PHP計數器增加了一個額外的增量
[英]PHP counter adds an extra increment
問題描述
我基本上有一個簡單的程序，該程序將一些文本作為表單的輸入，將文本中的所有單詞都匹配到兩個詞典。 一個詞典包含一個肯定詞列表，另一個包含一個否定詞列表。 對於每個正詞匹配，$ posMatchCount都會增加。 對於每個否定詞匹配，$ negMatchCount都會增加。 進行了簡單的比較，如果肯定詞更大，則程序返回“ Positive”，否則返回“ negative”。 如果肯定詞==否定詞，或者沒有正面或負面匹配，則返回“ Neutral”。 這是完整的代碼：
<?php
include("positive_lexicon.php");
include("negative_lexicon.php");
?>
<html>
<head>
<title>Output</title>
</head>
<body>
<h1>Output</h1>
<hr>
<?php
$ preprocessedDoc2 =“我喜歡這款手機，但討厭電池，我喜歡屏幕尺寸”；
/////////////////////////////////////////////////////////////////////////////////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，即使肯定詞的數量大於否定詞，有時也會返回“神經”。 有時它會額外增加。 例如，字符串輸入“我愛這部手機，但討厭電池，我喜歡屏幕尺寸”，則返回以下內容：
Matched POSITIVE words:
love - adore - - (Total: 3)
Matched NEGATIVE words:
hate - - (Total: 2)
即使只有兩個正匹配項和一個負匹配項，對於正匹配項，計數為3，對於負匹配項，計數為2。 我知道問題很快就會被發現，即使我似乎找不到它。 我會碰運氣的..

我認為代碼看起來沒有錯。 但是您輸入的輸出
Matched POSITIVE words:
love - adore - - (Total: 3)
Matched NEGATIVE words:
hate - - (Total: 2)
您在最后一個條目中有正或負匹配項的單個空格，我認為這是錯誤的。
如果願意，請更改代碼以進行調試和檢查。
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/>";
