Is it possible to call PHP function from url?
But please, for the love of all kittens, don’t abuse this. What your script does is entirely up to you. URLs cannot magically cause Apache, PHP, or any other server component to take a certain behavior, but if you write your program such that a particular function can be executed, it’s certainly possible.
What does url stand for in web development?
It is the mechanism used by browsers to retrieve any published resource on the web. URL stands for Uniform Resource Locator. A URL is nothing more than the address of a given unique resource on the Web. In theory, each valid URL points to a unique resource. Such resources can be an HTML page, a CSS document, an image, etc.
Can a URL point to something that no longer exists?
In practice, there are some exceptions, the most common being a URL pointing to a resource that no longer exists or that has moved. As the resource represented by the URL and the URL itself are handled by the Web server, it is up to the owner of the web server to carefully manage that resource and its associated URL.
Which is an example of an URL that does not use an authority?
One example of a URL that doesn’t use an authority is the mail client (mailto:foobar). It contains a scheme but doesn’t use an authority component. Therefore, the colon is not followed by two slashes and only acts as a delimiter between the scheme and mail address.

Is it safe to call function on global namespace in PHP?
