我正在使用zapier自动记住牛奶任务，如果原子饲料发生任何变化，它会触发。问题是zapier使用php://input
<?php
$xhtml = file_get_contents('php://input');
?>
原始数据如下所示：
@class: rtm_due
span: [{'#text': 'Due:', '@class': 'rtm_due_title'}, {'#text': 'Sat 16 Jul 16', '@class': 'rtm_due_value'}]
@class: rtm_priority
span: [{'#text': 'Priority:', '@class': 'rtm_priority_title'}, {'#text': '1', '@class': 'rtm_priority_value'}]
@class: rtm_tags
span: [{'#text': 'Tags:', '@class': 'rtm_tags_title'}, {'#text': 'gcal-work, github', '@class': 'rtm_tags_value'}]
@class: rtm_location
span: [{'#text': 'Location:', '@class': 'rtm_location_title'}, {'#text': 'none', '@class': 'rtm_location_value'}]
@class: rtm_list
span: [{'#text': 'List:', '@class': 'rtm_list_title'}, {'#text': 'Work', '@class': 'rtm_list_value'}]
假设我想在@class：rtm_due下提取截止日期星期六16 7月16日;我怎样才能提取这个？正则表达式（preg_match）会有任何帮助吗？如果是这样的话？

也许你可能想要在一个扭曲的＆amp;复杂的方式（即在使用Regex和Looping构造的函数中获取所需的数据）。请考虑以下功能。值得注意的是，虽然它可能看起来扭曲和令人费解，您不仅限于获取日期值。这意味着您还可以访问该文件中的所有键值对：如果您需要在某个时刻......
<?php
$file = __DIR__ . "/file.txt"; //<== THE NAME OF THE FILE CONTAINING YOUR DATA
/*************** BEGIN FUNCTIONS ***************/
function parseFile($file){
$arrFileContent = [];
// IF THE FILE DOES NOT EXIST RETURN NULL
if(!file_exists($file)){
return null;
}
// GET THE DATA FROM THE FILE & STORE IT IN A VARIABLE
$strFileDataContent = file_get_contents($file);
// IF THE FILE CONTAINS NOTHING RETURN NULL AS WELL
if(empty($strFileDataContent)){
return null;
}
// SPLIT THE CONTENTS OF THE FILE (STRING) AT THE END OF EACH LINE
// THUS CREATING AN ARRAY OF LINES OF TEXT-DATA
$arrFileDataLines = explode("\n", $strFileDataContent);
// LOOP THROUGH THE ARRAY PRODUCED ABOVE & PERFORM SOME PATTERN MATCHING
// AND TEXT EXTRACTION WITHIN THE LOOP
foreach($arrFileDataLines as $iKey=>$lineData){
$arrSubLines = explode("\n", $lineData);
foreach($arrSubLines as $intKey=>$strKeyInfo){
$rxClass = "#(^@class:)(\s*)(.*$)#i";
$rxSpan = "#(^span:)(\s*)?(.+$)#si";
preg_match($rxClass, $strKeyInfo, $matches);
preg_match($rxSpan, $strKeyInfo, $matches2);
if($matches) {
list(, $key, $null, $val) = $matches;
$keyA = str_replace("rtm_", "", $val);
if (!array_key_exists($keyA, $arrFileContent)) {
$arrFileContent[$keyA] = $val;
}
}
if($matches2) {
list(, $key2, $null, $val2) = $matches2;
$keyB = $keyA ."Data";
if (!array_key_exists($keyB, $arrFileContent)) {
$arrFileContent[$keyB] = parseSpanValues($val2, str_replace("rtm_", "", $keyA));
}
}
}
}
return $arrFileContent;
}
function parseSpanValues($spanData, $prefix){
$arrSpanData = explode(", ", preg_replace("#[\{\}\[\]\"\'\#\@]#", "", $spanData));
$objSpanData = new stdClass();
$cleanVal = "";
if($prefix == "tags"){
$cnt = 0;
foreach($arrSpanData as $i=>$val){
if(!stristr($val, ":")){
$cleanVal .= ", " . $val ;
$cnt++;
}
}
$arrSpanData[2] = $arrSpanData[2] . $cleanVal;
