PHP - ? Character In Link

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?

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 

All,
I have a zip code and for example the zip code is 01101. How can I determine if the first character in this is a zero?

Thanks in advance.

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 \' . -)';
}
}


Debbie

so if I have a a string of text or something like

Code: [Select]
http://www.yahoo.com/ajhsijd908340

I can use str_replace to remove "http://" but what can I use to remove the "ajhsijd908340" if every time it is a different set of characters?

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

Im bug fixing a script (not my own) and the use of   "  and  '   hasn't been filtered out before an insert query is ran.

there are about 4 scripts of 30 $_POST["something"] input elements that need to be checked, and i was wondering can i just do a find and replace on $_POST rather than each element?

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

<form action="main.php?id=test.php" method="post">
<input name="name" type="text" />
<input name="submit" type="submit" value="Look Up" />
</form>
<?php
if(isset($_POST['submit'])) {
$today = date("Y-m-d");
$pname = rawurlencode($_POST['name']);
$xml_feed_url = 'http://api.eve-online.com/eve/CharacterID.xml.aspx?names='.$pname.'';

The above works perfect until the user enters a character like ' to the box, how do I get it to pass the ' into the address?

Thank you
