PHP : search for a string within a string

Question

I want to check whether a string is present in another string, and then take the appropriate action. What is the best way to do this?

For instance; if the string 'europe' is present in 'europeisthebest', then do something.

if ( isIn('europe', 'europeisthebest') == true){
  //do something
}

Thank you a lot! I appreciate all of your answers and time spent helping.

You're looking for strstr() (case sensitive), stristr() (case insenstive), or strpos()

if (stristr('europeisthebest', 'europe')){
  // do something
}

Hello John. Thank you. This is what I was looking for. I tried strpos previously but for some reason It wouldnt act correctly when I added ===true after the condition. Everything's good now. Thank you alot my friend.

@bornie That's because it doesn't return a boolean true; rather, it returns an integer if the string is found or a boolean false if it isn't. Using strpos to search for a string within a string can be accomplished like this: if( strpos('blah', 'blah') !== false ).

my string was like EX3.19 or EX7.99 and I wanted to search EX in the string... maybe because this might have caused the confusion... I dont know. Thank you for your answer.

You can also use the function strpos() if you wish to know the position of the substring inside the string
