I have 2 kind of classes: math and physics.
In the loop , count(lessonclasses) is equal to 2 then 3.
How can I proceed for my expected output ,
My code is :
$result[]=array();
foreach($lessons as $nameLesson)
{
$lessonclasses=$Board->GetLessonsClass($iduser,$nameLesson);
$tabPrice=$redevance->detailPriceForLesson($nameLesson)
$price=$tabPrice[0];
$frequency=$tabPrice[1];
//echo "nb of class per lesson: ".count($lessonclasses);
for($i=0;$i<count($lessonclasses);$i++)
{
//var_dump($lessonclasses);
$name=$lessonclasses[$i][0];
$amount=$lessonclasses[$i][1];
$timelessonstart=$lessonclasses[$i][2];
$timelessonend=$lessonclasses[$i][3];
$result[$i][]=array($name,$price."€/".$frequency,$timelessonstart,$timelessonend,$amount);
//$arrayOptions[$nbLessons][]=$options; //for keep values
//$nbLessons=$nbLessons+1;
}
}
var_dump($result);
I have an array like :
array(3) {
[0]=> array(2) {
[0]=> array(5) {
[0]=> string(15) "maths"
[1]=> string(11) "10.00"
[2]=> string(10) "2015-06-17"
[3]=> string(1) "-"
[4]=> string(6) "10.00"
}
[1]=> array(5) {
[0]=> string(31) "physique"
[1]=> string(10) "6.00"
[2]=> string(10) "2015-01-01"
[3]=> string(1) "-"
[4]=> string(5) "36.00"
}
}
[1]=> array(2) {
[0]=> array(5) {
[0]=> string(15) "maths"
[1]=> string(11) "20.00"
[2]=> string(10) "2015-06-17"
[3]=> string(1) "-"
[4]=> string(6) "100.0"
}
[1]=> array(5) {
[0]=> string(31) "physique"
[1]=> string(10) "16.00"
[2]=> string(10) "2015-05-01"
[3]=> string(1) "-"
[4]=> string(5) "36.00"
}
}
[2]=> array(1) {
[0]=> array(5) {
[0]=> string(15) "Maths" [1]=> string(11) "11.00" [2]=> string(10) "2015-05-17" [3]=> string(1) "-" [4]=> string(5) "20.00" } } }
My expected output is :
array(3) {
[0]=> array(2) {
[0]=> array(5) {
[0]=> string(15) "maths"
[1]=> string(11) "10.00"
[2]=> string(10) "2015-06-17"
[3]=> string(1) "-"
[4]=> string(6) "10.00"
}
[1]=> array(2) {
[0]=> array(5) {
[0]=> string(15) "maths"
[1]=> string(11) "20.00"
[2]=> string(10) "2015-06-17"
[3]=> string(1) "-"
[4]=> string(6) "100.0"
}
[2]=> array(5) {
[0]=> string(31) "math"
[1]=> string(10) "11.00"
[2]=> string(10) "2015-05-01"
[3]=> string(1) "-"
[4]=> string(5) "36.00"
}
}
[1]=> array(2) {
[0]=> array(5) {
[0]=> string(31) "physique"
[1]=> string(10) "6.00"
[2]=> string(10) "2015-01-01"
[3]=> string(1) "-"
[4]=> string(5) "36.00"
}
[1]=> array(5) {
[0]=> string(31) "physique"
[1]=> string(10) "16.00"
[2]=> string(10) "2015-05-01"
[3]=> string(1) "-"
[4]=> string(5) "36.00"
}
}
} }
