How to make the url display hostname without www?
If the URL is
https://www.google.com/search/
How to make it like this?
google.com
My code
$rgx25 = '/\<a class\=\"live\" rel\=\"nofollow\" href\=\"(|https:\/\/|http:\/\/)(|www\.)(.*?)\" target\=\"\_blank\"\>(.*?)\<\/a\>/iu';
if (preg_match_all($rgx25, $story['text'], $matches))
{
foreach ($matches[0] as $k => $match)
{
$url = $matches[1][$k] . $matches[2][$k] . $matches[3][$k];
}
}
$url = 'http://sub.example.com/path?googleguy=googley';
$test = parse_url($url);
$string = explode('.',$test["host"]);
$top_lev_dom = array("com","net","us","gov","io","xyz","org","int","edu");
$output;
$end = false;
$pos = 0;
$pos2;
for($i = 0; $i < count($string); $i++){

$pos2 = $i - 1;
$end = true;
break;
}
if($end == true){break;}
}
if($end == true){break;}
}
if($pos==0){
$output = "error";
}else{
$output.=$string[$pos2].".".$string[$pos];
}
echo $output;

what i am trying to do is to get directory of my page like this
Home / Clothes / Something
i have tried this but i didn't understand a lot in this but it doesn't work as i want it
<?php
// current directory
echo getcwd() . "\n";
chdir('cvs');
// current directory
echo getcwd() . "\n";
?>
here's example what i need to do
my page is example.com/clothes/something.php
and on that page "something.php" i want to echo out something like this
Home / clothes / Something
i forget what this was called but hope you understand
<?php
$path = $_SERVER["PHP_SELF"];
$parts = explode('/',$path);
if (count($parts) < 2)
{
echo("home");
}
else
{
echo ("Home » ");
for ($i = 1; $i < count($parts); $i++)
{
if (!strstr($parts[$i],"."))
{
echo("<a href=\"");
for ($j = 0; $j <= $i; $j++) {echo $parts[$j]."/";};
echo("\">". str_replace('-', ' ', $parts[$i])."</a> » ");
}
else
{
$str = $parts[$i];
$pos = strrpos($str,".");
$parts[$i] = substr($str, 0, $pos);
echo str_replace('-', ' ', $parts[$i]);
};
};
};
?>
Try something like this:
$subPath = '';
$path = explode('/', $_SERVER['REQUEST_URI']);
array_shift($path);
foreach ($path as $segment) {
$subPath.= $segment.'/';
echo "$segment / ";
}
You may need to tweak it a bit, but that's the basic idea.
[EDIT]
Or maybe something like this:
$Pages = [
'/clothes' => 'Clothes',
'/clothes/something.php' => 'Something'
];
$subPath = '';
$BreadCrumbs = [];
$path = explode('/', $_SERVER['REQUEST_URI']);
array_shift($path);
foreach ($path as $segment) {
$subPath.= '/'.$segment;
$BreadCrumbs[] = "$Pages[$subPath]";
}
echo implode(' > ', $BreadCrumbs);
If your version of PHP is before 5.4.0, then you'll need a different syntax for the arrays:
$Pages = array(
'/clothes' => 'Clothes',
'/clothes/something.php' => 'Something'
);
$BreadCrumbs = array();
[EDIT]
OK, one last go:
<?php
$Pages = array(
'clothes' => 'Clothes',
'something' => 'Something'
);
$path = $_SERVER["PHP_SELF"];
$parts = explode('/',$path);
if (count($parts) < 2)
{
echo("home");
}
else
{
echo ("Home » ");
for ($i = 1; $i < count($parts); $i++)
{
if (!strstr($parts[$i],"."))
{
echo("<a href=\"");
for ($j = 0; $j <= $i; $j++) {echo $parts[$j]."/";};
echo("\">". str_replace('-', ' ', $Pages[$parts[$i]])."</a> » ");
}
else
{
$str = $parts[$i];
$pos = strrpos($str,".");
$parts[$i] = substr($str, 0, $pos);
echo str_replace('-', ' ', $Pages[$parts[$i]]);
};
};
};
?>
Zack here.. I've recently run into a spot of trouble with my URL Shortener.. Can you check the below code for errors? Thanks so much!
