php页面中
如

$content="abcdabdsdsdsaddfdaad";

1 需得到数组中 四个元素在$content上出现次数最高的元素（如果有二个元素出现次一样高，一并输出）thanks

$ar = array("a","b","c","d");
$content = "abcdabdsdsdsaddfdaad";

$t = array_count_values(str_split($content, 1));
$p = array_keys($t, max($t));

$r = array_intersect($ar, $p);
print_r($r);

多谢楼上的
array("a","b","c","d"); 其中a b c d不一定是个字母，可能是个变量

怎么把你的程序调整到通用呀，

通用的
$ar = array("a","b","30","d","我们");
$content = "abcd,30abd30,我们qssdsdsaddfdaad";

$p = join('|', $ar);

preg_match_all("/$p/" , $content, $r);

$t = array_count_values($r[0]);

$p = array_keys($t, max($t));

print_r($p);
