Recently I had the job to convert EPS files to SVG graphics. It has been done for a product configurator that had to be implemented. The whole implementation mentioned here was done for a Magento Online Shop. But the base-paradigms described here can be used in other PHP based applications too because I’ve implemented them […]
<?php /** * * String helper class * */ abstract class Sheldon_Misc_String_Helper { /** * @param $sStr – String to clean * * @return string clean string * */ static function cleanWhitespaces( $sStr ) { if ( ! empty( $sStr ) ) { return preg_replace(‘/\s+/’, ”, $sStr ); } return $sStr; } /** * reverse […]
As a reverse function of nl2br you can use: <?php /** * reverse function for nl2br * @param $string – string with br’s * @return string – string with \n */ function br2nl($string) { return preg_replace(‘/\<br(\s*)?\/?\>/i’, “\n”, $string); } ?>
This little snippet tries to get the IP-Address of the user: private function _detectIP(){ //Mage::log(‘_detectIP’, null, __CLASS__.’.log’, true); if (getenv(‘HTTP_CLIENT_IP’)) { $this->_ip = getenv(‘HTTP_CLIENT_IP’); Mage::log(‘Detected IP (getenv(\’HTTP_CLIENT_IP\’)):’, null, __CLASS__.’.log’, true); Mage::log($this->_ip, null, __CLASS__.’.log’, true); } elseif (getenv(‘HTTP_X_FORWARDED_FOR’)) { $ips = explode(‘,’, getenv(‘HTTP_X_FORWARDED_FOR’)); $this->_ip = (string)trim($ips[0]); } elseif (getenv(‘HTTP_X_FORWARDED’)) { $ips = explode(‘,’, getenv(‘HTTP_X_FORWARDED’)); $this->_ip = […]
Hence nl2br does NOT really replace newlines with <br /> tags (it only inserts a <br /> tag before each \n → newlines themselves are preserved), you can use this function to get it right (realNl2Br): /** * @param $string – string with * @param bool $xhtml – deliver xhtml confom br’s or not (<br […]
