PHP - Php Character Coding

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++;
}
?>

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.

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?

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 \' . -)';
}
}

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 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

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 had a thread here recently titled: Special Language characters doesn't display correctly. Now however, I have encountered a new problem with character sets, that I hope you can help me resolve! I find the concept of character sets quite confusing. When you are dealing with a database and want the content to be displayed on a web page, you obviously want it to be displayed correctly, and if you are not from an English speaking country, this could cause you some problems here and there due to international characters. As I have understood, one need to tell how the data (text) is stores in the database, how it is being interpreted (collation) and how it is being displayed on the web page.   Here is my situation: One php page is displaying the content of a guestbook: show_content. This php file is divided into three parts: An include of a header.html file, a middle section displaying the content of the database and finally an include of a footer.html file to take care of the lower part of the page. Now, the header.html file does contain the script for a dropdown menu written in javascript:   header.html

<html>

<head>
  <title>Guestbook</title>
  <meta http-equiv="Content-Language" content="da">
  <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">

  <LINK REL=stylesheet TYPE="text/css" HREF="generel/pop_style.css">
  <LINK REL=stylesheet TYPE="text/css" HREF="generel/hoved.css">
</HEAD>

<BODY leftmargin=0 topmargin=0 marginwidth=0 marginheight=0 background="generel/univback.gif">

<script type="text/javascript" language="JavaScript1.2" src="generel/pop_core.js"></script>
<script type="text/javascript" language="JavaScript1.2" src="generel/pop_data.js"></script>
<script type="text/javascript" language="JavaScript1.2" src="generel/pop_events.js"></script>

<!--etc .......

The main page controlling this header:   show_content.php

<?php

function handle_fatal_errors() {
	if (http_response_code() == 500) {echo 'A technical error ocurred.';}
}

register_shutdown_function('handle_fatal_errors');	
ini_set('display_errors', 0);

include("header.html");
include("settings.php");
header('Content-Type: text/html; charset=utf-8');

//etc ...

The footer.html file doesn't really matter here, so I avoid it.   Now the strange thing: When I execute the show_content.php file above, the content of the database (guestbook) display perfectly, but the International letters in the dropdown menu don't display properly. BUT if I out-comment the following line:   

header('Content-Type: text/html; charset=utf-8');

in the show-content.php file it is the opposite way around!! Then the items in the dropdown menu display properly while the content of the guestbook don't!   By the way: When I connect to the database to store items, I do it with the following code:

$db = new PDO('mysql:host='.$server.';dbname='.$database.';charset=utf8mb4', $username, $password);

If somebody have an idea for an explanation of this behavior, I will be happy to hear about it! To me all these character set issues seem rather overwhelming. Maybe one setting override the other or what?   NB! I also read that the people around the developement of PHP temporarily gave up on Unicode support for a PHP 6.0 version ...   Erik

If I was pulling back data from MySQL that was like this "monkeys / dogs / cats", how would I grab just "monkeys" from that using PHP?

In other words, I want to grab all text until a "/" is seen.

i'm trying to an if statement so that a piece of code is only executed if a returned variable equals a letter in the alphabet(any letter)
the variable is from a $_GET, and all i want to check is if the variable contains a letter.
This is what i have so far, but it doesnt work


$sort=$_GET[orderby];
if ($sort=="[A-Z]") {
$read=mysql_query("SELECT * FROM films WHERE title LIKE '".$sort."%'") or die(mysql_error());
$result=mysql_num_rows($read);
}
else { 
$read=mysql_query("SELECT * FROM films ORDER BY title") or die("query failed");
$result=mysql_num_rows($read);
}


Any help would be great.

I need to pass info to a php script via link while ignoring the character '&' for example:
mywebsite.com/myphp.php?info=thisInformation&thecharacter&

is there anyway I can tell php to ignore the character '&' and just read it as text (cause
I understand its a special character..
maybe something like in XML you can ignore the character & by using <![CDATA[ ]]>

thanks!!! much appreciated!!!


PS: this is a must.. since in the end I am passing links.. and urls.. that are like amazon.com/blah&blah   

I have a $string with this structure "word-word2 something-SECONDPART". I want to divide it to $string1 and $string2 by separating with the last "-".

The point is that "-" exists in the first part, and I just want to make the second string after the last "-"

I am trying to find a character in the follwing string
$string = ' Mumbai Mast Kallander - 02 - Mumbai Mast Kallander';

the character i want to find is '-' and the find how many times does it occur in the string.. can anyone help?
