Check if a characters occurs once in URL

My Question

I want to check if the URL contains one ? if true, do something

My PHP

Im using this script currently. 

$lp_uri = $_SERVER['REQUEST_URI']; // or taken from another source //
    if( strpos($lp_uri, '?') !== false ){
    echo '<script>alert("one question mark");</script>';
}

My Issue

Im not sure how to check if the? occurs once only. Can you please help? Thanks heaps

The reason

I have a contact form on my website and once someone submits it, it addds a parameter to the url so it look like website.com?msgsent=1. This means the message has been send. But sometimes if the email field is incorrect, it still adds a ? to the url so the url looks like website.com?.

Now, I am using a jQuery slideDown delay on my contact form to grab customers attention and everytime the page refreshes, it takes few seconds to slideDown. I want to overcome this if the url has a ? in it because if the url looks website.com? that means, the email address is wrong.

Hope this makes sense.

The solution for the initial question (just in case someone will find this question on google) is to use substr_count:

if(substr_count($text, '?') == 1){
    // do something
}

The solution to your problem would be to check if the msgsent parameter is set:

if(!isset($_GET['msgsent'])){
    // message not sent - do something
}

A possible solution making use of the offset optional parameter

<?php
if( strpos($lp_uri, '?') !== false ){ 
   //1 or more question marks
   $pos = strpos($lp_uri, '?');  //Grab the position of it
   if(strpos($lp_uri, '?',$pos) === false) {
      //No more after the first, hence only 1
   }
}
