Group by the array value - php

Question

I'm using this code:
$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
foreach($permissions as $permission) {
for ($i = 1; $i <= 5; $i++) {
$mode = $_POST['permission'][$i][$permission];
if($mode == 1)
echo "{$permission} = {$i}:::";
}
}
And the output if I check some checkboxes is:
canview = 1:::canview = 5:::canpostreplies = 3:::canpostpolls = 5:::
I wan't the output to be following:
instead of canview = 1:::canview = 5:
canview = 1,5
and if I'll have for example:
canpostpolls = 1:::canpostpolls = 2:::canpostpolls = 3
It'll be:
canpostpolls = 1,2,3:::canview = 1,5
I hope you understand it guys. This is my own idea for this, you are free to share your ideas with me, this data will be exported to the mysql table.

$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
$setpermissions = array();
foreach($permissions as $permission) {
for ($i = 1; $i <= 5; $i++) {
$mode = $_POST['permission'][$i][$permission];
if($mode == 1) {
if (!isset($setpermissions[$permission])) {
$setpermissions[$permission] = array();
}
$setpermissions[$permission][] = $i;
}
}
}
$plist = array();
foreach ($setpermissions as $name => $sp) {
$plist[] = "$name = " . implode(',', $sp);
}
echo implode(':::', $plist);

You need to filter your data a bit more... maybe something like this:
$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
$filtered_perms = array();
foreach($permissions as $permission) {
for ($i = 1; $i <= 5; $i++) {
$mode = $_POST['permission'][$i][$permission];
if($mode == 1) {
if(!is_array($filtered_perms[$permission])) {
$filtered_perms[$permission] = array();
}
$filtered_perms[$permission][] = $i;
}
}
Then, you can do something like:
$final_perms = array();
foreach($filtered_perms as $key => $val) {
$final_perms[$key] = implode(",", $val);
}
Hope that helps!

$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
$userPermissions = array();
foreach($permissions as $permission) {
for ($i = 1; $i <= 5; $i++) {
$mode = $_POST['permission'][$i][$permission];
if($mode == 1)
$userPermissions[$permission][] = $i;
}
}
foreach($userPermissions as $permission => $values) {
echo "{$permission} = " . implode(',', $values) . ":::";
}

You can do something like this - essentially, combining the values before outputting them.
$permissions = array("canview", "canpostthreads", "canpostreplies", "canpostpolls", "all");
foreach($permissions as $permission) {
$vals = array();
for ($i = 1; $i <= 5; $i++) {
$mode = $_POST['permission'][$i][$permission];
if($mode == 1)
$vals[] = $i;
}
if(count($vals))
echo $permission . ' == ' . implode(',', $vals);
}
