PHP - Special Characters

Code: [Select]
<?php>
$filename='http://www.example.com/polopoly_fs/1.1034350!/img/httpImage/image.jpg';
$size = getimagesize($filename);
print $size;
</php>

If the image has symbol "!", it takes long time to execute the script. Please tell me how can we avoid this.

Am trying to save a text input that require the use of some php special characters like (" ", ' ' ) e.t.c. When ever i post the data, the system returns an error. please, how can i go about this?   Thanks in advance

Code: [Select]
$DB->query("SELECT id,name from ibf_members where name = '{$ibforums->input['to']}' LIMIT 1");
       $e2 = $DB->fetch_row();
   if ($e2['id']){
   }else{
   $std->Error2("Username doesn't exist dude");
   }

Ok, if I put in my username let's say

1of my users name is

"$tabB"

if I do that, it doesn't work

is there a work around?

I hope this is a fairly quick one, I've got a form I'm building where i may well have some special characters being inserted (accents mostly) now normally i would just pop in an HTML editor (TinyMCE) and let that deal with it. But i am looking to export this data as a CSV for use in excel, which means i can't afford to have HTML tags within the output.

I am sure someone will have come across this before any suggestions?

many thanks

Hi all,


I've been running a basic contact us form using a textarea for users to send us enquiries for a few months now. We have a few foreign users that use special accented characters like umlaut etc... Which are common to lots of languages other than english. When the php script processes the data and sends it in a html based email it screws up the symbols and sends a load of rubbish where they should be.

I have been trying out a few variations of script but cannot get any to display correctly.

Old script:

function previous_request_value($str) {
if (isset($_REQUEST[$str]) )
return $_REQUEST[$str];
else
return '';
}

function cndstrips($str) {
if (get_magic_quotes_gpc())
return stripslashes($str);
else
return $str;
}

$visitor_email=cndstrips(trim(previous_request_value('visitor_email')));
$visitor_name=cndstrips(trim(previous_request_value('visitor_name')));
$visitor_companyname=cndstrips(trim(previous_request_value('visitor_companyname')));
$message_body=cndstrips(trim(previous_request_value('message_body')));
$message_telephone=cndstrips(trim(previous_request_value('message_telephone')));
$msg_subject=cndstrips(trim(previous_request_value('msg_subject')));


Current Version (My attempt at editing the code to convert specialchars still doesnt work correctly):


function previous_request_value($str) {
if (isset($_REQUEST[$str]) )
return $_REQUEST[$str];
else
return '';
}

function cndstrips($str) {
if (get_magic_quotes_gpc()) {                           
$str = htmlspecialchars(stripslashes($str), ENT_QUOTES);
} else {
$str = htmlspecialchars($str, ENT_QUOTES);
}
preg_replace('/&(?![A-Za-z0-9#]{1,7};)/','&amp;',$str);
return $str;
}

$visitor_email=cndstrips(trim(previous_request_value('visitor_email')));
$visitor_name=cndstrips(trim(previous_request_value('visitor_name')));
$visitor_companyname=cndstrips(trim(previous_request_value('visitor_companyname')));
$message_body=cndstrips(trim(previous_request_value('message_body')));
$message_telephone=cndstrips(trim(previous_request_value('message_telephone')));
$msg_subject=cndstrips(trim(previous_request_value('msg_subject')));


Any ideas where i'm going wrong?

Plus another slightly annoying feature is if a user enters html entities as &amp; instead of just &, it double encodes it to &amp;amp; I have tried to use htmlspecialchars_decode first but it crashes the whole script.

I'd appreciate any help available. Thanks.

When our members try to insert text from other sources, some of the markup gets transformed into special characters. We think this is caused by the transition from rich text editors to our text areas. Any idea how to fix this?

So I've slowly noticed that thinks like apostrophes and such will cause mySQL queries to fail when going through PHP? I believe it probably has something to do with escaping and magic quotes? For instance, see this code:

Code: [Select]
$ename = "Jakes";

$qry = "SELECT * FROM userBars WHERE barName='$ename'";
$result = mysql_query($qry);

if($result){
echo "success";
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
    echo "Name :{$row['barName']} <br>" .
          "ID : {$row['barID']} <br>" .
          "Address : {$row['barAddress']} <br><br>";
}
}else{
echo "Error";
}
That work fine, but say it's spelled "Jake's" in the database, that appears to fail every time. It's got to be something PHP is doing because if i just query the database like so:

SELECT * FROM userBars WHERE barName="Rick's"

from database console, it works just fine and I see the entire row. Anyone have any clue what's going on here?

I created a form where someone can add their name and a comment and then submit it to my database.
here's the code of the form

Hey guys,

So when I put the following line of php on an html page:
Code: [Select]
echo '&reg';

I get the 'Registered' symbol. How do I turn this off? What is happening is that it is part of a longer string that represents an url and the URL is not rendering correctly due to the special character.

Thanks
