- Searching and Replacing Character Entities

a database and then exporting that data into an XML format to redender
in flash using CDATA. The problem is that I didn't realize that Flash
has a problem with character entities such as ' ” and a few
others. I need to search and replace these but I keep on getting a SQL
I get this error:::
Query failed: You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to
use near 's Web site and landing...', content = 'Check customer's Web
site and' at line 3
My update SQL command is simple:
SET content = 'the new content to be inserted'
WHERE id = '22'
My PHP config on the server is (i just thought to take a look at how
the server was set up):
magic_quotes_gpc = on
magic_quotes_runtime = off
magic_quotes_sybase = off
I echo'ed out the query and I still can't see the problem. The only
thing that I can think of is that the content has " in it and I'm doing
a search and replace on it's character entity ” to change it to
the literal " but it ends up escaping those " to \" and it might end up
causing a problem in SQL. But see that sounds stupid to me so I'm not
too confident with that reasoning.
Here's the code in context as to what I'm doing currently
$newContent = str_replace($_POST['frmOldPhrase'],
$_POST['frmNewPhrase'], $srRow['content'], $contentCount);
$newTitle = str_replace($_POST['frmOldPhrase'], $_POST['frmNewPhrase'],
$sqlUpdateFields = '';
if( $contentCount > 0 )
$sqlUpdateFields .= "content = '".$newContent."'";
if( $sqlUpdateFields != '' )
$sqlUpdateFields .= ", ";
if( $titleCount > 0 )
$sqlUpdateFields .= "title = '".$newTitle."'";
$srUpdateSql = "UPDATE ".$table." SET ".$sqlUpdateFields." WHERE id =
That's the code I'm using. I'm stumped here. I tried addslashes()
around my content and that just added like 4 slashes because it was
escaping the already added slashes from having majic quotes on.
What am I doing wrong here??
Re: Searching and Replacing Character Entities
First of all, you should use mysql_real_escape_string() instead of
addslashes() to prepare your statement for inserting.
Then echo your statement before you insert it and post the entire output
of the echo (not some dummy data - it's important) here.
P.S. - is your id a numeric field? If so, you should not have quotes
around '22'. But that isn't where the message is pointing. You have
