[SOLVED] Replacing SMART quotes

[Petsmacker]

<?
$p=$_POST['p'];
if ($_POST['p']){
$p=str_replace("“", "\"", $p);
$p=str_replace("”", "\"", $p);
$p=str_replace("’", "'", $p);
$p=str_replace("‘", "'", $p);
$p=str_replace("–", "-", $p);
$p=str_replace("•", "-", $p);
}?>

<table width="100%"><tr><td class="left"><div id="gg"><?echo "$p";?></div></td></tr></table><br><br>
<form method="POST" name="ff">
<textarea style="width:60%;height:400px;" name="p"></textarea>
<br><input type="submit" value="Go">
</form>

 

My code is as simple as that but str_replace isn't changing them. Thats ALL the HTML and PHP on my page I've stripped away any other things that could cause it. Thats all on my page. Why aren't things changing?

because

if ($_POST['p'])

isn't ever true.

 

it should be

if (isset($_POST['p']) && !empty($_POST['p']))

 

but actually you should call that FIRST

if (isset($_POST['p']) && !empty($_POST['p'])){
$p=$_POST['p'];
$p=str_replace("“", "\"", $p);
$p=str_replace("”", "\"", $p);
$p=str_replace("’", "'", $p);
$p=str_replace("‘", "'", $p);
$p=str_replace("–", "-", $p);
$p=str_replace("•", "-", $p);
}?>

If I add:

$p=str_replace("a", "gfdgfgfdg", $p);

to it it works just fine.

 

Nonetheless, I tried adding your bit but no, it does nothing. The characters aren't replaced.

 

 

Letters, numbers and simple punctuation don't seem to be a problem for str_replace to work but I can't get it to with those characters.

What you are trying to do is replace "smart quotes" (dumb Microsoft quotes). Please read Convert Smart Quotes with PHP.
