How to get current url with PHP

Question

I have this link below.

http://example.com/Novo/adm/categoria/1-Nome_Categoria

http://example.com/Novo/adm.php?categoria=1

However I will need to compare current URL, to make a menu activation scheme.

Below the code displaying this result above.

<?php 
    $URL_ATUAL= "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
    echo $URL_ATUAL;
?>

For need to make this comparison I just need to get the URL below.

adm/categoria/1-Nome_Categoria

I tried to use the explode but did not return the correct URL.

Answer 1

As stated in the comments, the content of the global variable $_SERVER["REQUEST_URI"] is the way:

Novo/adm/categoria/1-Nome_Categoria

It was also stated in the comments that the content of interest is only the part of adm from then on, just treat this value by removing that which is not of interest. This can be done in various ways.

If the directory name is not changed over time, just removing the contents of the string is enough:

$url = str_replace("Novo/", "", $_SERVER["REQUEST_URI"]);

In this way, $url would be adm/categoria/1-Nome_Categoria, as desired.

If the directory name is subject to change over time, but there is always a directory, you can only remove the first snippet of the string until the first occurrence of /:

$url = substr($_SERVER["REQUEST_URI"], strpos($_SERVER["REQUEST_URI"], '/')+1);

The result will be the same, regardless of what the directory name is, as long as there is a.

If there is a possibility that there is more than one directory, but that the URL will always start with adm, you can search for this snippet in your URL, this way:

$url = substr($_SERVER["REQUEST_URI"], strpos($_SERVER["REQUEST_URI"], 'adm'));

The result would also be the same, regardless of the number and name of directories present in the URL.

I have a very nice class for this task, feel free to use it, opinion, study, etc...

This would be the form of use of the same:

<?php $uri = URI::base(); echo $uri; ?>

or only...

<?php echo URI::base(); ?>

Below the structure of the class

<?php
class URI {

/**

{
    /**

    if(strpos(strtolower($_SERVER['SERVER_PROTOCOL']),'https') === false)
    {
        self::$protocolo = 'http://'; //Atribui o valor http

    else
    {

    return self::$protocolo;

    {

    else
    {

    }
    /**

    return self::$scriptName;
}
/**

Answer 3

can use

<?php
echo $_SERVER['SCRIPT_URI'];
?>

or the short form

<?=$_SERVER['SCRIPT_URI']?>
