<br> 在下一个 foreach 项目中插入空格

【中文标题】<br> 在下一个 foreach 项目中插入空格

【英文标题】：<br> inserting space in next foreach item

【问题描述】：

我实际上是在做一个拼写检查器。我要做的是按空格将字符串拆分为单词，添加标记以忽略标点符号和nl2br() 函数以保留<br>s。现在，问题是，当我说要忽略 br 时，它会将其视为一个单词，甚至会在下一个单词中添加一个空格。下面我给你看代码……

spellchecker.php

function checkspell($string, $translate) 
    $string = $string;
    $counter = 0;
    $arr = explode(' ', punctuate($string, $translate));
    foreach($arr as $str) 
        if (substr($str, 1, 4) == "punc") 
            echo $str;
         elseif ($str == "<br>") 
            echo "<br />";
         elseif ($str == "") 
            echo "<punc> </punc>";
         else 
            $space = "yes";
            if (substr($str, -2, 2) == "<>") 
            $space = "no";
            $str = str_replace("<>", "", $str);
            
        $exists = mysql_query("SELECT COUNT(word) FROM unicode WHERE word = '$str'") or die (mysql_error());
    if (mysql_result($exists, 0) == 0) 
        $counter++;
        if ($space == "yes") 
            echo "<span class=\"word error\" sug=\"$counter\" space=\"yes\">" . fconvert("Arial Unicode MS", $translate, $str) . " </span><div class=\"suggestions $counter\">";
         else 
            echo "<span class=\"word error\" sug=\"$counter\" space=\"yes\">" . fconvert("Arial Unicode MS", $translate, $str) . "</span><div class=\"suggestions $counter\">";
        
        echo "<div id=\"sugwrds$counter\"><i>Loading suggestions...</i></div><hr size=\"1\" color=\"#ccc\"><span class=\"ignore\" idt=\"$counter\">Ignore</span><span class=\"ignoreall\" idt=\"$counter\">Ignore All</span><hr size=\"1\" color=\"#ccc\"><span class=\"suggdiswrd\" href=\"dialog/suggest?word=$str\" idt=\"$counter\" gur=\"box\">Suggest this word</span></div>";
     else 
        $note = mysql_query("SELECT note FROM unicode WHERE word = '$str'");
        if (mysql_result($note, 0) == "") 
            if ($space == "yes") 
                echo "<span class=\"whps\">" . fconvert("Arial Unicode MS", $translate, $str) . " </span>";
             else 
                echo "<span class=\"whps\">" . fconvert("Arial Unicode MS", $translate, $str) . "</span>";
            
         else 
            if ($space == "yes") 
                echo "<span class=\"whps blue\">" . fconvert("Arial Unicode MS", $translate, $str) . " </span>";
             else 
                echo "<span class=\"whps blue\">" . fconvert("Arial Unicode MS", $translate, $str) . "</span>";
            
            
        
    

punctuation.php（在 br 之前插入一个空格，以免与任何单词合并）

function punctuate($pstr, $font) 
    $repp = array(
        "  " => " ",

    if ($font !== "DrChatrikWeb") 
    $reppsq = array(

    );
    $repps = strtr($repps, $reppsq);
    
    return $repps;

这就是函数的执行方式...

$string = nl2br($_POST['string']);
$translate = $_POST['translate'];
checkspell($string, $translate);

一切正常。但它会在 br like 之后的下一个单词中插入一个空格。 这……

会输出这个....

How
<br>

第二个how中有一个空格，文本框中没有。

【参考方案1】：

我怀疑原因在于您的 punctuate() 函数：

"<br />" => " <br> ",

<br> 后面有个空格。

尝试以下方法：

"<br />" => "<br>",
//          ^    ^ Note the lack of spaces.

thxx fr ur answer...但是如果我这样做，它不会拆分它并将其与之前和之后的单词合并...这些空格是为了让拼写检查器认为这是一个词...
