explode() to numbers instead of strings

[PeterPopper]

I need help using the explode function and having the results as numbers, not strings:

 

//this is the first line of the textFiles being read from:

60,66,61,87,87,76,68,70,69,66,69,73,70

 

while(! feof($fileOpening))

  {

$externalDataRetrieved[] = rtrim(fgets($fileOpening));

  }

 

$theChartData = explode (",", $externalDataRetrieved[0]);

 

The results in $theChartData are all strimngs and not numbers

[Daniel0]

$theChartData = array_map('intval', $theChartData);

 

When you split a string it'll still be a string. PHP can't possibly know that you want the string "60" to be an integer, so if you want it to know it you'll have to tell it.

You want these functions:

http://us3.php.net/manual/en/function.intval.php

http://us3.php.net/manual/en/function.array-map.php

 

here you go:

$theChartData = array_map('intval',$theChartData);

#My fix may be quicker, but i'm not sure about efficency,

 

*1

 

thats it

 

that way php treats it as a float if it has a decimal, an integer if its whole.

Thanks very much for the prompt and very helpful replies. This is what I did while waiting for a response:

 

foreach ($theChartData as $key => $value)

{

$theChartDataNew[$key]= (int)str_replace('"','',$value);

}

 

 

knsito and Daniel0, that is the solution, it worked perfectly. Thanks.

 

HavokDelta6, that is a cool tip that I have never seen. Thanks, mate.
