I need to remove all elements that contains dot in array that i receive fron ftp_nlist(), this is how i do that:
$connection = ftp_connect($host);
if(!$connection){
echo "Can't connect to $host ($login:$password)\n";
#print_r(error_get_last());
ftp_close($connection);
exit();
}
ftp_login($connection, $login, $password);
ftp_pasv($connection, TRUE);
$files_list = ftp_nlist($connection, $path);
print_r($files_list);
for($i = 0; $i< count($files_list); $i++){
if( strstr($files_list[$i], '.') ){
unset($files_list[$i]);
}
}
print_r($files_list);
echo 'Ok';
However it works strange

Ok
As you can see not all elements with dots was removed. I can't see clear reason why.
Every time you unset() an array element the count() in the condition is decreased by 1. So instead of using count($files_list); in the condition (this is evaluated each iteration), set it first so it doesn't change:
$count = count($files_list);
for($i = 0; $i < $count; $i++){
if(strpos($files_list[$i], '.') !== false){
unset($files_list[$i]);
}
}
I would prefer foreach():
foreach($files_list as $key => $file){
if(strpos($file, '.') !== false){
unset($files_list[$key]);
}
}
Also notice that strpos() is better suited here.

I want all arrays data in one array not all arrays in one array only the data of all arrays in one array without any other array in php. I have tried to do too many things but still don't work for me.
I also tried
json_encode
with
preg_match
But still don't work for me.
Here is my code
function fetchHashtags($getData){
$body = $getData;
$hashtag_set = [];
$array = explode('#', $body);
foreach ($array as $key => $row) {
$hashtag = [];
if (!empty($row)) {
$hashtag = explode(' ', $row);
$hashtag_set[] = '#' . $hashtag[0];
}
}
print_r($hashtag_set);
}
Output
Array

And one more thing i also want to remove some data that don't look like hashtags.
for example:
Array
(
[0] => #Residência
[1] => architecture // This should be removed
[2] => #casanaserra
[3] => mountainhouse // This also should be removed
[4] => #interiores
)
As you can see from my code you can use array_merge for merge arrays then use array_filter for filter value without # or other rules you need:
$array = [['1', '#2', '3', '#4'], ['5', '#6']];
$flatArray = array_merge(...$array);
$filteredArray = array_filter($flatArray, function($a) {
if (str_contains($a, '#')) {
return $a;
}
});
print_r($filteredArray);
Result:
Array (
[1] => #2
[3] => #4
[5] => #6 )
Reference:
array_merge
array_filter
str_contains
After seeing your code and the context of the situation I changed things:
Instead of use explode i used preg_split for split \n and space;
Delete array_map because you don't need it.
$array = ["
My name is Faraz shaikh i am a php developer and this my #instagram profile.Check out my #merge and my #packages with new #hashtags
#chinese #art #colors #home #harmory #peace #handmade #paintings #etsy
", "
My name is Hunain shaikh i am a php developer and this my #Facebook profile.Check out my #Berge and my #Hackages with new #tags
#english #Kite #colours #me #memory #pee #made #paints #etsafsy
"];
function fetchHashtags($getData) { // This Functions takes out the hashtags from the string and put it in to arrays.
$body = $getData;
$hashtag_set = [];
$array = preg_split('/[\s]+/', $body);
$mapArray = array_map(function($a) {
return str_replace(' ', '', $a);
}, $array);
$filteredArray = array_filter($mapArray, function($a) {
if (str_contains($a, '#')) {
return $a;
}
});
return $filteredArray;
}
$recentNumberOfPosts = 1;
$zeroPost = 0; //Get Post from 0 to recentNumberOfPosts | NOTE: default = 4
$finalArr = [];
while ($zeroPost <= $recentNumberOfPosts) {
// fetchHashtags($hashtagRecent['data'][$zeroPost]['caption']);
$finalArr[] = fetchHashtags($array[$zeroPost]);
$zeroPost++;
}
print_r(array_merge(...$finalArr));
Fiddle
I'm able to scan directory of files uploaded to server via FTP
Now I want to discard the empty arrays and add path and total count of images into MySQL database. I will use that path and count of images to use them in HTML player and run these pictures as video.
Here is my code:
<?php
$path = '/home/zackpc/usr/share/zoneminder/www/events/1';
// an unsorted array of dirs & files
$files_dirs = iterator_to_array( new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path),RecursiveIteratorIterator::SELF_FIRST) );
echo '<html><body><pre>';
// create a new associative multi-dimensional array with dirs as keys and their files
$dirs_files = array();
foreach($files_dirs as $dir){
if(is_dir($dir) AND preg_match('/\/\.$/',$dir)){
$d = preg_replace('/\/\.$/','',$dir);
$dirs_files[$d] = array();
foreach($files_dirs as $file){
if(is_file($file) AND $d == dirname($file)){
$f = basename($file);
$dirs_files[$d][] = $f;
}
}
}
}
print_r($dirs_files);
echo '</pre></body></html>';
?>
I am getting following output:

