How to Remove a Query String from a URL in PHP?

How to Remove QueryString and Retrieve URL

Your current code retrieves the full URL, including any query parameters. To extract only the URL without the querystring, you can utilize specific PHP functions.

Using strtok

The strtok() function effectively extracts the substring before the first occurrence of a delimiter, in this case, the question mark (?):

$url = strtok($_SERVER["REQUEST_URI"], '?');

This method provides a straightforward way to obtain the desired result.

Alternatives and Considerations

While strtok() is recommended, other approaches include:

• strstr() with the true argument: This approach is not as reliable as strtok().
• explode() with a limit of 2: This method creates an array with two elements, the first being the URL without the querystring.
• substr() and strrpos(): While suitable for certain cases, these methods may break if the querystring is missing or not correctly formatted.

Additional Notes

• The code sample provided in the question should return proper URLs regardless of the querystring.
• Use caution when replacing the entire codeblock, as it may introduce unexpected side effects.
• Consider testing these methods with various URL formats to ensure accuracy.
