I know basic PHP and all I know I've learned on google during the past years. With that said, I'm developing a new website and I'm experimenting with clean URLs for SEO purposes and multi-regional languages compatibility.
So I have this array:
$list['requests']['en'] = array(
'index' => array(
0,
'subscribe',
'search'
),
'services' => array(
0,
'next' => array(
'service1',
'service2',
'service3'
),
'subscribe',
'search'
),
'service1' => array(
0,
'subscribe'
),
'service2' => array(
1,
'next' => array(
'view'
),
'jump' => 1,
'subscribe',
'search'
),
'service3' => array(
1,
'subscribe',
),
'view' => array(
2,
'subscribe'
),
'bad-request' => array(
0,
'subscribe'
)
);
Where $list['requests']['en'][$page][0] is the level of the page in the url and $list['requests']['en'][$page]['next'] is a list of valid pages that can follow.
That array is used to validate a URLs, so this is a valid one: www.website.com/services/service2/view
My real problem is that I want to loop throug that array and follow every page in the 'next' list so I have a function to create files like this: en/services.service1.view.php
I alreday created a chain of loops that do the job, but it's not generic. It's limited to the amount of loops I type in myself. This code for example, only runs throug 4 loops:
if(isset($list['requests'][$lang][$list_keys[$j]]['next'])){
for($l = 0; !empty($list['requests'][$lang][$list_keys[$j]]['next'][$l]) && $l < $for_max; $l++){
$next = $list['requests'][$lang][$list_keys[$j]]['next'][$l];
$file_next = $file[0].'.'.$next;
$file[] = $file_next;
if(isset($list['requests'][$lang][$next]['next'])){
for($n = 0; !empty($list['requests'][$lang][$next]['next'][$n]) && $n < $for_max; $n++){
$next_1 = $list['requests'][$lang][$next]['next'][$n];
$file_next_1 = $file_next.'.'.$next_1;
$file[] = $file_next_1;
if(isset($list['requests'][$lang][$next_1]['next'])){
for($o = 0; !empty($list['requests'][$lang][$next_1]['next'][$o]) && $o < $for_max; $o++){
$next_2 = $list['requests'][$lang][$next_1]['next'][$o];
$file_next_2 = $file_next_1.'.'.$next_2;
$file[] = $file_next_2;
if(isset($list['requests'][$lang][$next_2]['next'])){
for($p = 0; !empty($list['requests'][$lang][$next_2]['next'][$p]) && $p < $for_max; $p++){
$next_3 = $list['requests'][$lang][$next_2]['next'][$p];
$file_next_3 = $file_next_2.'.'.$next_3;
$file[] = $file_next_3;
}
}
}
}
}
}
}
}
This code saves every unique file name from the array chain. The output would be something like this:
index.php
services.php
services.service1.php
services.service2.php
services.service2.view.php
services.service3.php
...
I've tried to make generic functions to do this but with no success. Any ideas?
EDIT: I just came up with an idea to simplify the code with an include. Nevermind my variables, the point here is to make a script that perceives the depth of loops itself.
The hole script for the purpose of context:
<?php
include 'includes/lists/languages.php';
include 'includes/lists/requests.php';
$for_max = 15;
// create requests files for each language
for($i = 0; isset($list['languages'][$i]) && $i < $for_max; $i++){
$lang = $list['languages'][$i];
$requests_keys = array_keys($list['requests'][$lang]);
echo 'LANG: '.$lang.'<br/>';
for($j = 0; isset($list['requests'][$lang][$requests_keys[$j]]) && $j < $for_max; $j++){
if($list['requests'][$lang][$requests_keys[$j]][0] == 0){
$file = array();
$file[] = $requests_keys[$j];
/* NEXT PART LOOP */
$loop = array();
$depth = 0;
$part = array();
$part['next'] = array();
$part['file'] = array();
// these vars are unique for the first loop, then it's generic
$part['next'][$depth-1] = $requests_keys[$j];
$part['file'][$depth-1] = $file[0];
// loop through every 'next' part if it exists in the current part
if(isset($list['requests'][$lang][ $part['next'][$depth-1] ]['next'])){
include '___construct_files.recursive.php';
}
/* CREATE REQUEST FILE */
for($k = 0; $k < count($file); $k++){
$path = 'includes/requests/'.$lang.'/'.$file[$k].'.php';
// string to insert in the file
include '___construct_files.string.php';
// processing
if(!file_exists($path)){
file_put_contents($path, $string);
echo '<br/># created - '.$path.'<br/>';
}else if(file_exists($path)){
echo '<br/># exists - '.$path.'<br/>';
}else{
echo '<br/># error - '.$path.'<br/>';
}
}
}
}
echo '<br/><br/>';
}
?>
The loop is included and verifies if it's needed to be included again in itself (___construct_files.recursive.php):
<?php
for($loop[$depth] = 0; !empty($list['requests'][$lang][ $part['next'][$depth-1] ]['next'][ $loop[$depth] ]) && $loop[$depth] < $for_max; $loop[$depth]++){
$part['next'][$depth] = $list['requests'][$lang][ $part['next'][$depth-1] ]['next'][ $loop[$depth] ];
$part['file'][$depth] = $part['file'][$depth-1].'.'.$part['next'][$depth];
$file[] = $part['file'][$depth];
// if next part is set, increase depth and include loop
if(isset($list['requests'][$lang][ $part['next'][$depth] ]['next'])){
$depth++;
include '___construct_files.recursive.php';
}
}
// decrease depth when higher depth loop ends so the current loop can resume
$depth--;
?>