array_splice($arrSpanData, 3, $cnt);
}
foreach($arrSpanData as $iKey=>&$spanVal){
$arrSplit = preg_split("#\:\s#", $cleanVal . $spanVal);
$key = "text";
if($iKey == 0){
$key = "{$prefix}Text";
}else if($iKey == 1){
$key = "{$prefix}TextClass";
}else if($iKey == 2){
$key = "{$prefix}Value";
}else if($iKey == 3){
$key = "{$prefix}ValueClass";
}
if(isset($arrSplit[1])){
$objSpanData->$key = $arrSplit[1];
}
}
return $objSpanData;
}
/*************** END OF FUNCTIONS ***************/
var_dump(parseFile($file));
// PRODUCES SOMETHING LIKE:
array (size=10)
'due' => string 'rtm_due' (length=7)
'dueData' =>
object(stdClass)[1]
public 'dueText' => string 'Due' (length=3)
public 'dueTextClass' => string 'rtm_due_title' (length=13)
public 'dueValue' => string 'Sat 16 Jul 16' (length=13)
public 'dueValueClass' => string 'rtm_due_value' (length=13)
'priority' => string 'rtm_priority' (length=12)
'priorityData' =>
object(stdClass)[2]
public 'priorityText' => string 'Priority' (length=8)
public 'priorityTextClass' => string 'rtm_priority_title' (length=18)
public 'priorityValue' => string '1' (length=1)
public 'priorityValueClass' => string 'rtm_priority_value' (length=18)
'tags' => string 'rtm_tags' (length=8)
'tagsData' =>
object(stdClass)[3]
public 'tagsText' => string 'Tags' (length=4)
public 'tagsTextClass' => string 'rtm_tags_title' (length=14)
public 'tagsValue' => string 'gcal-work, github, stack-overflow' (length=33)
public 'text' => string 'rtm_tags_value' (length=14)
'location' => string 'rtm_location' (length=12)
'locationData' =>
object(stdClass)[4]
public 'locationText' => string 'Location' (length=8)
public 'locationTextClass' => string 'rtm_location_title' (length=18)
public 'locationValue' => string 'none' (length=4)
public 'locationValueClass' => string 'rtm_location_value' (length=18)
'list' => string 'rtm_list' (length=8)
'listData' =>
object(stdClass)[5]
public 'listText' => string 'List' (length=4)
public 'listTextClass' => string 'rtm_list_title' (length=14)
public 'listValue' => string 'Work' (length=4)
public 'listValueClass' => string 'rtm_list_value' (length=14)
就像现在一样，如果你想在数组[Element dueData ]中获取第一个实例的日期，你可以简单地做这样的事情：
<? php
$data = parseFile($file);
$dateDateValue = $data['dueData']->dueValue;
var_dump($dateDateValue); // PRODUCES:: 'Sat 16 Jul 16'
希望这种尝试（根本没有）给你一个关于如何自己即兴创作的模糊概念。
干杯＆amp;祝你好运!!!

我认为这个正则表达式会起作用：
@class:\s*rtm_due\nspan:\s*\[{.*}, {'#text':\s*(.*),\s*'@class':\s*'rtm_due_value'}]
演示here
但仅适用于due date
如果您需要location，则需要将正则表达式添加到：
@class:\s*rtm_location\nspan:\s*\[{.*}, {'#text':(.*),\s*'@class':\s*'rtm_location_value'}]
组1应该给出所需的值。
这是我在网上提供的php正则表达式测试人员one中得到的输出：
[0] => @class: rtm_due
span: [{'#text': 'Due:', '@class': 'rtm_due_title'}, {'#text': 'Sat 16 Jul 16', '@class': 'rtm_due_value'}]
[1] => 'Sat 16 Jul 16'
