PHP looping through array

[format]

Hi All,  I am using the below with great success.  It finds for me the MIn and max values allong with the company names. The problem that has just presented itself is some of the data returned in the SLevel is text.  I need to ignore text and only include numeric values.  Is this possible.  I have tried to work this out but have hit a brick wall.

 

Many thanks
 

Jon

 

 

 

$SLevels = array();

foreach ($xml->Type->Company as $item)
{
    $companyName = (string) $item->Name; // get the company name
    $tmp = (array) $item->$Level;
    if($tmp[0] != '-')
        $SLevels[] = array($tmp[0], $companyName); // add SLevel and company name to array
}

$minSLevel = min($SLevels); // get minimum value
$minSLevel[0] = str_replace(',', '', $minSLevel[0]);

$premium = $minSLevel[0];
$company = $minSLevel[1];

 

$maxSLevel = max($SLevels); // get minimum value
$maxSLevel[0] = str_replace(',', '', $maxSLevel[0]);

$maxpremium = $maxSLevel[0];
$maxcompany = $maxSLevel[1];

Seems weird that you have this mixture of numbers and strings, but whatever.

 

So you only want to add to $SLevels if the data is a number? I figure

if($tmp[0] != '-')

would be a good place to do that. To test for a number, try is_numeric.

Thanks for reply, ya Im not in control of the data.  Its coming from a live quote system and they replace what should be a numberwith a  text message for any companies that  dont return a quote.

 

I tired the below but I think the problem here is I just dont understand how it should work..  I can use is_numeric and even concidered strpos but no joy.  Im trying to only add to the array numbers.

 

 

if(is_numeric($tmp[0]))
        $maxLevels[] = $tmp[0];

[format]

if(is_numeric($tmp2[0]))// ignore non number
        $maxLevels[] = $tmp2[0]; // add JLevel to array

 

Thanks requinix.
 

I have it working.  I had a typo which.
