To check whether a string is a Substring of another

Hi all ,

Pls hlp me , i am a beginner ,

I want to check whether a string is substring of another string , how do i do that.....

substr returns the substring with the given start and end , but i just need to know , whether str1 is in str2....

Use strpos():

if (strpos($str2, $str1) !== false)
{
    // str1 is in str2
}
