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; ?> |
