My script will fail if the amount of words in $MyOriginalString is less
than $MaxWords. So, this is the new suggestion:
<?php
$MyOriginalString = "This is my original string.\nWhat do you think
about this script?";
$MaxWords = 50; // How many words are needed?
$replacement = ereg_replace
("^([[:space:]]*[^[:space:][:cntrl:]]+){1,$MaxWords}",
"",$MyOriginalString);
echo substr( $MyOriginalString, 0, ($replacement) ?
-strlen($replacement) : strlen($MyOriginalString));
?>
Four lines.
BTW: Did I mention that I was forgetful? ;-)
Best regards,
Gustavo Narea.

Hello.
What do you think about this:
<?php
$MyOriginalString = "This is my original string.\nWhat do you think
about this script?";
$MaxWords = 6; // How many words are needed?
echo substr( $MyOriginalString, 0, -strlen(ereg_replace
("^([[:space:]]*[^[:space:][:cntrl:]]+){1,$MaxWords}",
"",$MyOriginalString)));
?>
Only 3 lines.
You have to change $MaxWords to 50 if that's what you need.

Hi,
I need to extract 50 words more or less from a description field. How
can i
do that?. Substr, cuts the words. Is there any other way to that, without
using and array? I mean and implemented function in PHP 4.x
I´ve been googling around, but wordwrap, and substr is driving me mad...
Thanks in advance
Best Regards
