| | Hello..
Im looking for some help.
I want to use preg_replace function to replace the following type of code tags.CODE <code lang="php"></code>
<code lang="javascript"></code>
<code lang="css"></code>
My question is that, in the above code tags, language (lang) is not always same, how can i use preg_replace with the above code tags to place them with something.
Any help will be very much appreciated.
thanks. |

You would need preg_replace_callback() instead. Here's an example code to get you started: CODE <?php
$str = '<code lang="php"></code>
<code lang="javascript"></code>
<code lang="css"></code>';
function parse_code($matches){
if ($matches[1] == "php"){
return "[ code ]".$matches[2]."[ /code ]";
} else if ($matches[1] == "javascript"){
return "[ code ]".$matches[2]."[ /code ]";
} else if ($matches[1] == "css"){
return "[ code ]".$matches[2]."[ /code ]";
}
}
$str = preg_replace_callback("/<code lang=\"(\w+)\">(.*)<\/code>/", "parse_code", $str);
echo $str;
?>

truefusion may make a mistake in 18th line, try this: CODE <?php
$str = '<code lang="php"></code>
<code lang="javascript"></code>
<code lang="css"></code>';
function parse_code($matches){
if ($matches[1] == "php"){
return "[ code ]".$matches[2]."[ /code ]";
} else if ($matches[1] == "javascript"){
return "[ code ]".$matches[2]."[ /code ]";
} else if ($matches[1] == "css"){
return "[ code ]".$matches[2]."[ /code ]";
}
}
$str = preg_replace_callback("/<code lang=\"(\w+)\">(.*)<\/code>/", "parse_code", $matches);
echo $str;
?>

Simple Javascript And Password System

pass the "input" directly through the url by changing the .href, like

How Often Do You Use Css?
As opposed to using simple <font> and <div> tags (12) CSS is basically made to make your html coding a heck of a lot easier. However, sometimes I prefer
to use html instead of CSS since it sometimes gets frustrating to refer to the same old style sheet
and use an old font ID you made about a week ago. I find it a lot more efficient to just type out
the specified font color/style/size in the tag than to use an individual or for certain fonts
you'd like to use. Sure, it's very helpful a lot of the time to use CSS in most cases, since
it's kind of like a very simplified version of PHP but in a different case,....
