Question

我想问一下如何解决我的问题我已经有了代码：

for ($i = 0; $i < count($kataDasar); $i++) {
    for ($j = 0; $j < count($kataDasar1); $j++) {
        $jml = 0;
        if ($kataDasar[$i] == $kataDasar1[$j]) {
            $jml++;
        }
    }
    $tf[$i][$j] = $jml;
}

问题是，当我使用变量$kataDasar进行循环时，它会使$tf[$i][$j]的值错误，它应该与其他变量$paragraf循环，当我进行

时

for($i=0; $i<count($paragraf); $i++)

比较效果不好..任何人都可以帮我解决问题..

这里是我的完整代码

        echo '<p><b>Pemecahan Steamming</b></p>';
    print_r($kataDasar);
     echo "<br/><br/>";

    $kataDasar1 = Array();
foreach($kataDasar as $item){
        if($item != ''){
                if(!in_array($item, $kataDasar1) ){
                    $kataDasar1[] = $item;
                }
            }
        }

    print_r($kataDasar1);
     echo "<br/><br/>";

从您的代码中。您将$ kataDasar与增量变量循环为$ k并使用$ i访问它。您应该与正确的增量变量进行比较。这应该是正确的事情：

for($k=0; $k<count($kataDasar); $k++){
for($j=0; $j<count($kataDasar1); $j++){
$jml = 0;
if ( $kataDasar[$k]== $kataDasar1[$j] ){
$jml++;
}
// }
$tf[$i][$j] = $jml;
