Replace any text from html text by tag name in php

function replace_tag_text($tagName,$subjectStr,$replaceStr) {
$tagName = preg_quote($tagName);
$result = str_replace($matches[1],$replaceStr,$subjectStr);
return $result;

Usage :
Say for Example

$ActualStr : ‘<div><span style=”margin: 0px 0px 0px 0px; width: 540px;”>something</span><p style=”float: right; margin: -240px 0 0; width: 200px;”>This is the actual String</p></div>’;

Then you can do as below:

$replacedStr  = replace_tag_text(‘div’,$ActualStr,$StrToReplaceWith);

Create template specific to node in drupal 6

If you want to have custom templates for your node. You can create templates specific to node ID as follows.

Add the below function in your template.php if its not exists.

function yourcurrentthemename_preprocess_node(&$vars, $hook) {
$node = $vars[‘node’];
$vars[‘template_file’] = ‘node-‘. $node->nid;

If the function already exists then add the two lines at the beginning of the function.

Then clear the cache.

So if you want to have a custom template for node id 3 (say for example) then create a template with name node-3.tpl.php in your theme directory.

Now you can customise your template as you need.

Keep Rocking…..Enjoy 🙂
