将字符串与PHP中的字符串数组进行比较？

Question

I have a string like abcdefg123hijklm. I also have an array which contains several strings. Now I want to check my abcdefg123hijklm and see if the 123 from abcdefg123hijklm is in the array. How can I do that? I guess in_array() wont work?

Thanks?

Answer 1

So you want to check if any substring of that particular string (lets call it $searchstring) is in the array? If so you will need to iterate over the array and check for the substring:

foreach($array as $string)
{
  if(strpos($searchstring, $string) !== false) 
  {
    echo 'yes its in here';
    break;
  }
}

See: http://php.net/manual/en/function.strpos.php

If you want to check if a particular part of the String is in the array you will need to use substr() to separate that part of the string and then use in_array() to find it.
