In a lyrics application I'm coding, I'm using an array to print an artists table. The artists array looks like this:
$artists = [
[ "Avril Lavigne" ],
[ "3 Doors Down" ],
[ "Celine Dion" ],
[ "Evanescence" ],
[ "Shania Twain" ],
[ "Green Day" ],
//...
];
Before printing it, I do some modification to the array. I have a folder for each artist that contains the lyrics files. I add the folder names to the $artists array for later use:
$folder_fix = [
[" ", "_" ],
[".", "" ],
["&", "n" ],
];
for ($i = 0; $i < count($artists); $i++) {
$folder_name = strtolower($artists[$i][0]);
for ($k = 0; $k < count($folder_fix); $k++) {
$folder_name = str_replace($folder_fix[$k][0], $folder_fix[$k][1], $folder_name);
}
array_push($artists[$i], $folder_name);
}
Later, I add the album and track count for each artist to the array:
$lyrics_base = "lyrics/";
for ($i = 0; $i < count($artists); $i++) {
$albums_path = $lyrics_base . $artists[$i][1] . "/*";
$tracks_path = $lyrics_base . $artists[$i][1] . "/*/*";
$albums = count(glob($albums_path));
$tracks = count(glob($tracks_path));
array_push($artists[$i], $albums);
array_push($artists[$i], $tracks);
}
The end result of the array looks like this:
$artists = [
[ "Avril Lavigne", "avril_lavigne", 5, 61 ],
[ "3 Doors Down", "3_doors_down", 5, 13 ],
[ "Celine Dion", "celine_dion", 7, 22 ],
[ "Evanescence", "evanescence", 4, 10 ],
[ "Shania Twain", "shania_twain", 3, 12 ],
[ "Green Day", "green_day", 8, 26 ],
//...
];
Now, my problem is that this process happens every time I visit the page. The 2nd, 3rd, and the 4th columns are created again and again. I think this is redundant.
I want to save the end result of the array and use it on the page. If this was JavaScript I'd use JSON.stringify(), but in PHP I don't know how to get the end result of the array. print_r() doesn't do the job, because it prints it like this:
Array
(
[0] => Array
(
[0] => Avril Lavigne
[1] => avril_lavigne
[2] => 5
[3] => 61
)
[1] => Array
(
[0] => 3 Doors Down
[1] => 3_doors_down
[2] => 5
[3] => 13
)
...
I want it like this:
[
[
"Avril Lavigne",
"avril_lavigne",
5,
61
],
[
"3 Doors Down",
"3_doors_down",
5,
13
],
//...
]
Is there a way to print the array the JSON.stringify() way?
