PHP - Character Problems

Thanks to the advice of others on PHPFreaks, I have decided that allowing any character for certain fields on my "Add an Article" form.  However, I still want to define a length between 2 and 100.

How do I re-write my RegEx to accomplish this?

Befo
Code: [Select]
// Check HTML Title.
if (empty($trimmed['htmlTitle'])){
$errors['htmlTitle'] = 'Please enter an HTML Title.';
}else{
if (preg_match('#^[A-Z \'.-]{2,100}$#i', $trimmed['htmlTitle'])){
$htmlTitle = $trimmed['htmlTitle'];
}else{
$errors['htmlTitle'] = 'HTML Title must be 2-100 characters (A-Z \' . -)';
}
}


Here is my best guess...

After:
Code: [Select]
// Check HTML Title.
if (empty($trimmed['htmlTitle'])){
$errors['htmlTitle'] = 'Please enter an HTML Title.';
}else{
if (preg_match('#^[.*]{2,100}$#i', $trimmed['htmlTitle'])){
$htmlTitle = $trimmed['htmlTitle'];
}else{
$errors['htmlTitle'] = 'HTML Title must be 2-100 characters (A-Z \' . -)';
}
}

Hey,

I'm having an issue with using Wikipedia's OpenSearch API - it sometimes gives me characters in a unicode format: "\u00f1" and I would like to convert back into a correctly displayed format (in this case, n-tilde; spanish n).

Any suggestions?

I got another problem. It is a counting characters.
When I reload text from database, I want to count how many characters are in text. The problem is that I use the timymce, and there is a tags </p> and formats <span> and other formats. How can I count characters without those format, just pure characters entire text? I need a php code. And some plus - text is in utf8 coding in database with utf8 bin.

I have problem, there are users with "?" character in username, and their address to profile is /profile/username/.
I have var: $username that is that username, now, how can i replace all that characters which cant open users profile..
I mean for "?" i need to put "%3F", how can i replace?
I know with str_replace, but is there any other solution like htmlencode or something like that? :S

Hi, does anybody know why I get a question mark inside a diamond shape where a pound sign should be when i retrieve data from a mysql database? I have tried using latin1_general_ci and utf8_general_ci and they both do the same, don't know whether that is anything to do with it or not? Any help would be greatly appreciated.

all i want is for when their is a _ to be replaced with a space so i tried these and neither worked
Code: [Select]
<?php
$pmod = str_replace("_"," ",$p);
$pmod = preg_replace("_"," ",$p);
?>
so i was wondering if because this was in a while statement, is this the reason its not working, and if so how should i fix it (this is the while)
Code: [Select]
<?php
while ($z <= $w){
$p = $multi[$z];
        $pmod = str_replace("_"," ",$p);
echo "<a href='tag.php?tag=$p'" . $p . ">" . $pmod . "</a> ";
$z++;
}
?>

HI all, something that keeps bothering me is that i do not fully understand the usefullness of the \n newline character.
When i use  for testing in a string it doesn't show the effect in my browser. Only when I press view source I can see that right after the \n character the code jumps down 1 line. Does anyone know how and when to use it? I have see it with the php mail function, but i don't really understand why they use it.

If someone could enlighten me i would be very happy 

I am terribly confused... I am trying to display the html body of a message pulled through imap.

I thought that if I did this:
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />

in the html head, that everything would be pretty much figured out for me, but...

When I look at the original message in gmail (prior to being pulled with imap), I get an ellipses(...), but once I display it in my browser, I get a black diamond question mark thingy...

Help!  I've tried all manners of conversion, but suspect I'm completely missing the boat here.

Thanks

I would like to have a generator that basically creates a certain number of mixed characters.
For example 6 characters which use A and B
It would randomly produce things such as
ABAABA
BABABB

I cannot think of any basic ways of achieving this.
Any help would be appreciated even if its written rather than code.
Thank you in advance.

Hello everyone,

I have created a widget with php which allows users to put on their webpage and displays some information. To display the widget I am creating a javascript code for users to put on their websites.
The javascript has a source of php page like src="widget.php?id=123" When they put the code on their websites php file is executed and displays some texts which is read from a remote XML file. There is no problem up to this point. But while I am reading from this XML file, the texts which are displayed on users webpage, are not in good format becouse I am converting string texts to ISO_8859-9 charset with "iconc" function.

If the charset of webpage is ISO-8859-9 text are displayed correctly but if it is not, text are not displayed as expected.

In example if the webpage charset is set to UTF-8, characters become unreadable. If I know the charset of webpage I can then convert strings to that charset. But could not find a predifined function thats doing this.

Any idea about this problem ? or any other solutions you advice for this problem ?

Thank you...

How do you find out how many character within a String ??

for example:

$temp = "apple";

I want to return "5" for $temp as it has 5 characters. Thanks!

Array ( [0] => Virender Sehwag|||http://abc.xyz.com/Virender-Sehwag [1] => Sachin Tendulkar|||http://abc.xyz.com/Sachin-Tendulkar )


foreach($array as $arr) {

                $topics=explode ('|||', $array);


echo '<li>'
                        .'<a rel="nofollow" target="_new" href="'.$topics[1].'"><span class="title">'.html_entity_decode($topics[0], ENT_NOQUOTES, "UTF-8").'</span></a>|</li>';



How to avoid '|' for the last element of any aaray. Also if array contains only 1 element '|' should not appear.

For eample,

In the browser it should display as "Virender Sehwag | Sachin Tendulkar".

If the array contains only 1 element then, In the browser it should display as Virender Sehwag

if array contains 3 elements,

Virender Sehwag | Sachin Tendulkar | someword

I have this command that basically populates my website with titles for pages based on the information that is placed within "info.txt" I have multiple titles being created so I'd like a way of putting them in order beside alphabetically.

My thought was that I could place numbers as the first character in the "info.txt" file and that would allow me to put the titles in an order I find acceptable. Now this causes the issue that I don't want those numbers displayed on my website. So the Echo needs to strip the number.... I'm lost, but my brain thinks it's a good idea.

Here's the code I'm working with:

Code: [Select]
<tr>
<td id="body">
<table id="columns" cellspacing="0">
<tr>
<td>

<h2>LSAV Latest Events</h2>
<p>Select an event from below to view a gallery of images from that event.</p>
<ul>
<?php
$dir = 'latest-events';
if ($handle = opendir($dir)) {

    while (false !== ($file = readdir($handle))) {
if( $file != '.' && $file != '..') {
$title = file_get_contents( "$dir/$file/info.txt" );
echo "<li><a href=\"event-viewer.php?event=$file\">$title</a></li>";
}
    }
    closedir($handle);

Hey all,

I'm looking to produce a random 10 character string like: abcABC0123 when the below method is called:

<?php

function randomize(){
   $chars = explode(' ',(range("a","z"))) . explode(' ',(range("A","Z"))) . explode(' ',(range("0","9")));
   $pass = "";
   for($i = 0; $i < $len; $i += 1){
      array_push($pass,$chars[rand(count($chars)-1)]);
   }
   return $pass;
}

var_dump(randomize(10));

?>
But the randomize method is not returning desired result. Any idea what I'm doing wrong?

Thanks for response.
