how to check if URL exists with codeigniter ?
I didn't find and try to do it with simple php but it is not as easy as I read. Maybe because php change and what works 10 years ago does not work today in 2025 with php 8 (I forget the decimal)
I try
curl_init($url))
$headers = get_headers($url);
and differents easy solution but when I really check it it accept that it should not or I got php error message
Do codeigniter have already done solution ?
I even try if ( file_get_contents($url, 'FILE_TEXT', NULL, 0, 1))
But I got this kind of error file_get_contents(): php_network_getaddresses: getaddrinfo for aaaaaaa failed: Temporary failure in name resolution
instead of true false
I try catch but always have erors impossible to say if I have any kind of error it is false

Are you checking if a url exists or if a file exists?
RE: hot to check if url exists - captain-sensible - 04-13-2025
lets re-phrase the question.
if someone enters a URL like : domain.com/elephant
does that URL cause an event like loading a view or does something else; id that what you mean ?
for a view you can do something in a controller like
Code:
public function showView($page)
{
$this->logic1= file_exists(APPPATH."Views/".$page.".php");
if( $this->logic1 == 1 )
{
load view
}
else
{
load view called info which states , page poes not exits
}rout to pick up is :
Code:
$routes->get('(:any)','Pages::showView/$1');
//where Pages is a controller class and showView a method of the class using code aboveRE: how to check if url exists - InsiteFX - 04-14-2025
