php：如何检查字符串是否包含任何列出的关键字？

问题描述：

i have an array of strings.

I have an array of keywords.

i loop through each string, and need to store them to mysql database if it contains any of the keywords.

currently i am using multiple stristr(), which is getting difficult.

is it possible to do something like stristr($string, array("ship","fukc","blah")); ?

我有一个字符串数组。 p>

我有一组关键字。 p>

我循环遍历每个字符串，如果它包含任何关键字，则需要将它们存储到mysql数据库。 p>

目前我正在使用多个字符串 stristr（），这很难。 p>

是否可以执行类似stristr（$ string，array（“ship”，“fukc”，“blah”））的操作） ; code>？ p> div>

答

I would advice you to use regular expresion for that

snipet:

preg_match_all('|(keyword1|keyword2|keyword3)|', $text, $matches);
var_dump($matches);

see the documentation of preg_match_all for reference

答

try using in_array()

for ($i = 0 ; $i < count($arrayString); $i++){

  for ($j = 0 ; $j < count($arrayKeyWord); $j++){

    if (in_array($arrayString[$i],$arrayKeyWord[$j]) == true){
      /* mysql code */

    }

  }

}

答

$to_be_saved = array();
foreach($strings as $string) {
  foreach($keywords as $keyword) {
     if(stripos($string, $keyword) !== FALSE){
        array_push($to_be_saved, $keyword);
     }
  }
}

/*save $to_be_saved to DB*/

答

foreach ( $strings as $string ) {
  foreach ( $keywords as $keyword ) {
    if ( strpos( $string, $keyword ) !== FALSE ) {
      // insert into database
    }
  }
}

答

if(in_array($string, array("ship","fukc","blah")))
{

}
