我实际上正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()
保留<br>s
. 现在,问题是,当我说忽略 时br
,它会将其视为一个单词,甚至在下一个单词中添加一个空格。在这里,我将向您展示代码...
拼写检查器.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,这样它就不会与任何单词合并)

}
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 之后的下一个单词中插入一个空格……这……
How
How
会输出这个....
How
<br>
How
第二个中有一个空格,how
文本框中没有。
