    copied!<p>Within a function on my parent file, I am calling a function from an external php file. Here is my (simplified) code:</p> <p>Parent file:</p> <pre><code>include "HelperFiles/htmlify.php"; function funcName(){ $description = "some sample text"; $description = htmlify($description, "code"); echo $description; }; funcName(); </code></pre> <p>htmlify.php file with called function:</p> <pre><code>$text = ""; function htmlify($text, $format){ if (is_array($_POST)) { $html = ($_POST['text']); } else { $html = $text; }; $html = str_replace("‘", "'", $html); //Stripping out stubborn MSWord curly quotes $html = str_replace("’", "'", $html); $html = str_replace("”", '"', $html); $html = str_replace("“", '"', $html); $html = str_replace("–", "-", $html); $html = str_replace("…", "...", $html); if ($format == "code"){ $html = str_replace(chr(149), "&amp;bull;",$html); $html = str_replace(chr(150), "&amp;mdash;",$html); $html = str_replace(chr(151), "&amp;mdash;",$html); $html = str_replace(chr(153), "&amp;trade;",$html); $html = str_replace(chr(169), "&amp;copy;",$html); $html = str_replace(chr(174), "&amp;reg;",$html); $trans = get_html_translation_table(HTML_ENTITIES); $html = strtr($html, $trans); $html = nl2br($html); $html = str_replace("&lt;br /&gt;", "&lt;br&gt;",$html); $html = preg_replace ( "/(\s*&lt;br&gt;)/", "\n&lt;br&gt;", $html ); // seperate lines for each &lt;br&gt; //$text = str_replace ( "&amp;amp;#", "&amp;#", $text ); //return htmlspecialchars(stripslashes($text), ENT_QUOTES, "UTF-8"); return htmlspecialchars($html, ENT_QUOTES, "UTF-8"); } else if ($format == "clean"){ return $html; } }; </code></pre> <p>I'm getting the following error:</p> <p>Notice: Undefined index: text in C:_Localhost_Tools\HelperFiles\htmlify.php on line 25</p> <p>I've tried declaring the $text variable inside and outside of scope in multiple places but can not seem to get around this error (warning). Any help would be greatly appreciated! Thanks.</p>
