PHP simple method to determine whether a string contains another string_php tips

The example in this article describes how PHP simply determines whether a string contains another string. Share it with everyone for your reference, the details are as follows:

When using PHP to determine whether a string contains a simple substring, we usually use the two functions strpos() or stristr(), but if the position of the string is in At index 0, that is to say at the beginning of the string to be matched, there will be a problem.

Of course we still have a solution. Here is a stupid solution, but it is easier to use. It applies to both Chinese and English punctuation marks.

The code is as follows:

function checkStr($str,$target)
{
  $tmpArr = explode($str,$target);
  //print_r($tmpArr);
  if(count($tmpArr)>1)return true;
  else return false;
}
$result = checkStr("sdfg","bsdfsldkfj");
var_dump($result);
