Do you mean that all the other tags return the proper content
except the last one? I didn't study the code too closely for
reasons that follow.
What's wrong?
Glad you asked :) Here are a couple things I noticed:
- every call to this function has the overhead of reading the
file.
- The parsing is error prone, ie. someone puts: bttag=bassie
If its possible I would take a complete different approach at
parsing the tags. There are two options that I see right away. Use
XML as your data format and an xml parser to obtain the values in
the tags. Or use preg_match_all. Here is how I would approach the
preg_match_all:
function parseTags($file) {
/* readfile... here */
$tag_match = !bttag=(\w*)\s*([^]*)\s*/bttag!is;
preg_match_all($tag_match, $filedata, $matches);
for ($i=0; $i count($matches[0]); $i++) {
$tagname = $matches[1][$i];
$tags[$tagname] = $matches[2][$i];
}
return $tags;
}
Then you can use it like so:
?php
$bttags = parseTags('test.tag');
?
HTML
BODY
h1Test readTag-functie/h1
?php echo $bttags['bassie']; ?
/body
/html

[PHP] I can't make 'read_tag.php' file
I have found that this script doesn't work:
read_tag.php
---
?php
function readTag($filename, $tagtype, $debug = 0) {
$filedata = file_get_contents($filename);
$tagrealname = bttag=;
$tagrealname .= $tagtype;
$tagrealname .= ;
$tagdata = stristr($filedata, $tagrealname);
$posofend = strpos($tagdata, /bttag);
$length = strlen($tagdata);
$lengthoftag = strlen($tagrealname);
$lengthofend = strlen(/bttag);
$lengthofstr = $length - $posofend - $lengthoftag;
$returndata = substr($tagdata, $lengthoftag, $lengthofstr);
if ($debug == 1) {
echo brLength = . $length;
echo brOf Tag = . $lengthoftag;
echo brOf Str = . $lengthofstr;
echo brOf End = . $posofend;
echo brTagData:br . $tagdata;
}
return $returndata;
}
?
HTML
BODY
h1Test readTag-functie/h1
?php echo readTag(test.tag, bassie, 1); ?
/body
/html

And with this, it needs the file 'test.tag'
---
bttag=bassie
I am myself!!
/bttag
bttag=test
This is a test!!!
/bttag
bttag=welcome
Welcome!!!
/bttag
bttag=close
Closing!!!
/bttag
---
The first parameter of the readTag function is the filename of the tag file.
The second is the tag to search for an the third is the debug mode.
The error is that if i load this, the readTag function returns everything
except for the Closing!!!
What's wrong?
