Ändern Sie die Zeichenfolge von Kleinbuchstaben in den ursprünglichen Fall

Hallo alle nur eine kurze Frage 'Wahrscheinlich sehr einfach', aber ich habe eine Zeichenfolge, die ich in Kleinbuchstaben umgewandelt, um nach Zeichenfolge in Datei suchen, aber jetzt muss ich die Zeichenfolge konvertieren, die es in der gefunden Datei zurück in die ursprüngliche Zeichenfolge. Das folgende ist mein CodeÄndern Sie die Zeichenfolge von Kleinbuchstaben in den ursprünglichen Fall

PHP

<?php 
     $searchfor = $_SESSION['username']; 
     $searchfor = strtolower($username); 

     // the following line prevents the browser from parsing this as HTML. 
     header('Content-Type: text/plain'); 

     // get the file contents, assuming the file to be readable (and exist) 
     $contents = file_get_contents('posts/contents.php'); 
     $contents = strtolower($contents); 
      #$posts = file_get_contents('posts/contents.php'); 
     //Convert urls to <a> links 
     $contents = preg_replace("/([\w]+\:\/\/[\w-?&;#~=\.\/\@]+[\w\/])/", "<a target=\"_blank\" class=\"external\" href=\"$1\">$1</a>", $contents); 

     //Convert hashtags to twitter searches in <a> links 
     $contents = preg_replace("/#([A-Za-z0-9\/\.]*)/", "<a target=\"_new\" href=\"javascript:myApp.alert('Hashtag\'s currently not working.');\">#$1</a>", $contents); 

     //Convert attags to twitter profiles in &lt;a&gt; links 
     $contents = preg_replace("/@([A-Za-z0-9\_\/\.]*)/", "<a href=\"profile.php?username=$1\">@$1</a>", $contents); 
     // escape special characters in the query 
     $pattern = preg_quote('@'.$searchfor, '/'); 
     // finalise the regular expression, matching the whole line 
     $pattern = "/^.*$pattern.*\$/m"; 
     // search, and store all matching occurences in $matches 
     if(preg_match_all($pattern, $contents, $matches)){ 
      $day = date("l"); 
      $time = date("h:i A"); 
      $newDateTime = date('g:i A', strtotime($time)); 
      $message = implode("\n", $matches[0]); 
      echo '<div class="card facebook-card"> 
        <div class="card-header no-border"> 
        <div class="facebook-name">iCode Mentions</div> 
        <div class="facebook-date">'.$day.' at '.$newDateTime.'</div> 
        </div> 
        <div class="card-content"> 
        <div class="card-content-inner">'.$message.'</div> 
        </div> 
       </div>'; 
     } 
     else{ 
      echo "No mentions"; 
     } 
     ?>

Jetzt bin ich wirklich gehofft, dass es einen Weg zu konvertieren ist alles zurück zu seinem ursprünglichen Gehäuse

Auf der Linie '$ contents = strtolower ($ str) geändert wurde hat,', wo kommt '$ str' kommen aus? – BeetleJuice

aktiv ????????? –

$contents = file_get_contents('posts/contents.php'); 
    $var = $chontents; //before anything happen to it 
    $contents = strtolower($str); //after changing to lowercase

Sie $ var verwenden können, da es nicht durch irgendetwas

Ahmad woher kennst du das OP wo '$ str' herkam? Das einzige Mal, wenn wir es sehen, wird sein Wert gelesen: '$ contents = strtolower ($ str);' Wir sehen nicht, worauf es eingestellt ist. – BeetleJuice

Ich denke, er bekommt es von file_get_contents ('posts/contents.php'); –

Ja, ich vergesse nur, $ str zu ändern $ Inhalte –

Ändern Sie die Zeichenfolge von Kleinbuchstaben in den ursprünglichen Fall
