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.
