PHP - Md5 Versus Plain Texst?

I understand that I can place my HTML code outisde of my PHP tags and have it publish, OR i can put it inside the PHP tags and ECHO every line.

Am I correct in thinking that either will provide the same result?

Is there an advantage to one method over the other??

I initially set up a few VAR items to learn some JS coding.   Then it became apparent that altering the group and entering them into an array would be more effective.   However, my limited knowledge is confusing the situation.   Is there a simple comparison (with proper code and formatting) that someone can provide?   Example:  student in the school info desired: name, age, hair color, eye color   As separate VAR listings I cannot sort by age, so I create an array, but how can I name them student 1, 2, 3 etc.  (or do I not want to??).

Is there anything different between a response and a responder?  My thought is maybe a response is something that one application gives to another, and a responder is used only by a single application to create a response.

interface TrendInterface
{
    public function getResponse($blabla):TrendResponse;
    public function getResponder($blabla):TrendResponder;
}

 

When sending data via $_POST for example, I've seen the data get filtered with both mysql_real_escape_string or htmlspecialchars

When should you use one or the other?

I launched my new website about a month ago.  I switched from one web host to another due to poor hosting performance.  Now I'm running into the same issue again -- poor web hosting performance.   My first web host was Hostgator.  My current web host is AT&T.  I hate the thought of switching to a different web host every month trying to find one that will reliably host my site.  Does anyone here have a reliable web host that they use and would recommend?   My question is relative since what is reliable for a simple web site, may not be reliable for one that is more complex.  For this reason, I can't simply trust web host reviews.   My website isn't overly complicated, but it's more complex than just basic HTML.  It uses a lot of PHP, as well as a MySQL database that only has two small tables.  The website uploads and downloads small text files regularly.  It also sends E-mail attatchments quite often.   Because I just launched, my website isn't getting a ton of traffic -- about 10 users per day.  However, I'm beginning to run into the same problem as before.  My web host's server is starting to show itself as being unreliable.  As with my first web host, it seems as if it may be due to overcrowding on the shared server.   Do any of you run any moderately complex websites?  If so, who do you use for a reliable web host?   I've considered setting up my own server with a LAMP configuration and hosting the site myself.  However, I don't know a lot about Linux or Apache, and so would like to avoid this.  But because the computer would only be hosting my own website, and no one else's, I have to believe that a LAMP setup would be more reliable than a shared server that is overcrowded.   A reliable web host is really what I'm looking for.  But I don't want to keep going down the road of trial and error.  If anyone uses a web host that reliably supports their moderately-complex website, then I would love to hear from you.  I'm sick of my site failing due to server issues.  Like the Duracel commercial says, "It just has to work!"   Please forgive me if you feel that my post doesn't correctly fit the forum category.  I tried to figure out which category best fits this topic, but none of them seemed to be perfectly suitable.   Thank you for your time, as well as for any suggestions.

Hi, I found a tutorial online for a form which used PHP/MySQL and JQuery to submit data. I am making some modifications and the form no-longer submits the data. The problem I have is no errors display so I am not sure where the problem lies. I need to be able to display a success or failure message on the form itself, but this is either not there or not working. The code is below.

Code: [Select]
<form id="ContactForm" action="">
                <p>
                    <label>First Name</label>
                    <input id="FirstName" name="FirstName" class="inplaceError" maxlength="120" type="text" autocomplete="off"/>
<span class="error" style="display:none;"></span>
                </p>
                <p>
                    <label>Last Name</label>
                    <input id="LastName" name="LastName" class="inplaceError" maxlength="120" type="text" autocomplete="off"/>
<span class="error" style="display:none;"></span>
                </p>
                <p>
                    <label>User Name</label>
                    <input id="UserName" name="UserName" class="inplaceError" maxlength="120" type="text" autocomplete="off"/>
<span class="error" style="display:none;"></span>
                </p>
                <p>
                    <label>Email</label>
                    <input id="email" name="email" class="inplaceError" maxlength="120" type="text" autocomplete="off"/>
<span class="error" style="display:none;"></span>
                </p>
                <p>
                    <label>Website<span>(optional)</span></label>
                    <input id="website" name="website" class="inplaceError" maxlength="120" type="text" autocomplete="off"/>
                </p>
                <p>
                    <label>Your message<br /> <span>300 characters allowed</span></label>
                    <textarea id="message" name="message" class="inplaceError" cols="6" rows="5" autocomplete="off"></textarea>
<span class="error" style="display:none;"></span>
                </p>
                <p class="submit">
                    <input id="send" type="button" value="Submit"/>
                    <span id="loader" class="loader" style="display:none;"></span>
<span id="success_message" class="success"></span>
                </p>
<input id="newcontact" name="newcontact" type="hidden" value="1"></input>
            </form>

