Question

I got lots of result and codes about search string. But all are search single word. I want to search multiple word and any of word match string will be display.

Example:

$string = "Apple is a big tech company!";
$search = 'Apple Logo';

Now I want if "Apple Logo" or "Apple" or "Logo" in string then it will return True else it will show False.

How I do that? I already tried lot of PHP codes. I also see ElasticSearch but I want something handy and easy to use.

if (stripos($string, $search) !== false) {
 echo "Found";
}

Answer 1

You can use an array of the words, replace them and check against the original:

if(str_ireplace(explode(' ', $search), '', $string) != $string) {
    echo "Found";
}

Or loop the words and check as you would with a single word:

foreach(explode(' ', $search) as $word) {
    if(stripos($string, $word) !== false) {
        echo "Found";
        break;
    }
}

Answer 2

我会使用preg_grep和其他一些奇特的东西。

$string = "Apple is a big tech company!";
$search = 'Apple Logo a';

$pattern = '/\b('.str_replace(' ', '|', preg_quote($search, '/')).')\b/i';

$arr = preg_grep($pattern, explode(' ', $string));

print_r($arr);

输出

Array ( [0] => Apple [2] => a )

我把a扔在那里只是为了炫耀。如您所见，它只匹配a而非company等。

作为奖励，它将正确地逃避搜索字符串中的任何正则表达式内容......

耶！

作为旁注，如果您愿意，也可以使用与preg_match_all相同的模式。

$string = "Apple is a big tech company!";
$search = 'Apple Logo a';

$pattern = '/\b('.str_replace(' ', '|', preg_quote($search, '/')).')\b/i';

$numMatch = preg_match_all($pattern,$string,$matches);

print_r($numMatch);
print_r($matches);

输出

 2
 Array (
      [0] => Array (
           [0] => Apple
           [1] => a
      )
      [1] => Array (
           [0] => Apple
           [1] => a 
      )
 )

唯一真正的区别是你得到一个更复杂的数组（只需使用$matches[1]）和匹配计数而不计算所说的数组。

you can use this STRPOS example:

$a = 'How are you?';

if (strpos($a, 'are') !== false) {
    echo 'true';
}

this a little example.. good luck
