PHP array ordering - php

I was wondering how I could sort this array, when I use asort right now it does
14
17
16
15.
How would I go to have
14

You want ksort(), which will sort the array by key instead of value.


You're looking for the sort by key function:
ksort()


I would check out http://us.php.net/manual/en/function.sort.php. There are some examples there of how how to implement the sort the way you want. Also if its sorted but you want the reverse order use array_reverse().

I specifically want's to target the "fag" array.
I tried the following, but it returns an error:
<?php
include("lectio/lectio.php");
$lectio = new lectio();
$skemamag = $lectio->get_skema_til_elev(94, 16305782848);
var_dump($skemamag);
?>
<div class="skema-lektioner-wrapper">
<?php foreach ($skemamag['dagskema']['Mandag (14/8)']['fag'][8] as $key => $val) {
echo '<p class="lektioner lektioner-'.$val.'">';
echo $val;
echo '</p>';
}?>
</div>
Error looks like this:
Warning: Invalid argument supplied for foreach() in /var/www/square-brain.com/itk/index.php on line 62
I use the api LectioAPI on github, link here
I specifically use this file
What am i doing wrong?

You need to look closer at you array structure. PHP is big on arrays, so you need to become familiar with them
<?php
foreach ($skemamag['dagskema']['Mandag (14/8)']['fag'] as $fag) {
// $fag is also an array, not sure if you want both of its members
// or just one
echo '<p>'
echo $fag['tekst'];
echo ' ';
echo $fag['note'];
echo '</p>';
}
?>
To avoid using the 'Mandag (14/8)' array by name, as it will probably change over time, you could do
<?php
foreach ($skemamag['dagskema'] as $d => $dag) {
echo echo "<p>$d</p>"; // echo that dag
foreach ( $dag['fag'] as $fag) {
echo '<p>'
echo $fag['tekst'];
echo ' ';
echo $fag['note'];
echo '</p>';
}
}
?>

';
$regex = "/R\$[0-9]{1,},[0-9]{1,}/";
$result = preg_match_all($regex, $content, $rs);
var_dump($rs);
What's going on?

Try this code:
$content = "R$13,57 more text R$123,456";
$regex = "/$.*(R\$[0-9]{1,},[0-9]{1,}).*^/";
$result = preg_match_all($regex, $content, $rs);
var_dump($rs);
You need to place the group you are trying to match inside parentheses.

At least one output file must be specified

I am using this command in ffmpeg
ffmpeg -i test.flv -i /var/www/phpvibe/logo.gif -filter_complex "scale=1200:-1,overlay=0:0" -s 1280x720 -vcodec libx264 -s 640x360 -movflags test.mp4 2>&1
But i am getting this

php code:-
$output ='{ffmpeg-cmd} -i {input} -i /var/www/phpvibe/logo.gif -filter_complex "scale=1200:-1,overlay=0:0" -s 1280x720 -vcodec libx264 -s {ffmpeg-vsize} -threads 4 -movflags {output}.mp4 2>&1';

You put a -movflags without specifying a value before your output file. It thinks test.mp4 is the flag value hence your problem.

preg_match_all Specific REGEX

Could some one help me to formulate this REGEX because i am not familiar with preg_match_all filters, I want REGEX for :
sentence containing "petition" and delimited by . or a line break
Postal code have the format XXXXX (number) (with eventual space between the numbers ex : X XX XX or X XXXX )
$phone_regex = '~(?:\+?169|0)(?:\s*\d{3}){2}\s*\d{4}~';
$phone_res = preg_match_all($phone_regex, $content, $phone_matches);
REGEX 1
input :
1=> Plus de 5500 personnes ont déjà signé la pétition en ligne. Dans la droite ligne de ce mouvement, une manifestation est organisée jeudi devant la mairie de Metz.
2=> Dans un communiqué pétition
La décision de la Ville de Metz de confier les cinémas
output:
1=> Plus de 5500 personnes ont déjà signé la pétition en ligne.
2=> Dans un communiqué pétition
REGEX 2
input :
1=> 50040
2=> 50 040
3=> AA123
output :
1=> 50040
2=> 50 040

([^\.]*pétition[^\.^\n]*\.?)
And for your zip code : (\d\s?\d\s?\d\s?\d\s?\d)

Creating an object from an array of multiple values

I have this function:
function getPostInfo($query, $fields, $type, $limit, $since, $until, $lang, $stopwords, $identifier) {
$url = file_get_contents('https://graph.facebook.com/search?q='.spaces($query).'&fields='.$fields.'&limit='.$limit.'&until='.$until);
$j = json_decode($url);
foreach($j->data as $v) {
if ($v->type == $type) {
$author_id = $v->from->id;
$original_id = $v->id;
$post_url = getPostUrl($original_id, $author_id);
//$description = stopWords($v->message);
$description = $v->message;
$pub_date = $v->created_time;
$post[]= array(
'author_id' => $author_id,
'orginal_id' => $original_id,
'post_url' => $post_url,
'descritpion' => $description,
'pub_date' => $pub_date
);
}
}
return (object)$post;
}
If I call for example:
$post = getPostInfo($query, $fields, $type, $limit, $since, $until, $lang, $stopwords, $identifier);
echo $post->pub_date;`
it returns empty..
I tried to strip the [] from the $post array in the function...and in this case it returns only ONE value..
Instead it should return more values, because the object should get more values from the foreach loop in the above function..
But it's not happening..
I tried also to work with normal arrays, without an object, like this:
$post = getPostInfo($query, $fields, $type, $limit, $since, $until, $lang, $stopwords, $identifier);
echo $post['pub_date'];
In this case it always returns NULL..
What I am doing wrong?
How to assign more values to the array and getting them back when I need, knowing that the things I get should contain more values. It's like an array of an array...
I am a little confused..
I like the solution with objects, but if there is any other way, then better.
This is an example of what I get from the array $post:

You need to call it out like this
echo $post[0]["author_id"];
echo $post[1]["author_id"];
You can also use a for each loop if you need to display all the values at once
foreach($post as $p){
echo $p["author_id"];
}

I'd stick to arrays personally, so return with return $post;
You would have to echo $post[0]['pub_date']; or $post[1]['pub_date']; or $post[2]['pub_date']; for the different rows.
Or you can loop
foreach ($post as $post_values){
echo $post_values['pub_date'];
}

Try doing somehting like this
$post[] = (object) array(
'author_id' => $author_id,
'orginal_id' => $original_id,
'post_url' => $post_url,
'description' => $description,
'pub_date' => $pub_date
);
