[PHP] string function that adds before and after
What I'm trying to do is find a substring in a much longer string and insert another string before and after the substring. For example: string to find: weather string to search in: This is the worst weather ever. Weather around here is terrible. string to add before: strong string to add after: /strong I can't do a simple search and replace, because I need to maintain the case sensitivity of the word that's in the searched string. So I was hoping to find something that would locate the string to find, add something before and after it (which that something before and after could be different from each other), then continue the search to see if another instance exists. And so on and so forth There's a number of functions in PHP that will give me the position of the *first* instance of the matched string, but it doesn't look like the function would keep searching after the first match. Anyway, am I overlooking a function that already has the functionality that I'm searching for? Or does anyone have any ideas how I can accomplish this efficiently since my search strings can be quite long?

try this
preg_replace('/(weather)/i', strong$1/strong, 'This is the worst
weather ever. Weather around

Thanks Matt. I think that will do the trick. Let me see if I
understand it correctly. the i will make the search case-INsensitive,
and the parenthesis around weather will store what it finds in the
variable $1? Is that right?
Thanks again, that was a big help.

Also consider str_replace() as it's faster albeit case
sensitive. str_ireplace() exists in PHP 5. Just another
option, I'm surprised you didn't find it when looking
around strpos() and friends.
Your assumptions above are correct, sorry Matt for stepping
in! :) I prefer cold weather.

Thanks Philip. I did notice str_replace() but it didn't look like I
could use it without it actually replacing what it found instead of just
adding strings before and after it. Am I wrong?

I'd say it will do the job just fine if case sensitivity is not an
issue:
$word = 'weather';
$new = str_replace($word, strong$word/strong, $phrase);
... speaks for itself ;)

I'm thinking to myself at this moment...
style
weather { font-weight: bold }
/style
It simply just would make the world a whole lot nicer :)
Do note, this is not a valid css tag, just a simple dream of mine.

First, let me assure you that this is not one of those shady pyramid schemes
you've been hearing about. No, sir. Our model is the trapezoid!

[PHP] string function that inserts a char
I just finished looking through string functions http://us2.php.net/manual/en/ref.strings.php and can't find one that inserts a character, not replaces one. If there's a string that's over 50 chars long without a space, I want to insert a space without replacing or losing any of the original characters. Is there a function to do that? advance thanks, Dale -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] About php String function
Hello, I am using strpos function for finding the string position in a particular string .If the string value is equal to zero or greater than zero some steps to be executed. If the position is empty it is taking as zero value and executing the steps under equal to zero loop..Is there any method avoid doing that ??

You need to use
if ($pos !== false) {
//pos found
}

The online manual for strpos() documents this:
http://www.php.net/manual/en/function.strpos.php
$mystring = 'abc';
$findme = 'a';
$pos = strpos($mystring, $findme);
// Note our use of ===. Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
echo The string '$findme' was not found in the string '$mystring';
} else {
echo The string '$findme' was found in the string '$mystring';
echo and exists at position $pos;
}

You can use strstr: if (strstr ($str, '.')) echo 'Full stop'; else echo 'No full stop'; Marco -- php|architect - The magazine for PHP Professionals The first monthly worldwide magazine dedicated to PHP programmers On Thu, 2002-11-28 at 08:49, Shaun wrote: Hi, Please can someone tell me how i can tell if a string contains a full stop? thanks -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