and the JQuery

}
else 
return true; 
});
},
ContactFormSubmit : function() {
$.ajax({
   type : 'POST',
   url : 'php/contact.php?ts='+new Date().getTime(),
   dataType : 'json',
   data : $('#ContactForm').serialize(),
   success : function(data,textStatus){
  //hide the ajax loader
  $('#loader').hide();
  if(data.result == '1'){
      //show success message
  $('#success_message').empty().html('Message sent');
  //reset all form fields
  $('#ContactForm')[0].reset();
  //envelope animation
  $('#envelope').stop().show().animate({'marginTop':'-175px','marginLeft':'-246px','width':'492px','height':'350px','opacity':'0'},function(){

  else if(data.result == '-1'){

          $("#"+data.errors[i].name).next().html('<span>'+data.errors[i].value+'</span>').fadeIn();
  }
  }  
  },
   error : function(data,textStatus){}
});
} 
};

I know that magic __get and __set are invoked automatically when an object is instantiated, but what about stuff like getName() and setName()

Code: [Select]
class NameClass {
private $_name;
public function getName() {
return $this->_name;
    }
public function setName($value) {
$this->_name = $value;
    }
}

$someName = new NameClass();
$someName->setName('Bob');
echo $someName->getName();
1. Could the setName() and getName() just as easily be named something generic like:

hotName()
coldName()

Code: [Select]
class NameClass {
private $_name;
public function hotName() {
return $this->_name;
    }
public function coldName($value) {
$this->_name = $value;
    }
}

$someName = new NameClass();
$someName->coldName('Bob');
echo $someName->hotName();
2. Also, the setName() and getName() methods must be called manually, right? Unless they are manually called, they just sit there, do nothing, am I correct?

Thanks

good day dear community,


this is a big issue. I have to decide: between native PHP DOM Extension or of simple DOM html parser

well i want to parse the site he http://buergerstiftungen.de/cps/rde/xchg/SID-A7DCD0D1-702CE0FA/buergerstiftungen/hs.xsl/db.htm

http://buergerstiftungen.de/cps/rde/xchg/SID-A7DCD0D1-702CE0FA/buergerstiftungen/hs.xsl/db.htm

I will suggest to use the native PHP "DOM" Extension instead of "simple html parser", since it will be much faster and easier

What do you think about this one here...:

Code: [Select]
$doc = new DOMDocument
@$doc->loadHTMLFile('...URL....'); // Using the @ operator to hide parse errors
$contents = $doc->getElementById('content')->nodeValue; // Text contents of #content


look  forward to hear from you

best regards

How can I make index.php?view=cart work in place of cart.php in the following code?
Works:
header("Location: cart.php?msg=Thank you. Check your e-mail for Login details.");
die;
} else header("Location: cart.php?msg=Account with given email does not exist.");
die;
Doesn't work:
header("Location: index.php?view=cart?msg=Thank you. Check your e-mail for Login details.");
die;
} else header("Location: index.php?view=cart?msg=Account with given email does not exist.");
die;

i'm running code on what i only want to be the HOME page, but the current site it built using GET variables with index.php

needless to say, the home page is accessed either as domain.com/ or domain.com/index.php - i'm hoping someone can show me how to check for this condition, that it is only index.php without anything further

I'm only slightly familiar with $_SERVER['uri'], etc... So i don't know just what to ask.

thanks for anyone's help.
