when i turn this text file into array $handle, how can i test the second field (250,150,300,200)
i want to check if its below 100, if it is then display the row!!
if $secondfield < 100
then echo
how could i manipulate the array to do this in php thanks ?
I presume you have each line in the file as an element in your array. In that case:
$data = array_map(function($e){ return explode(',', $e); }, $array);
$desiredData = array_filter(function($e){ return $e[1] < 100; }, $data);
Explode every string, so you have four arrays:
foreach($strings as $string){
$arr = expode(',', $string);
if( intval($arr[1]) < 100 ){
echo $string;
}
}
Assuming you have a csv (I copied and modified some code from the php manual):
if (($handle = fopen("test.csv", "r")) !== FALSE) {
while (($line = fgets($handle)) !== FALSE) {
$data = str_getcsv($line);
if ($data[1] < 100)
echo $line;
}
fclose($handle);
}