<?php
$db = new mysqli("localhost","pretzel_main","00WXE5fMWtaVd6Dd","pretzel");
function code($string_length = 3) {
$permissible_characters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$char_length = strlen($permissible_characters);
$random = '';
for ($i = 0; $i < $string_length; $i++) {
$random .= $permissible_characters[rand(0, $char_length - 1)];
}
return $random;
}
if (substr($_POST['long'], 0, 7) == http://) {
$url = $_POST['long'];
} elseif (substr($_POST['long'], 0, 8) == https://) {
$url = $_POST['long'];
} else {
$url = "http://".$_POST['long'];
}
$result = $db->prepare("INSERT INTO links VALUES('',?,?)");
$result->bind_param("ss",$url, $title);
$result->execute();
$title = $code();
?>
Good luck, and Thanks in advance!

Try this :
<?php
$db = new mysqli("localhost","pretzel_main","00WXE5fMWtaVd6Dd","pretzel");
function code($string_length = 3) {
$permissible_characters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$char_length = strlen($permissible_characters);
$random = '';
for ($i = 0; $i < $string_length; $i++) {
$random .= $permissible_characters[rand(0, $char_length - 1)];
}
return $random;
}
if (substr($_POST['long'], 0, 7) == "http://") {
$url = $_POST['long'];
} elseif (substr($_POST['long'], 0, 8) == "https://") {
$url = $_POST['long'];
} else {
$url = "http://".$_POST['long'];
}
$result = $db->prepare("INSERT INTO links VALUES('ss','$url','$title')");
$result->execute();
$title = code(); // no need of $ sign here
?>
My code cycles through a CSV file, converting it to XML:
<?php
for ($i = 1; $i < $arraySize; $i++) {
$n = 0;
if (substr($csv[$i][0], 0, 1) == $let) {
$surName = $dom->createElement('name');
$name = $csv[$i][0];
$nameText = $dom->createTextNode($name);
$surName->appendChild($nameText);
$text = str_replace(chr(94), ",", $csv[$i][4]);
$n = $i + 1;
$next = $csv[$n][0];
while ($next == 'NULL') {
$repl = str_replace(chr(94), ",", $csv[$n][4]);
$text = $repl;
$n++;
$next = $csv[$n][0];
}
$bio = $dom->createElement('bio');
$bioText = $dom->createTextNode($text);
$bio->appendChild($bioText);
$person = $dom->createElement('person');
$person->appendChild($surName);
$person->appendChild($bio);
$people->appendChild($person);
}
}
$xmlString = $dom->saveXML();
echo $xmlString;
?>
The problem is the $text = $repl; Typing $text .= $repl; brings:
error on line 1 at column 1: Document is empty.
but omitting the . just gives the last line of text.
the backup code works:
public function test($let){
$csv = $this->readCSV("data\AlphaIndex1M.csv");
$arraySize=sizeof($csv);
$let = strtoupper($let);
//echo '';
for($i=1; $i
echo $csv[$i][0];// .'
echo ', -->'.$csv[$i][4];
$n = $i+1;
$next = $csv[$n][0];
//if($next == 'NULL'){ }
while($next == 'NULL'){
echo $csv[$n][4]. " ";
$n++;
$next=$csv[$n][0];
}
//echo ''
echo '';
}
}
//echo ''
}
You have to initialize your $text before you can append stuff!
So write this before you use it:
$test = "";
(before the while loop or even before the for loop if you want all to be appended)
I'm creating a breadcrumb script like this:
<?php
if($location = substr(dirname($_SERVER['PHP_SELF']), 1))
$dirlist = explode('/', $location);
else
$dirlist = array();
$count = array_push($dirlist, basename($_SERVER['PHP_SELF']));
$address = 'http://'.$_SERVER['HTTP_HOST'];
echo 'home';
for ($i = 0; $i < $count; $i++)
echo ' » '.$dirlist[$i].'';
?>
If form url is http:// domain /school/students.php,
the result is like this: ( home » school » students.php )
Question: How to eliminate the extension .php file students.php,
be like this ( home » school » students ) ??
