如何判断包含某个中文字?

$str=array("西瓜","苹果","香蕉")$str_long="西瓜很大颗";

回复讨论(解决方案)

哪个判断哪个？

$str_long句子里有没有包含阵列里面的字

$arr=array("西瓜","苹果","香蕉");$str_long="西瓜很大颗";foreach($arr as $k=>$v){	if(strpos($str_long,$v)!==false){		$exists[]=$v;	}}echo "
";print_r($exists);echo "
";/*Array(    [0] => 西瓜)*/

$str=array("西瓜","苹果","香蕉");$str_long="西瓜很大颗";if(strlen($str_long) != strlen(str_replace($str, '', $str_long))) {  echo '存在';}

$count = 0;
str_replace($str, '', $str_long, $count);
if( $count > 0 ){
//echo "存在";
}
