從另一個數組中搜索字符串數組php

我有一個問題，我有兩個txt文件，其中一個包含要搜索的值，其次包含從哪裏找到包含信息的文本行的信息從第一個txt文件。 1. txt文件看起來像這樣：從另一個數組中搜索字符串數組php

txt文件看起來像這樣：

<?xml version="1.0" encoding="UTF-8"?> 
 
<osm version="0.6" generator="CGImap 0.4.3 (797 thorn-02.openstreetmap.org)" copyright="OpenStreetMap and contributors" attribution="http://www.openstreetmap.org/copyright" license="http://opendatacommons.org/licenses/odbl/1-0/"> 
 
<bounds minlat="56.7042000" minlon="21.5789000" maxlat="56.7340000" maxlon="21.6328000"/>

<node id="29012516" visible="true" version="2" changeset="3100827" timestamp="2009-11-12T19:23:00Z" user="Abuls" uid="14113" lat="56.7180402" lon="21.6222515"/> 
 
<node id="29012514" visible="true" version="2" changeset="3100827" timestamp="2009-11-12T19:23:00Z" user="Abuls" uid="14113" lat="56.7191410" lon="21.6324709"/>

所以我需要找到在2.txt所有的行，其中nod id等於1. txt文件中給出的nummber，並且我需要刪除搜索到的字符串行的緯度和經度值。

任何人都可以幫助我嗎？

也就是說，我已經嘗試了這麼多的代碼選項，我無法理解的事情我在做什麼了 - 所有的東西我迄今發現的是，如果其他數組包含您正在搜索的完全相同的值，則不會有問題來比較數組。但在這種情況下，我正在搜索數組值部分包含我正在搜索的值的情況 –

因此基本上，如果在2.txt的節點ID中找到來自1.txt的任何行，則檢索相應的緯度和經度值。對？ –

是的，這是正確的 –

嘗試這樣的事情。

$handle = fopen("1.txt", "r"); 

$xml = simplexml_load_file("2.xml") or die("Error: Cannot create object"); 

if ($handle) { 

    while (($line = fgets($handle)) !== false) { 

     foreach ($xml as $key => $value) { 

      if ($value['id'] == trim($line)) { 

       echo "id: " . $value['id'] . " Lat => " . $value['lat'] . " " . "lon => " . $value['lon'] . "</br>"; 
      } 
     } 
    } 

    fclose($handle); 

} else { 
    // error opening the file. 
}

輸出

id: 29012520 Lat => 56.7183050 lon => 21.6051939 
id: 29012516 Lat => 56.7180402 lon => 21.6222515 
id: 29012514 Lat => 56.7191410 lon => 21.6324709

非常感謝！這工作正常 –

不客氣。 :) –

我會給你一些小小的代碼讓你開始。

// Step 1: Need to load the files: 
// put the paths to your files in these two variables 
$textFile = 'locations.txt'; 
$xmlFilePath = 'data.xml'; 

$idHandle = fopen($textFile, 'r'); 
$dom = new DOMDocument(); 
$dom->load($xmlFilePath); 
$dom->preserveWhiteSpace = false; 

$xpath = new DOMXPath($dom); 

// Step 2: getting each line in the text file 
while ($id = fgets($idHandle)) { 
    $id = (int) $id; 
    // Step 3: selecting all the nodes that have ids matching 
    // the id in the text file 
    $query = "//node[@id={$id}]"; 
    $list = $xpath->evaluate($query); 

    foreach ($list as $node) { 
    echo "Node: {$id}, Latitude: " . $node->getAttribute('lat') 
     . ", " . "Longitude: " . $node->getAttribute('lon') . "\n"; 
    } 
}

我得到以下輸出：

Node: 29012520, Latitude: 56.7183050, Longitude: 21.6051939 
Node: 29012516, Latitude: 56.7180402, Longitude: 21.6222515 
Node: 29012514, Latitude: 56.7191410, Longitude: 21.6324709

