[Resolved] array_search

[Arc]

Hey guys. I am using the function array_search to see if a value excists in an array however it doesn't seem to be working.

Here is how I ma using it

$lanceArray=array(1 =>"Arkansas",1 =>"Iowa",1 =>"Kansas",1 =>"Louisiana",1 =>"Minnesota",1 =>"Missouri",1 =>"Nebraska",1 =>"North Dakota",1 =>"Oklahoma",1 =>"South Dakota",1 =>"Texas",1 =>"Wisconsin");

 if(array_search($_POST['selState'], $lanceArray)){
  echo "lance";
 }

I cannot get this to respond in any way. All the keys are 1 simply because I do not care what the key is, I just need to return a value to see if it excists in the array.

I have made sure that one of the values in the array are being passed, but still nothing.

Am I using this function incorectly?

Thanks!🙂

Are you saying that you're using keys as 1 in the REAL script, or just in this example? If you're doing it in the real script it means you'll end up with an array with only one element in it.

Also array_search returns the key for the found value, or false if it isn't found, so your if statement will fail if the element is key zero. So you must use the === (3 equals signs) test for false and !== false for true.

Thanks for your input, I appreciate it.

I went with in_array instead though and it works great.

Thanks again!😃
