<?php
function generatePassword($intNumOfChars) {
    if (is_numeric($intNumOfChars) && ($intNumOfChars > 0)) {
	$strChars = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_";
	for ($i = 0; $i < $intNumOfChars; $i ++)  {
	    $strPassword .= $strChars[rand(0, strlen($strChars)-1)];
	 }
    }
    return $strPassword;
}
?>

This is a function I use to display the ellipses when I want to truncate and display a summary of a larger body of text.

<?php
function truncateString($intLength = 0, $strText = "") {
    if ($intLength == 0) {
        return $strText;
    }
    if(strlen($strText) > $intLength) {
        preg_match("/[a-zA-Z0-9]{0, " . $intLength . "}/", $strText, $strNewText);
        return ($strNewText . "...");
    }
    else {
        return $strText;
    }
}
?>
