I'm trying to get the last number after the last dash that is the last rallite - of a string like this

Profesores-de-Barahona-demandan-calidad-del-almuerzo-escolar-y-mejorar-plantas-fsicas-3

This string comes from a URL which the last number is the id of the post so I need to extract that id to then make a query to the database try with explode in this way but it returns me from the first dash -

$id=explode("-",$_GET["view"]);

this returns me de

Assuming that your $ GET ['view'] is a string:

<?php
 $cadena = "Profesores-de-Barahona-demandan-calidad-del-almuerzo-escolar-y-mejorar-plantas-fsicas-3";
 $part=explode("-",$cadena); 
 $id = end($part);
 var_dump($id);exit();

with the end () function of php you get the last element of an array

If all your URL are going to have at the end the id you need, you can simply do the following:

$cadena = "Profesores-de-Barahona-demandan-calidad-del-almuerzo-escolar-y-mejorar-plantas-fsicas-3";
$id = substr($cadena, -1);
echo $id;

You save in $id the number you want and then use it wherever you want. Greetings.

Is there any way to deny something like isinstance () in Python? Exceptions c ++ POO

You can do it as follows:

<?php

$cadena = "Profesores-de-Barahona-demandan-calidad-del-almuerzo-escolar-y- 
           mejorar-plantas-fsicas-3";

echo substr($cadena, strrpos($cadena, '-') + 1);

//RESULTADO 3

EXPLANATION

substr returns the specific part of a string

strrpos gets the last position where - appears

when using +1 we get the value that is after the last - which in this case is the number 3
