This is a way to sanitize a string to be used as file name or URL path etc. by removing unwanted characters or replacing them with a hyphen or similar.
It takes a string like:
Daily SimpliVity Backup 12/16/2018 02:00:215
and converts it into:
daily-simplivity-backup-12-16-2018-02-00-25
Clean up URL.s with parse_url() by:
* add "http://" if scheme is missing
* add correct "glue" (://) between scheme and host
<?php
$parse = parse_url($url);
if (empty($parse['scheme'])) {
$url = "http://".$url;
}else{
$url = $parse['scheme']."://".$parse['host'].$parse['path']. (!empty($parse['query']) ? "?".$parse['query'] : "") . (!empty($parse['fragment']) ? "#".$parse['fragment'] : "");
}
?><?php
function clean_url(&$hit_link) {
// Find the first occurency of "http://". If it's not at position zero remove everything before it.
$find = 'http://';
$url = $hit_link;
$pos = strpos($url, $find);
if($pos !== FALSE) {
// We found a http://, on what position?
if($pos > 0) {
$pos += 7;
$url = substr($url, $pos); //Removes the first "http://"
$hit_link = $url;
}
}
}
?>This is how you can extract a domain out of URL without the subdomains. The parse_url() function gives the domain with the subdomain and this function just take the last two pieces and return it put together.
If you have access to your own module you can add a hook_cron function with the following code. On each cron it will execute the bulk generation for nodes
<?php
function feed_control_cron(){
//If you want to change the number of nodes to change
variable_set('pathauto_max_bulk_update', 1000);
//include the .inc files of pathauto
_pathauto_include();
//Executes the generation of URL aliases for nodes
node_pathauto_bulkupdate();
}

This is how you can escape slashes in an URL with an backslash, before doing a preg_replace on the path part of the URL. I have used this before a validation of URL:s containing the swedish characters åäö.
This is how you can validate an URL by examining the pattern.
<?php
function validateURL($url) {
$pattern = '/^(([\w]+:)?\/\/)?(([\d\w]|%[a-fA-f\d]{2,2})+(:([\d\w]|%[a-fA-f\d]{2,2})+)?@)?([\d\w][-\d\w]{0,253}[\d\w]\.)+[\w]{2,4}(:[\d]+)?(\/([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)*(\?(&?([-+_~.\d\w]|%[a-fA-f\d]{2,2})=?)*)?(#([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)?$/';
return preg_match($pattern, $url);
}
?>
Or from Drupal 6
/**
* Verify the syntax of the given URL.
*
* This function should only be used on actual URLs.
This function checks if a given URL is valid by using fsockopen.
function is_valid_url ($url){
$url = @parse_url($url);
if ( ! $url) {
return false;
}
$url = array_map('trim', $url);
$url['port'] = (!isset($url['port'])) ? 80 : (int)$url['port'];
$path = (isset($url['path'])) ? $url['path'] : '';
if ($path == ''){
$path = '/';
}
$path .= ( isset ( $url['query'] ) ) ?
