Like Shawn, I have tried your code in isolation and only get the expected
results. I looped it over a few test values:
?php
$valueList = array('','test','testtest','testamp;test');
echo pre\n\n;
foreach ($valueList as $value) {
echo Before: $value\n;
$value=preg_replace(%(?!amp;)%i, amp;, $value);
echo After: $value\n\n;
}
echo '/pre';
?
outputs (ignoring pre as that was just to remove the br / for easy
reading):
Before:
After:
Before: test
After: test
Before: testtest
After: testamp;test
Before: testamp;test
After: testamp;test
The only conclusion is that something else in your code is converting the
quotes. Have a look around.

[PHP] Re: preg_replace problem (or possibly bug)
What I see in the page you sent is a [url] bbcode-tag that is not closed (i.e. it has no [/url] or it's not displayed) If that's not the problem, could you send some example that isn't working (and some others that are working) Michael wrote: I am currently writing a forum system, but at the moment I have a bug that no one can seem to get to the root cause of. Basically I am using preg_replace with the pattern as '\[url=(.*?)\](.*?)\[/url\]'is. However for most links it works fine but for others it just doesn't render the bbcode to a link, we were trying to get to the root cause of it here http://michael-m.co.uk/forums/index.php?action=view_topicid=31page=1 but we failed. I'm not really that good with regular expresions so that might explain why. Also we had never noticed these problems until about 3 days ago, but I see no reason why it could have started. All help will be greatly appreciated, you may use the username php and the password php to log on to do your own tests but please keep the testing to the topic (and the spam forum if necessary).

[PHP] Re: preg_replace problem
Is there any special reason why you want to solve this with regular
expressions? As far as I see, there's a couple of problems with your code,
a) $file = dog.txt should be $file = 'dog.txt',
b) $getOldValue has the _array_ resulting of parsing the INI file,
hence you should write $getOldValue, since it's the complete file
(I won't say anything about performance),
c) you're using a regular expresion to increment the value in a
specific key/index, and you don't need regexp for that, and
d) you're not saving the whole file, only the setting (entry) for
today, hence you overwrite the file and leave only today = n
What do you think of something like this (a bit changed):
$file= 'dog.txt';
$today = date(Ymd);
// we read the file,
$getOldValue = parse_ini_file($file);
// set or increment the value in $today key,
@$getOldValue[$today] ++;
// and write back the whole INI file
// note: what we have is an array, not a string
$str_ini = '';
foreach ( $getOldValue as $date = $value ) {
$str_ini .= $date = $value\n;
}
file_put_contents($file, $str_ini);
Benjamin Adams wrote:
$file = dog.txt;
$today = date(Ymd);
function incDate($new, $date){
//$date = settype('int');
return $new.($date++);
}
$getOldValue = parse_ini_file($file, 1);
$newValue = $getOldValue[$today] + 1;
$oldDate = $today . = . $newValue;
$newDate = preg_replace('/(\d+\s\=\s)(\d+)/ie', 'incDate($1,$2)',
$oldDate);
file_put_contents($file, $newDate . \n);
This works with one file but with multi lines I'm having trouble:
if the file has:
20060301 = 34
20060302 = 3
the file after script will be:
20060302 = 4
I want it to preserve the previous lines
so output should be:
20060301 = 34
20060302 = 4
Help would be great, thanks
Ben
