changing to preg_match question

[futrose]

I have this bit of code that was originally ereg but needed changed to preg_match.  I'm just not sure where to put the delimiter in these two lines.

 

$ee[$i]=preg_match('-','/',$ee[$i]);

 

and

 

$es[$N]=preg_match('-','/',$es[$N]);

 

thanks.

I would recommend str_replace() since it doesn't require regular expressions:

thanks, I went with str_replace and it got rid of the errors.  I now have this line

 

$body=preg_replace("[date]",$showDateS,$body);

 

on the output it is placing the "[" and "]" around my date.  How do I make that go away?

if you have the [] as part of the text to find it shouldn't retain those characters when it is replaced. Show the part of the text that contains '[date]' as well as what the value of $showDateS is.

You're actually using preg_replace() which uses regular expressions. Basically, the square quotes in "[date]" are being used as the delimiter. So they're not technically part of the search.

 

Instead, try str_replace():

 

<?php
$body = str_replace("[date]", $showDateS, $body);
?>

ahhhh... nice.  Changing to str_replace took care of the the "[]" problem.  Thanks a lot.

No problem

 

 

For what it's worth, the regular expression would have needed to look something like the code below. The "/" character is the delimiter. Square brackets need to be escaped with "\" since they have special meaning in regular expressions.

 

<?php
$body = preg_replace("/\[date\]/", $showDateS, $body);
?>

 

 

Note: str_replace() is a better option in this case since it doesn't require the power of regular expressions.

I don't know what I was thinking. I followed the post about using str_replace() and totally blew it on recognizing that preg_replace() was being used. BUt, now that I think about it, the square brackets should not have worked as delimiters. The delimiter is supposed to be the same character. A left and right bracket are different characters. Odd.

Huh, good point.

Note quite. Brackets can also be used as delimiters, and then they do they're used in the open-close positions as they're named.

In addition to the aforementioned delimiters, it is also possible to use bracket style delimiters where the opening and closing brackets are the starting and ending delimiter, respectively.

{this is a pattern}
