Hi Guys ,
I have a vriable contain text with html tags
I want to cut the first 200 character from this variable without counting html tags .
What is the best method to do that ?

I suggest the folwing method :
1- move the text to another variable with strip_tags function .
2- get the first 200 character from new variable and put it in $mirror_var .
3- find the last word in $mirror_var .
4- get the the characters from main variable upto lastword .

But I have a problem in finding last word in $mirror_var
I want to know what is the best method to find last word in variable contain long text ?
OR
if there is another method better than my method

Cheers

to get the last word (untested)

PHP Code:

$mirror_array = explode(' ', $mirror_var);

$mirror_num = count($mirror_array);

$n = mirror_num -1;

$lastword = $mirror_array[$n]; 

dont know how fast this is but it should give you the last word (assuming words are separated with space (' '))
hope it helps

Set up the whole text as a var ie $text then:

PHP Code:

$data = explode(' ', $text);

$data_c = count($data);

$last_word = $data[$data_c];

echo($last_word); //or what ever you want to do with the last word 

Well hope that works...

Did you mean:

PHP Code:

preg_match("/(?<=\040)([\w\._-]*?)$/",$text,$matches);

echo $matches[0];

Thanks all guys

I tried all methods and found :

<?Wille?> : your method is good but it will fail in some cases

Eclipse : I think we must decrement $data_c to make it work .

mikaelf : your method didn't work may be I didn't understand it .

I found a good method which is :

PHP Code:

$txt='your text with words'; 
$out=preg_split('/\s+/',trim($txt)); 
echo $out[count($out)-1]; 

and it will work in all cases .

Yea i found that out and was going to post that now but I saw that you got it.

Hi GS300,
The regex I wrote should run if you test in in normal condition. If you want a faster regex which can satisfy all condition you can give a try to this one:

PHP Code:

$txt="your text with words. try to find the last word using several spaces before the last word    gsvdfg5412f_tw4t=agast3)(@35.\n";

preg_match("/(?<=\040)([^\s]+?)$/",trim($txt),$matches);

echo $matches[0]; 

How the above code works:
1. It will assert for a single space from the end of the string.
2. The word after the space is the last word. (simple enough, huh?)
3. It will yield only 1 match.

Comparation with your preg_split (how it works):
1. It will explode the string by empty spaces (space, tab)
2. It will yield an array with n elements.
3. The last word is the (n-1)th element of the array.

Using preg_match, you can save several "precious" microsecond and less memory consumption. Anyway, it's worth nothing compared to whole system.
