PHP计数器增加了一个额外的增量
[英]PHP counter adds an extra increment
问题描述
我基本上有一个简单的程序，该程序将一些文本作为表单的输入，将文本中的所有单词都匹配到两个词典。 一个词典包含一个肯定词列表，另一个包含一个否定词列表。 对于每个正词匹配，$ posMatchCount都会增加。 对于每个否定词匹配，$ negMatchCount都会增加。 进行了简单的比较，如果肯定词更大，则程序返回“ Positive”，否则返回“ negative”。 如果肯定词==否定词，或者没有正面或负面匹配，则返回“ Neutral”。 这是完整的代码：
<?php
include("positive_lexicon.php");
include("negative_lexicon.php");
?>
<html>
<head>
<title>Output</title>
</head>
<body>
<h1>Output</h1>
<hr>
<?php
$ preprocessedDoc2 =“我喜欢这款手机，但讨厌电池，我喜欢屏幕尺寸”；
/////////////////////////////////////////////////////////////////////////////////match doc text with POSITIVE sentiment lexicon
$matchedPosWords = NULL;//contains matched words
$posMatchCount = 0;//count of POS matches
$array1 = explode(' ', $preprocessedDoc2);
foreach($array1 as $word){
if(preg_match("/\s{$word}\s/", $positiveLexicon)){
$matchedPosWords = $matchedPosWords . $word . " - ";
$posMatchCount++;
$posMatch = true; //for subjectivity check
}
else{
$posMatch= false; //for subjectivity check
}
}
echo "Matched POSITIVE words: <br><br>";
echo "<div style=\"background-color:#66FF66\">";
echo $matchedPosWords . " (Total: {$posMatchCount})";
echo "</div>";
echo "<br><br>";
/////////////////////////////////////////////////////////////////////////////////match doc text with NEGATIVE sentiment lexicon
$matchedNegWords = NULL;//contains matched words
$negMatchCount = 0;//count of NEG matches
$array2 = explode(' ', $preprocessedDoc2);
foreach($array2 as $word2){
if(preg_match("/\s{$word2}\s/", $negativeLexicon)){
$matchedNegWords = $matchedNegWords . $word2 . " - ";
$negMatchCount++;
$negMatch = true; //for subjectivity check
}
else{
$negMatch = false; //for subjectivity check
}
}
echo "Matched NEGATIVE words: <br><br>";
echo "<div style=\"background-color:#FF5050\">";
echo $matchedNegWords . " (Total: {$negMatchCount})";
echo "</div>";
echo "<br><br>";
/////////////////////////////////////////////////////////////////////////////////comparison between POSITIVE and NEGATIVE words
echo "analyzing document's sentiment ...<br><br>";
function checkPolarity($posWords, $negWords, $posMatch1, $negMatch1){//function to check polarity of doc
if((($posMatch1==false) && ($negMatch1==false))||($posWords==$negWords)){
return "<strong>NEUTRAL</strong>"; //if there are no POS or NEG matches, or matches are equal, return NEUTRAL
}
if($posWords > $negWords){
return "<strong>POSITIVE</strong>"; //if count of POS matches is greater than count of NEG matches, return POSITIVE
}
else{
return "<strong>NEGATIVE</strong>"; //if count of NEG matches is greater than count of POS matches, return NEGATIVE
}
}
$polarity = checkPolarity($posMatchCount, $negMatchCount, $posMatch, $negMatch); //call function to check polarity
echo "Polarity of the document is: " . $polarity; //display overall polarity
echo "<br><br>";
$polarity = "";
?>
</body>
</html>
但是，即使肯定词的数量大于否定词，有时也会返回“神经”。 有时它会额外增加。 例如，字符串输入“我爱这部手机，但讨厌电池，我喜欢屏幕尺寸”，则返回以下内容：
Matched POSITIVE words:
love - adore - - (Total: 3)
Matched NEGATIVE words:
hate - - (Total: 2)
即使只有两个正匹配项和一个负匹配项，对于正匹配项，计数为3，对于负匹配项，计数为2。 我知道问题很快就会被发现，即使我似乎找不到它。 我会碰运气的..

我认为代码看起来没有错。 但是您输入的输出
Matched POSITIVE words:
love - adore - - (Total: 3)
Matched NEGATIVE words:
hate - - (Total: 2)
您在最后一个条目中有正或负匹配项的单个空格，我认为这是错误的。
如果愿意，请更改代码以进行调试和检查。
echo "Foreach for Positive words started <br/>";
foreach($array1 as $word){
if(preg_match("/\s{$word}\s/", $positiveLexicon) && trim($word) != "" ){
echo $word."= <br/>"; // there should be no empty word in this
$matchedPosWords = $matchedPosWords." - ". $word; // there should be no dash at the last, only word
$posMatchCount++;
$posMatch = true; //for subjectivity check
}
else{
$posMatch= false; //for subjectivity check
}
}
echo "Foreach for Positive words Ended <br/>";
