[php] Check if URL has certain string with PHP

I would like to know if some word is present in the URL.

For example, if word car is in the URL, like www.domain.com/car/ or www.domain.com/car/audi/ it would echo 'car is exist' and if there's nothing it would echo 'no cars'.

This worked for me:

// Check if URL contains the word "car" or "CAR"
   if (stripos($_SERVER['REQUEST_URI'], 'car' )!==false){
   echo "Car here";
   } else {
   echo "No car here";
   }

If you want to use HTML in the echo, be sure to use ' ' instead of " ".
I use this code to show an alert on my webpage https://geaskb.nl/ 
where the URL contains the word "Omnik" 
but hide the alert on pages that do not contain the word "Omnik" in the URL.

Explanation stripos : https://www.php.net/manual/en/function.stripos

strstr didn't exist back then?

if(strstr($_SERVER['REQUEST_URI'], "car")) {
   echo "car found";
}

This must be one of the easiest methods right?

Have a look at the strpos function:

if(false !== strpos($url,'car')) {
    echo 'Car exists!';
}
else {
    echo 'No cars.';
}

Surely this is the correct way round....

$url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];


if (!strpos($url,'mysql')) {
echo 'No mysql.'; //swapped with other echo statement
} else {
echo 'Mysql exists.';
}

Otherwise its reporting the opposite way it should...

$url = " www.domain.com/car/audi/";
if (strpos($url, "car")!==false){
    echo "Car here";
}
else {
   echo "No car here :(";
}

See strpos manual

You can try an .htaccess method similar to the concept of how wordpress works.

But I'm not sure if thats what your looking for exactly per say..

I think the easiest way is:

if (strpos($_SERVER['REQUEST_URI'], "car") !== false){
// car found
}

Starting with PHP 8 (2020-11-24), you can use str_contains:

if (str_contains('www.domain.com/car/', 'car')) {
   echo 'car is exist';
} else {
   echo 'no cars';
}

worked for me with php

if(strpos($_SERVER['REQUEST_URI'], 'shop.php') !== false){
echo 'url contains shop';
}

$url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];


if (!strpos($url,'car')) {
    echo 'Car exists.';
} else {
    echo 'No cars.';
}

This seems to work.

if( strpos( $url, $word ) !== false ) {
    // Do something
}

Try something like this. The first row builds your URL and the rest check if it contains the word "car".

$url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];


if (strpos($url,'car') !== false) {
    echo 'Car exists.';
} else {
    echo 'No cars.';
}
