  1. Q: Should instancing an object be held off until needed - or - instanced early and held in memory until (it may/or may not) be called? Here is an example of the type situation where an custom error reporting class is instanced only when some test has failed. The error reporting is for authorized users running an application from protected sub sections(RESTish solution). /* * check form input and $_FILES upload * if test fails, instance errorwrapper::factory object and call errorReport method * testfilesize function, compares file size limit, set pass1 to true on success * testfiletype function, compares file to allowed MIME types, set pass2 to true on success * svalidate returns array $filteres, sanitized input on success, error message(s) on fail * param boolean $pass[1,2], set initial test condition * param int MAX_FILE_SIZE, constant defines max file size allowed. */ $pass1 = false; $pass2 = false; if(isset($_FILES)) { $ftype = $_FILES['img_file']['type']; $fsize = $_FILES['img_file']['size']; testfilesize($pass1,MAX_FILE_SIZE,$fsize); testfiletype($pass2,$ftype); } if($pass1 == false) { $erparams=array('cat'=>3,'src'=>"addform_control",'ref'=>"addform",'fault'=>"over file size limit"); $errObj=errorwrapper::factory($erparams); $errObj->errorReport(); exit(); } elseif ($pass2 == false) { $erparams=array('cat'=>3,'src'=>"addform_control",'ref'=>"addform",'fault'=>"illegal file type"); $errObj=errorwrapper::factory($erparams); $errObj->errorReport(); exit(); } /* * process form input, all fields checked before returning filteres * could report multiple errors, mode sets level of sanitization. */ $filteres = svalidate($_POST,$mode=1); if($filteres['exit']==1) { foreach($filteres['err'] as $err) { $mes .= $err."\n"; } $erparams=array('cat'=>2,'src'=>"addfo",'ref'=>"list_viewer",'fault'=>$mes); $errObj=errorwrapper::factory($erparams); $errObj->errorReport(); exit(); } else { //continue processing here, error checking over } In this case, the object $errObj is only instanced on a failed condition. However, $errObj could be instantiated before the conditional test and only calls the method when there is a failed condition. It seems like "six to one half dozen" but these applications are large and complex, so I'm looking to squeeze out any worthwhile optimization. Thanks for considering the question.
  2. Hi Guys, I just write the code in php but mail function is not working rest everything is working fine.. i tried other script but that also not working.. Than i came to know that my hosting server only use SMTP.. So i need help to do that..

" name=\"{$value}\"\n" . "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n" . "--{$mimeBoundary}--\n"; } $userimg=implode(',',$img); } $sql="insert into treatment_mail(comment_name,email,contactno,message,page_id,report1,mail_date)values('".$fromName."','".$fromEmail."','".$subject."','".$message1."','".$c."','".$userimg."','".time()."')"; mysql_query($sql); $flgchk = mail ("$to", "$subject", "$message", "$headers"); /* this code is not working*/ if($flgchk){ echo $msg="A email has been sent to: $to"; } else{ echo $msg= "Error in Email sending"; } return $msg; } } $obj_mail=new patient_mail(); ?>
