Re: [PHP] Regular expression newbie question, convert this: [::word1\ word2 \ word3::] to : .word1 word2 word3.
hi dan,
its because the html text is from user input. and i dont wanna spend too
much time educating them on coding with php. sometime its a pain trying
to get them to understand the codes. so i just wanna give them some
simple commands in php whereby they can happily insert date formats on a
page. something like what phpBB did on the [url] thingie.

Why not merge your PHP and HTML straight up like this?
span class=normal?php echo date('m d y') . $phpVar; ?/span
Then, just have the whole HTML file parsed as PHP.

Re: [PHP] Regular expression newbie question, convert this: [::word1\ word2 \ word3::] to : .word1 word2 word3.
hi, thanks for the code. i tried. it only worked if the string is simply
the one i wanna convert. but that particular string is in the middle of
a long text, and there are multiple occurance, it won't.
however, i did manage to come up with this code that worked. but i
believe it can be improved on. it will identify all occurance of the
specified pattern and do the necessary replacement throughout the whole
string.
preg_match_all(|\[::(.*)::\]|U, $longTxt, $matchedResult);
for ($idx = 0; $idx count($matchedResult[1]); $idx++) {
$extract = stripslashes($matchedResult[1][$idx]);
$longTxt = str_replace([::{$matchedResult[1][$idx]}::],
\.$extract.\, $longTxt);
}

While I don't know if this is really what you need, it does do exactly
what you want to do in your example:
$Replace['\\'] = '';
$Replace['::'] = '.';
$Replace['['] = '';
$Replace[']'] = '';
$UserInput = '[::word1 \ word2 \ word3::]';
echo strtr($UserInput, $Replace);

Strange. It should work regardless of length. Couple things. Could you please provide an example of the text you're trying to convert and explain why you have this weird format and why you need the other unusual format. We may be able to come up with something far more straight forward. --Dan -- PHP classes that make web design easier SQL Solution | Layout Solution | Form Solution sqlsolution.info | layoutsolution.info | formsolution.info T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y 4015 7 Av #4AJ, Brooklyn NY v: 718-854-0335 f: 718-854-0409 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

hi, i was developing an application that will read in the content of a html file. and within this html file contains php variables which will be replaced using the eval() function with its required value. and within this html, i want to be able to run php functions. however, due to the fact that characters need to be escaped so that eval() can process it, i have to make use of addslashes() to escape all that are embedded in the html file. with the escaped, eval() will be able to work and evaluate the php variable and instead of: eval(\$rs = \span class=normal$phpVar/span\;); (won't work) it will now be: eval(\$rs = \span class=\normal\$phpVar/span\;); (work) and to call a date() function on the above text, this format will work: eval(\$rs = \span class=\normal\.date(m d y).$phpVar/span\;); since the text that is passed into eval() came from a html/php/inc (whatever you name it) file, there is no way you will know that a particular text is in fact a php function. so i thought of prefixing and suffixing php function with [::date(m d y)::] and it will be helpful in the sense that the application will know that oh, this is a php function, i need to . . it so that eval will not throw me an error. with that, now the html file's content will be something like: span class=normal[::date(m d y,$phpVar)::]/span after using addslashes(), it will be: span class=\normal\[::date(\m d y\,$phpVar)::]/span for the above text, in order for eval() to parse correctly, it has to be in this format: eval(\$rs = \span class=\normal\.date(m d y,$phpVar)./span\;) and there is always a chance that the html text could contain more than 1 block of [:: phpfunction ::] thats why i came up with that piece of code to convert the text to a string that eval will be able to understand. and at the end of it, i will be echoing $rs to display the final result. you probably will wonder why dont i use include() and require()? that way, php will be handling all the above without requiring additional work. however, due to the way the result has to be handled, i couldn't use include nor require. lance -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
