I have some code that's taking over 3 seconds to complete. I'm just wondering if there's a faster way to do this. I have a string with anywhere from 10 to 70 rows of data.
I break it up into an array and then loop through the array to find specific patterns.

            $this->_data = str_replace(chr(27)," ",$this->_data,$count);//strip out esc character
            $this->_data = explode("\r\n", $this->_data);

            $detailsArray = array();
            foreach ($this->_data as $details) {          

              $pattern = '/(\s+)([0-9a-z]*)(\s+)(100\/1000T|10|1000SX|\s+)(\s*)(\|)(\s+)(\w+)(\s+)(\w+)(\s+)(\w+)(\s+)(1000FDx|10HDx|100HDx|10FDx|100FDx|\s+)(\s*)(\w+)(\s*)(\w+|\s+)(\s*)(0)/i';             
              if (preg_match($pattern, $details, $matches)) {

                  array_push($detailsArray, array(
                    'Port' => $matches[2],
                    'Type' => $matches[4],
                    'Alert' => $matches[8],
                    'Enabled' => $matches[10],
                    'Status' => $matches[12],
                    'Mode' => $matches[14],
                    'MDIMode' => $matches[16],
                    'FlowCtrl' => $matches[18],
                    'BcastLimit' => $matches[20]));
                }//end if
            }//end for   
            $this->_data = $detailsArray;       

Just wondering if you think there's a way to make it more efficient. Thanks.
