Question

我实际上正在制作拼写检查程序。我要做的是将字符串按空格分成单词，添加标记以忽略标点符号，并使用nl2br()函数保留<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，甚至为下一个单词添加一个空格。在这里，我将向您展示代码......

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，以便它不会与任何单词合并）

function punctuate($pstr, $font) {
    $repp = array(
        "  " => " ",
        "<br />" => " <br> ",
        " ।" => " <punc>।</punc> ",

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

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

这是函数的执行方式......

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

一切都很好。但它会在下一个单词之后插入一个空格。此...

将输出此....

第二个how中有一个空格，文本框中没有空格。

Answer 1

我怀疑原因在于punctuate()功能：

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

<br>之后有一个空格。

尝试以下方法：

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

<br/>在下一个foreach项目中插入空格
