查找多维关联数组中的最后一个字符并删除它

Question

我在foreach中有一个这样的关联数组:

foreach ($mArray as $aValue) {
 foreach ($aValue as $key => $value) {
echo $html->find($key,$value)
}
}

它给我这样的输出:

bobby
johnny

现在我想获得最后一个字符，即y，所以我这样做:

echo substr($TheString, -1);

但是这给了我:yy因为它是一个多维数组所以它给了我每个数组的最后一个字符。我能做些什么来获得页面上的最后一个字符y (..然后删掉)?

Answer 1

$last_char = '';
foreach ($mArray as $aValue) {
        foreach ($aValue as $key => $value) {
            if(substr($html->find($key,$value), -1) == 'y'){
                $last_char = $html->find($key,$value);
            }
        }
    }
  echo $last_char;

Answer 2

这似乎对我有用

echo substr_replace($TheString,"",-3);

Answer 3

Try This:

echo substr($TheString, -1, 1);

或替换字符串删除y

$s="abcdey";
$m=substr($s,0,-1);
echo substr_replace($s,$m,0)

Try This:

        $array = array(
        "foo" => "jonny",
        "bar" => "monny",
        );
                     $i=0;
         $con=count($array);
         foreach($array as  $key => $value)
        {
         $i++;
         if($i==$con)
         {
         $s=$value;
         $m=substr($value,0,-1);
         $value=substr_replace($s,$m,0);
         echo "Removed Y from array of last item =".$m."</br>";
         }
         echo $value."</br>";
         }
