Help with PREG_REPLACE and leaving delimeters.

TheGam

I basically am reading a HTML file into a variable and then just trying to find snippets of code and replace them with other HTML.

I use $replace = preg_replace($search, $replace, $match)

There is nothing special about the search field, I'd just type {title} if thats what I was looking for there are no special chars to do the clever matching :-) I'm guessing this is the problem.

However it does replace the word title with my HTML and but leaves the HTML surrounded by the {}. Why doesn't it remove them, if I just try a word with no punctuation, i./e xxxtitlexxx it moans for not having them.

I am new to all this, so any help is greatly appreciated.

Thanks

// Use str_replace() if possible.  It's faster.

// For preg_replace, try
$var= 'title';
$search= "/\{$var\}/"
print "debug: [$search]\n";

// The {..}  has a special meaning when it encloses a variable.
// Compare this:
$var= 'title';
$search= "/{$var}/"
print "debug: [$search]\n";

// Quick explanation: {} allows you to write things like this:
print "{$var}iable\n";
// Compare:
print "$variable\n";

Without seeing what $search or $replace are it's anyone's guess - mine would be that your regexp doesn't have any delimiters, so the {} are being used instead.

But for what you're doing I think preg_replace() sounds like overkill, and that [man]str_replace[/man] or [man]strtr[/man] would be quite adequate and a lot faster.

Edit: What he said. But note that {...} also has a special meaning in regexps.

Thanks Weed.

str_replace indeed looks a much better option :-) I';ll try that tonight, hadn'ty stumbled accross that one yet looking for commands to work on strings with :-)

Thanks!!!

Thanks also Kitchin for suggesting the same and also helping me with preg_replace, much appreciated to all.

Cheers!!
