Tag Stripping in PHP.....

Anon

In a PHP script of mine I have need to read a HTML file into a string, and do a search for all of the custom '[content]' tags I have put in the HTML, as the script will replace these. An example being ...

<td width="131" height="264">[CONTENT name="side" src="side.txt"]</td>

What I would like to do is to be able to read in to an array the name and scr parameters of the content tags I have defined so my script can replace these content tags with the information in the src parameters.

I have tried using while ... eregi to strip out the content tags and found it continuly looped on the first 'content' it found. I thought that split would be a good way of obtaining the imformation, but my pattrern matching (regex) handling skills are limited as I am vey new to the language, and therefore I am only able to do the revese of what I intend to do, that is read everything BUT the content tags in to the array,

eg:

$fl_array = spliti ("[^([CONTENT ([^[]*)])]", $data);

how do I make this so it splits at anything that is inbetween the content tags ?

Thanks for reading

very messy and I know there must be a way to clean it up so it only needs $data = ... and a spliti command with embedded regex's/pattern matching to rip the tag contents out :S

Here is my messy code ...

$data = implode("\n\t", file($page));

///* OK but messy code!
$fl_array = spliti ("[CONTENT", $data);
$i=0;
foreach ($fl_array as $fl_arrayline)
{
$stuff = strstr($fl_arrayline,"]");
if ($stuff)
{
$content[$i] = eregi_replace($stuff,"",$fl_arrayline);
$i++;
}
}

I attempted to email you, but heres the contents of the email. Enjoy, feel free to email me back comments/problems.

Hola =)

I saw your post on PHPBuilder and was JUST about to post something like that. I am attempting to do very much the same sort of thing. And now that I sat to write this email half an hour ago, I found a lot cleaner solution, using Perl-style regex (much faster than ereg)…

Adapt as you require. :-)

In the HTML file I have:

It is read into the variable $line, whichever way you want to do it.

if(preg_match('/<Event\s(.*?)>/i', $line, $matches)) {

        $array = explode(' ', $matches[1]);

        $settings = array();

        foreach($array as $value)

                    $newarray[substr($value,0,strpos($value,'"')-1)] = substr($value, strpos($value,'"')+1, -1);

}

After the above code (It is in a loop in my code – I read the file using file() which makes an array… I just test every element of the array), you would get:

Array(

        [type]    => death

        [time]    => imminent

        [style]   => bloody

)

No need to assign additional variables.. its all in one neat array =)

Also, a tip. Since preg is obviously expensive (as far as system clocks)… I use a simple strops before the preg. Ex:

for($i = 0; $i < strlen($file); $i++) {

        $line = $file[$i];

        if(str_pos(strtolower($line), ‘<event’)===false) {

                    # Not Found on this line

                    # The way I do it is this block assigns this line to the “output” variable… it doesn’t contain code we need to

                    # edit, so we can just tack it on to the output =)

                    $output .= $line . “\n”; # I think when I did $file = file(‘test.x’); it strips \n\r’s .. let’s add one in to be safe.

                    continue;

        }

        # preg here…

}

I hope this helped you out… I sure learned quite a bit from it =)

Adendum

Above, it should be:

settings = array();

foreach($array as $value)

$settings[substr($value,0,strpos($value,'"')-1)] = substr($value, strpos($value,'"')+1, -1);

Oops. =)
