Error on strings that contains “&” in XML. How can I fix this?

问题

I am using the following code to import my data from XML to mySQL. Is there any way to encode & before loading it using PHP instead of manually change it from the file?

this is the error

Warning: simplexml_load_file() [function.simplexml-load-file]: products.xml:4: parser error : xmlParseEntityRef: no name in ... on line 5

Warning: simplexml_load_file() [function.simplexml-load-file]: <description> DAYLIGHT & LED / SMD Tech</description> in ... on line 5

Warning: simplexml_load_file() [function.simplexml-load-file]: ^ in ... on line 5

Warning: Invalid argument supplied for foreach() in ... on line 8

this is a sample element of my xml

<?xml version="1.0" encoding="UTF-8"?>
<description>Νέας γενιάς & τεχνολογίας DAYLIGHT LED / SMD Tech</description>

You are not getting an error from the MySQL Server. Your error comes from simplexml_load_file() because the source XML file you are reading contains errors. In particular, a literal & must be encoded as &.

回答2:

try the function utf8_encode as follows

$col = '`'. implode('`,`',$columns) .'`';
$val = '"'. implode('","',utf8_encode($data)).'"';
$query = "INSERT INTO products ($col) VALUES ($val)";
mysql_query($query);

for your mySql table use:

) ENGINE=MyISAM DEFAULT COLLATION utf8_general_ci CHARSET=utf8;

hope it work for you.

UPDATE: I've missed that $data was an array...

the right code is:

$data[] = mysql_real_escape_string((string)utf8_encode($child));
