NOTE: First line in the code is line 107, and in line is "foreach($items as $item)" 115 line.

 

How to solve this ?

Thanks.

that probably means that $items is not an array.

[dreamwest]

You can also make $items an array before the script if $rss_link  has no value

 

$items = array();

[ebchost]

that probably means that $items is not an array.

 

how to skip this item? becose is imposible that all data is not array?

[WebStyles]

you can check it with something like this:

if(is_array($items)){
echo '<br>$items is an array<br>';
}else{
echo '<br>Oppss. $items is NOT an array<br>';
}

An the end of the post is code of the function for reading RSS (source_add_all)

 

with out this, i write som record, with this, i write 0 record in database

 

 

this problem show up after when i add "LIBXML_ERR_NONE"

in line

$rss_link = simplexml_load_file($rss_izvor,  LIBXML_ERR_NONE)

 

before that, i have brake of function with out error 1 time of 15-20 times

 

function source_add_all($table, $id)
{
	$table = mysql_real_escape_string($table); 
	$id    = (int)$id;		

	$query = mysql_query("SELECT * FROM `rss_sajtovi`") or die(mysql_error());

	while($row= mysql_fetch_assoc($query))
		{
			$rss_izvor_id 		= $row['ID_SAJTA'];
			$rss_izvor_naziv 	= $row['NAZIV'];
			$rss_izvor_logo 	= $row['LOGO'];
			$url_sajta 		= $row['URL'];
			$rss_izvor 		= $row['RSS'];
			$rss_kategorija 	= $row['kategorija'];
			$rss_kategorija_id 	= $row['kategorija_id'];
			$rss_odobren 		= $row['odobren'];
			$korisnik_id 		= $row['korisnik_id'];
			$kontrola 		= $row['kontrola'];		



			$rss_link 		= simplexml_load_file($rss_izvor,  LIBXML_ERR_NONE);
			//var_dump($rss_izvor);

			if($rss_izvor)
			{		

				$items = $rss_link->channel->item;
