parsing string in PHP

hi all,

how can I 'cut off' string in PHP?
for example:
I have a field in dbase smth TEXT , and fill it with some text... like "This is a text, blah, blah" (of couse real text is much larger).
now, how can I create a "preview" of that so when I display result of query it shows only first few words: This is a ..... .

what i figured out is this:

PHP Code:

---

$strDisplay = $row[text];
$strParse = $strDisplay{0} . $strDisplay{1} . $strDisplay{2}; 


---

which is not an option.... I'd like, say, first 20 chars to be displayed...
but how can I do like in c++ : $strParse = $strDisplay.Left(20) to take first 20 chars from left.....

TIA,
boris

You could use the substr function. Ideally, you would add the ... only if the length were less than the maximum.

yes, i tried

PHP Code:

---

$strDisplay = $row[text];
$strParse = substr($strDisplay,0,250) . "..."; 


---

...and it works like charm....

thx a lot
