我有两大类刮取的产品名称和价格类似于以下内容:
$one=array('grape'=>'0.40','apple'=>'1.20','banana'=>'1.80','lemon'=>'10.43');
$two=array('grappe'=>'1.20','kiwi'=>'7.54','banaana'=>'3.20','aubergine'=>'2.32');
我试图使用similar_text函数迭代数组,以返回彼此紧密匹配的键。例如,我想从上面的示例中提取'grappe'=>'1.20'
和'banaana'=>'3.20'
的值。
我不确定如何引用数组并将它们传递给similar_text函数,因为此函数只接受字符串数据。我假设我需要使用foreach
循环正确引用数组,并使用 if 语句与similar_text
函数一起指定两者之间所需的相似百分比火柴。
例如(在foreach循环中):
if ($result[] = (similar_text( $one, $two)) > 80) {
var_dump($result[]);
}
答案 0 :(得分:2)
similar_text( $one, $two)
返回两个字符串中匹配字符的数量,以便获得百分比,您应该运行similar_text($one, $two, $percent);

示例
$one = array('grape' => '0.40','apple' => '1.20','banana' => '1.80','lemon' => '10.43');
$two = array('grappe' => '1.20','kiwi' => '7.54','banaana' => '3.20','aubergine' => '2.32');
$result = array();
foreach ( $one as $key => $value ) {
foreach ( $two as $twoKey => $twoValue ) {
similar_text($key, $twoKey, $percent);
if ($percent > 80) {
$result[$key] = array($value,$twoValue);
}
}
}
var_dump($result);
输出
array
'grape' =>
array
0 => string '0.40' (length=4)
1 => string '1.20' (length=4)
'banana' =>
array
0 => string '1.80' (length=4)
1 => string '3.20' (length=4)