讓我知道你需要什麼。

您可以結合使用SimpleXMLElement,foreach,file_get_contents和preg_split來獲得您想要的結果。這是什麼意思：

<?php 
     // GET THE CONTENTS OF THE TEXT FILE CONTAINING IDS 
     // AND BUNDLE IT INTO A VARIABLE FOR LATER USE. 
     $txtFileContent = file_get_contents(__DIR__ . "/ids.txt"); 

     // CONVERT THE CONTENTS OF THE TEXT FILE TO AN ARRAY 
     $arrTextData = preg_split("#[\n\r]#", $txtFileContent); 


     // CREATE A SIMPLE XML ELEMENT USING THE XML FILE. 
     $sXML   = new SimpleXMLElement(__DIR__ . "/xml_file_name.xml", 0, true); 

     // LOOP THROUGH ALL THE ELEMENTS IN THE CHILDREN LIST 
     // AND TRY TO MATCH EACH ELEMENT WITH EACH KEY ON THE $arrTextData ARRAY. 
     // THIS WOULD IMPLY A NESTED LOOP... ALSO BUILD AN ARRAY OF 
     // MATCHED-ELEMENTS WITH THE UNIQUE ID AS THE KEY IN THE PROCESS. 
     $arrMatchedElements = array(); 

     foreach($sXML->children() as $nodeKey=>$nodeData){ 
      /**@var SimpleXMLElement $nodeData */ 
      foreach($arrTextData as $iKey=>$ID){ 
       if($ID == $nodeData->attributes()->id){ 
        $arrMatchedElements[$ID] = $nodeData->attributes(); 
       } 
      } 
     } 

     var_dump($arrMatchedElements); 
     // THE var_dump(...) PRODUCES...    
     array (size=3) 
      29012520 => 
      object(SimpleXMLElement)[6] 
       public '@attributes' => 
       array (size=9) 
        'id' => string '29012520' (length=8) 
        'visible' => string 'true' (length=4) 
        'version' => string '2' (length=1) 
        'changeset' => string '3098893' (length=7) 
        'timestamp' => string '2009-11-12T15:12:59Z' (length=20) 
        'user' => string 'Abuls' (length=5) 
        'uid' => string '14113' (length=5) 
        'lat' => string '56.7183050' (length=10) 
        'lon' => string '21.6051939' (length=10) 
      29012516 => 
      object(SimpleXMLElement)[5] 
       public '@attributes' => 
       array (size=9) 
        'id' => string '29012516' (length=8) 
        'visible' => string 'true' (length=4) 
        'version' => string '2' (length=1) 
        'changeset' => string '3100827' (length=7) 
        'timestamp' => string '2009-11-12T19:23:00Z' (length=20) 
        'user' => string 'Abuls' (length=5) 
        'uid' => string '14113' (length=5) 
        'lat' => string '56.7180402' (length=10) 
        'lon' => string '21.6222515' (length=10) 
      29012514 => 
      object(SimpleXMLElement)[8] 
       public '@attributes' => 
       array (size=9) 
        'id' => string '29012514' (length=8) 
        'visible' => string 'true' (length=4) 
        'version' => string '2' (length=1) 
        'changeset' => string '3100827' (length=7) 
        'timestamp' => string '2009-11-12T19:23:00Z' (length=20) 
        'user' => string 'Abuls' (length=5) 
        'uid' => string '14113' (length=5) 
        'lat' => string '56.7191410' (length=10) 
        'lon' => string '21.6324709' (length=10)

您也可以使這更面向對象，像這樣：

<?php 
     // GET THE CONTENTS OF THE TEXT FILE CONTAINING IDS 
     // AND BUNDLE IT INTO A VARIABLE FOR LATER USE. 
     $txtFileContent = file_get_contents(__DIR__ . "/ids.txt"); 

     // CONVERT THE CONTENTS OF THE TEXT-FILE TO AN ARRAY 
     $arrTextData = preg_split("#[\n\r]#", $txtFileContent); 

