Converted 0->feild0, 1->field1,2->field2....
This is just one example in which i get comma separated value in string and convert it into multidimensional array and then using foreach loop i changed key value of array
<?php
$str = "abc,def,ghi,jkl,mno,pqr,stu
abc,def,ghi,jkl,mno,pqr,stu
abc,def,ghi,jkl,mno,pqr,stu
abc,def,ghi,jkl,mno,pqr,stu;
echo '<pre>';
$arr1 = explode("\n", $str); // this will create multidimensional array from upper string
//print_r($arr1);
foreach ($arr1 as $key => $value) {
$arr2[] = explode(",", $value);
foreach ($arr2 as $key1 => $value1) {
$i =0;
foreach ($value1 as $key2 => $value2) {
$key3 = 'field'.$i;
$i++;
$value1[$key3] = $value2;
unset($value1[$key2]);
}
}
$arr3[] = $value1;
}
print_r($arr3);
?>
