Hello,

In a MySQL table field, I have ; (semi-colon) in it. When I retrieve the data in a PHP script, I get premature termination of the script because of the ; (semi-colon)


Example of table field:
"The quick brown fox jumps over the lazy dog; so does the elephant"
(semi-colon after dog)


Example of PHP script:

...
$result = mysql_query($query);
while ($row = mysql_fetch_assoc($result)) {
extract($row);
echo "$contents";
}


What do I do?

why do you extract? it is unsafe

why dont you try this
$result = mysql_query($query);
while ($row = mysql_fetch_assoc($result)) {
//extract($row);
echo "$row->contents";
}

Gingera: the extract() command is not likely to be the problem.  See here:
http://us2.php.net/manual/en/function.extract.php

The data may not be getting stored in the data base in the first place!  It could be an escaping error.

Do you have phpMyAdmin?  If so, look at the data tables to see what is there.

Look at mysql_real_escape_string().  It will help keep the contents clean.
http://us2.php.net/manual/en/function.mysql-real-escape-string.php

You might also want to purify your character set on the in-bound side of the data base.  See code snippet.  HTH, ~Ray
function get_clean_text_string($string) 

{ // FORCE IT TO DB-ACCEPTABLE ESCAPABLE CHARACTERS ONLY

	$new	= trim(ereg_replace('[^\' a-zA-Z0-9&!#$%()"+:?/@,_\.\-]', '', $string));

	$new	= ereg_replace(' +', ' ', $new);

return ( $new );

}

replace your code with this
$result = mysql_query($query);

while ($row = mysql_fetch_assoc($result)) {

echo ereg_replace(';', '', $row['contents']);

}

Gingera: Any news to report?

@ayus80: ereg is a little slow in PHP.  For a single character better performance is available from str_replace().

Best, ~Ray
$result = mysql_query($query);

while ($row = mysql_fetch_assoc($result)) {

    echo str_replace(';', '', $row['contents']);

}