     // CREATE A SIMPLE XML ELEMENT USING THE XML FILE. 
     $sXML   = new SimpleXMLElement(__DIR__ . "/xml_file_name.xml", 0, true); 

     // LOOP THROUGH ALL THE ELEMENTS IN THE CHILDREN LIST 
     // AND TRY TO MATCH EACH ELEMENT WITH EACH KEY ON THE $arrTextData ARRAY. 
     // THIS WOULD IMPLY A NESTED LOOP... ALSO BUILD A MATCHED-ELEMENTS 
     // ARRAY IN THE PROCESS. 
     $arrMatchedElements = array(); 

     foreach($sXML->children() as $nodeKey=>$nodeData){ 
      /**@var SimpleXMLElement $nodeData */ 
      foreach($arrTextData as $iKey=>$ID){ 
       if($ID == $nodeData->attributes()->id){ 
        $tempPropsObj    = new stdClass(); 
        $tempPropsObj->id   = $nodeData->attributes() 
          ->id->__toString(); 
        $tempPropsObj->lon   = $nodeData->attributes()->lon->__toString(); 
        $tempPropsObj->lat   = $nodeData->attributes()->lon->__toString(); 
        $tempPropsObj->uid   = $nodeData->attributes()->uid->__toString(); 
        $tempPropsObj->user   = $nodeData->attributes()->user->__toString(); 
        $tempPropsObj->timestamp = $nodeData->attributes()->timestamp->__toString(); 
        $tempPropsObj->changeset = $nodeData->attributes()->changeset->__toString(); 
        $tempPropsObj->version  = $nodeData->attributes()->version->__toString(); 
        $tempPropsObj->visible  = $nodeData->attributes()->visible->__toString(); 
        $arrMatchedElements[$ID] = $tempPropsObj; 
       } 
      } 
     } 

     var_dump($arrMatchedElements); 
     // DISPLAYS... 
     array (size=3) 
      29012520 => 
      object(stdClass)[6] 
       public 'id' => string '29012520' (length=8) 
       public 'lon' => string '21.6051939' (length=10)

       public 'timestamp' => string '2009-11-12T15:12:59Z' (length=20) 
       public 'changeset' => string '3098893' (length=7) 
       public 'version' => string '2' (length=1) 
       public 'visible' => string 'true' (length=4) 
      29012516 => 
      object(stdClass)[5]

      29012514 => 
      object(stdClass)[8] 
       public 'id' => string '29012514' (length=8) 
       public 'lon' => string '21.6324709' (length=10)

希望這有助於有點.... GOOD LUCK ;-)

好首先在你的例子中你的XML代碼沒有結尾標籤</osm>，這在複製粘貼時可能只是一個錯誤。

因爲你有一個XML文件，你不需要自己解析它，PHP提供了很多功能爲你做。

據我所知，不可能檢查一個XML的值是否等於另一個值，所以你必須在兩個循環中檢查它，正如你可以在下面的例子中看到的。

<?php 
//Read the id's 
$ids = file("txt.txt", FILE_IGNORE_NEW_LINES); 

//Read the XML file 
$xmlContent = file_get_contents("txt.xml"); 

//Convert XML file to an object 
$xmlObjects = simplexml_load_string($xmlContent); 

foreach ($ids as $id) { 
    foreach ($xmlObjects->node as $node) { 

     //Check if id's are equal 
     if ($node["id"] == $id) { 
      echo "ID: ".$id; 
      echo " Latitude: ".$node["lat"]; 
      echo " Longidtude ".$node["lon"]; 
      echo "<br>"; 
     } 
    } 
}

輸出：

ID: 29012520 Latitude: 56.7183050 Longidtude 21.6051939 
ID: 29012516 Latitude: 56.7180402 Longidtude 21.6222515 
ID: 29012514 Latitude: 56.7191410 Longidtude 21.6324709
