I want a php function to make the output like

Let me know :)



You should use an array of "disallowed" terms and use strpos and str_replace to dynamically remove them from the passed-in URL:

function remove_http($url) {
   $disallowed = array('http://', 'https://');
   foreach($disallowed as $d) {
      if(strpos($url, $d) === 0) {
         return str_replace($d, '', $url);
   return $url;

You want to use implode for this.

ie: $commaList = implode(', ', $fruit);

There is a way to append commas without having a trailing one. You'd want to do this if you have to do some other manipulation at the same time. For example, maybe you want to quote each fruit and then separate them all by commas:

$prefix = $fruitList = '';
foreach ($fruits as $fruit)
    $fruitList .= $prefix . '"' . $fruit . '"';
    $prefix = ', ';

Also, if you just do it the "normal" way of appending a comma after each item (like it sounds you were doing before), and you need to trim the last one off, just do $list = rtrim($list, ', '). I see a lot of people unnecessarily mucking around with substr in this situation.

You can use the "e" modifier on preg_replace() (see Pattern Modifiers)

return preg_replace("/[video](.+?)[/video]/e", "embed_video('$1')", $Text);

which tells preg_replace() to treat the second parameter as PHP code.

Ok, let’s try this complete example of use:

function CatRemove($myXML, $id) {
    $xmlDoc = new DOMDocument();
    $xpath = new DOMXpath($xmlDoc);
    $nodeList = $xpath->query('//category[@id="'.(int)$id.'"]');
    if ($nodeList->length) {
        $node = $nodeList->item(0);

// test data
$xml = <<<XML
<?xml version="1.0"?>
 <data1>some data</data1>
 <data2>some data</data2>
 <data3>some data</data3>
 <category id="0">
  <categoryName>Cat 1</categoryName>
  <categorydata1>some data</categorydata1>
 <category id="1">
  <categoryName>Cat 2</categoryName>
  <categorydata1>some data</categorydata1>
  <categorydata2>some data</categorydata2>
  <categorydata3>some data</categorydata3>
  <categorydata4>some data</categorydata4>
// write test data into file
file_put_contents('untitled.xml', $xml);
// remove category node with the id=1
CatRemove('untitled.xml', 1);
// dump file content
echo '<pre>', htmlspecialchars(file_get_contents('untitled.xml')), '</pre>';

* in regex means to match the previous character 0 or more times, while ( starts a capturing group. So, the * has nothing to repeat, since what comes before the * is a (, which cannot be repeated by itself, hence this warning.

To fix it, just escape the *, like so:

$uid = preg_replace("#(*UTF8)[^A-Za-z0-9]#", "", $tmp);
