上面）。可以在这里找到：http://www.php.net/manual/en/function.print-r.php#93529
以下是在上述链接中找到的源代码副本：
<?php
function print_r_reverse($in) {
$lines = explode("'n", trim($in));
if (trim($lines[0]) != 'Array') {
// bottomed out to something that isn't an array
return $in;
} else {
// this is an array, lets parse it
if (preg_match("/('s{5,})'(/", $lines[1], $match)) {
// this is a tested array/recursive call to this function
// take a set of spaces off the beginning
$spaces = $match[1];
$spaces_length = strlen($spaces);
$lines_total = count($lines);
for ($i = 0; $i < $lines_total; $i++) {
if (substr($lines[$i], 0, $spaces_length) == $spaces) {
$lines[$i] = substr($lines[$i], $spaces_length);
}
}
}
array_shift($lines); // Array
array_shift($lines); // (
array_pop($lines); // )
$in = implode("'n", $lines);
// make sure we only match stuff with 4 preceding spaces (stuff for this array and not a nested one)
preg_match_all("/^'s{4}'[(.+?)'] '='> /m", $in, $matches, PREG_OFFSET_CAPTURE | PREG_SET_ORDER);
$pos = array();
$previous_key = '';
$in_length = strlen($in);
// store the following in $pos:
// array with key = key of the parsed array's item
// value = array(start position in $in, $end position in $in)
foreach ($matches as $match) {
$key = $match[1][0];
$start = $match[0][1] + strlen($match[0][0]);
$pos[$key] = array($start, $in_length);
if ($previous_key != '') $pos[$previous_key][1] = $match[0][1] - 1;
$previous_key = $key;
}
$ret = array();
foreach ($pos as $key => $where) {
// recursively see if the parsed out value is an array too
$ret[$key] = print_r_reverse(substr($in, $where[0], $where[1] - $where[0]));
}
return $ret;
}
}
?>
我还没有测试过上述功能。