No matter how long is the extension or its name, this will work :
<?php
if($location = substr(dirname($_SERVER['PHP_SELF']), 1))
$dirlist = explode('/', $location);
else
$dirlist = array();
$count = array_push($dirlist, basename($_SERVER['PHP_SELF']));
$address = 'http://'.$_SERVER['HTTP_HOST'];
echo 'home';
for ($i = 0; $i < $count; $i++) {
$result = $dirlist[$i];
if ($i == ($count-1)) { // if last element
$lastDot = strripos($result,'.') ;
$result = substr($result,0,$lastDot) ;
}
echo ' » '.$result.'';
}
?>
how about using string replacement?
Here's a bit of code that may point you in the right direction, replacing your for loop.
for ($i = 0; $i < $count; $i++) {
$label = str_replace('.php', '', $dirlist[$i]);
echo ' » '.$label.'';
}
Try deducting string
<?php
if($location = substr(dirname($_SERVER['PHP_SELF']), 1))
$dirlist = explode('/', $location);
else
$dirlist = array();
$count = array_push($dirlist, basename($_SERVER['PHP_SELF']));
$address = 'http://'.$_SERVER['HTTP_HOST'];
echo 'home';
for ($i = 0; $i < $count; $i++)
if(!isset($dirlist[$i+1]))
{
echo ' » '.substr($dirlist[$i],0,-4).'';
}
else
{
echo ' » '.$dirlist[$i].'';
}
?>
this will work.
I find theese php codes here, but codes aren't working correctly. it seems that the if(isset($words[$word])) doesn't go through as I always get an empty results array
$boggle = "fxie
amlo
ewbx
astu";
$alphabet = str_split(str_replace(array("\n", " ", "\r"), "", strtolower($boggle)));
$rows = array_map('trim', explode("\n", $boggle));
$dictionary = file("C:/dict.txt");
$prefixes = array(''=>'');
$words = array();
$regex = '/[' . implode('', $alphabet) . ']{3,}$/S';
foreach($dictionary as $k=>$value) {
$value = trim(strtolower($value));
$length = strlen($value);
if(preg_match($regex, $value)) {
for($x = 0; $x < $length; $x++) {
$letter = substr($value, 0, $x+1);
if($letter == $value) {
$words[$value] = 1;
} else {
$prefixes[$letter] = 1;
}
}
}
}
$graph = array();
$chardict = array();
$positions = array();
$c = count($rows);
for($i = 0; $i < $c; $i++) {
$l = strlen($rows[$i]);
for($j = 0; $j < $l; $j++) {
$chardict[$i.','.$j] = $rows[$i][$j];
$children = array();
$pos = array(-1,0,1);
foreach($pos as $z) {
$xCoord = $z + $i;
if($xCoord < 0 || $xCoord >= count($rows)) {
continue;
}
$len = strlen($rows[0]);
foreach($pos as $w) {
$yCoord = $j + $w;
if(($yCoord < 0 || $yCoord >= $len) || ($z == 0 && $w == 0)) {
continue;
}
$children[] = array($xCoord, $yCoord);
}
}
$graph['None'][] = array($i, $j);
$graph[$i.','.$j] = $children;
}
}
function to_word($chardict, $prefix) {
$word = array();
foreach($prefix as $v) {
$word[] = $chardict[$v[0].','.$v[1]];
}
return implode("", $word);
}
function find_words($graph, $chardict, $position, $prefix, $prefixes, &$results, $words) {
$word = to_word($chardict, $prefix);
if(!isset($prefixes[$word])) return false;
**if(isset($words[$word])) {
$results[] = $word;
}**
foreach($graph[$position] as $child) {
if(!in_array($child, $prefix)) {
$newprefix = $prefix;
$newprefix[] = $child;
find_words($graph, $chardict, $child[0].','.$child[1], $newprefix, $prefixes, $results, $words);
}
}
}
$solution = array();
find_words($graph, $chardict, 'None', array(), $prefixes, $solution);
print_r($solution);
When you call find_words() at the end, you are only passing 6 parameters
find_words($graph, $chardict, 'None', array(), $prefixes, $solution);
The variable $words, is the 7th parameter in your definition of find_words()
function find_words($graph, $chardict, $position, $prefix, $prefixes, &$results, $words) {
Hence, $words will always be empty, and isset($words[$word]) will always be false
