Foreach array with different values - php

Question

Need little help, i get always stupid errors, when i try to do this, i want to foreach array, and inside that do a for loop, is this possible?
Here is my code
$image = new SimpleImage();
$slike=array($_FILES['slika1']['tmp_name'],$_FILES['slika2']['tmp_name'],$_FILES['slika3']['tmp_name'],$_FILES['slika4']['tmp_name']);
$koliko = count($slike);
foreach ($slike as $slika) {
for ($i = 1; $i <= $koliko; $i++)
{
$slicica="../images/usluge/".mysql_insert_id()."-".$i.".jpg";
$image->load($slika);
$image->resizeToWidth(800);
$image->save($slicica);
}
}
I want to get new pictures with this name, example.If last id was 2 i want to get this filenames etc
2-1.jpg
2-2.jpg
2-3.jpg
2-4.jpg
Still with my code i dont get correct values :(
Or maybe there is easy way to do that :)

Answer 1

I think what you need is to replace your following line:
$image->load($slika);
for this one:
$image->load($slike[$i-1]);

Answer 2

you probably have a problem in you foreach as if we do a var_dump on an array we will see the following :
array(3) { [0]=> string(5) "test1" [1]=> string(4) "tes2" [2]=> string(5) "test3" }
so you need to change it to :
foreach ($slike as $key => $slika) {
you can also use move_uploaded_file to achieve what you are trying to do and use linux command convert :
foreach ($slike as $key => $slika) {
for ($i = 1; $i <= $koliko; $i++)
{
$slicica="../images/usluge/".mysql_insert_id()."-".$i.".jpg";
if(move_uploaded_file(slika,slicica)){
exec("convert $slicica -resize 200 $slicica");
}else{die('problem loading the file');}
}
}

Answer 3

$i=1;
// insert into mysql table..
// [...]
$mysqlId = mysql_insert_id();
foreach ( $_FILES as $key => $value) {
$slicica="../images/usluge/".$mysqlId."-".$i.".jpg";
if(move_uploaded_file($_FILES[$key]["tmp_name"],slicica)){
$image->load($slicica);
$image->resizeToWidth(800);
$image->save($slicica);
}
else {
// error handling
}
$i++;
}