Only loop once. Only store what you need: paths and image counts.
foreach($files_dirs as $file){
if (is_file($file)) {
$d = dirname($file);
if (!isset($dirs_files[$d])) {
$dirs_files[$d] = 0;
} else {
++$dirs_files[$d];
}
}
}
I've got to say:
I got lost in your code.
I did not test my answer, so no guarantees that it is perfect.
What is the fastest way to reach a URL with PHP without any output needed?
I did a testing on the code below by using file_get_contents and CURL, but the result inconstant and very close to each other.
function abtest()
{
$arr_to_return = array();
$t = microtime(true);
file_get_contents('http://127.0.0.1/test.html');
$e = microtime(true);
$arr_to_return['file_get_contents'] = $e-$t;
$t = microtime(true);
$handle = curl_init('http://127.0.0.1/test.html');
curl_setopt($handle, CURLOPT_NOBODY, TRUE);
curl_exec($handle);
curl_close($handle);
$e = microtime(true);
$arr_to_return['curl'] = $e-$t;
return $arr_to_return;
}
$limit = 20;
$count = 0;
$result = array();
$filegetcontents = 0;
$curl = 0;
do{
$test = abtest();
$result['file_get_contents'][] = $test['file_get_contents'];
$filegetcontents += $test['file_get_contents'];
$result['curl'][] = $test['curl'];
$curl += $test['curl'];
$count++;
} while ( $count < $limit);
echo '<pre>';
print_r($result);
echo '</pre>';
echo 'Average: file_get_contents ('.($filegetcontents/$limit).') curl ('.($curl/$limit).')';
As per suggested, I put it into a function and loop 20 times on localhost with direct IP.
Result as below:

Seems result of CURL is better than file_get_contents most of the time. Any faster way to do this other than above?

I am using the code below;
{
private function listFiles($bucket = null , $prefix = null) {
$ls = S3::getBucket($bucket, $prefix);
if(!empty($ls)) {
foreach($ls as $l) {

if(!empty($rv)) {

What changes can I make to my code to get the above results. I am using Donovan Schönknecht Amazon S3 library for codeigniter.
You could use a foreach
$newarr=array();
foreach($entries as $v)
{
if(strpos($v,'/')!==false)
{
$v=explode('/',$v);
if(isset($v[1]) && strlen($v[1])>0){}else{$newarr[]=$v[0];}
}
else { $newarr[]=$v;}
}
print_r($newarr);
Working Demo
You can overwrite the elements with $array[3] = ""; e.g. Then u have empty array-elements and then you could use a function like this:
function empty_array($array){
foreach($array as $ar => $value) {
if($value == '') {
unset($array[$ar]);
}
}
return $array;
}
$new_array = emtpy_array($old_array);

i wanted to read the csv file i load from yahoo that includes some stock data. 2 days before i used this code:
$ticker_url="";
for($i=0;$i<200;$i++){
if($i==199){
// $ticker=array with all 200 stock ticker....
$ticker_url=$ticker_url.$ticker[$i];
}else{
$ticker_url=$ticker_url.$ticker[$i]."+";
}
}
$url="http://finance.yahoo.com/d/quotes.csv?s='$ticker_url'&f=snxab2l1va2p2opm3m4ghd1t1=.csv";
$filehandle=fopen($url,"r");
while(!feof($filehandle)){
$line=fgetcsv($filehandle,1024);
echo $line[0]."<br/>";
}
fclose($filehandle);
But now it doesn't work anymore. There is no problem with $url works fine. but reading the lines with fgetcsv hust loops 6 times and got no elemnts in it...
pls help.
$ticker = array('GOOG', 'ACE', 'FDX'); // test tickers
$ticker_url = '';
$count = count($ticker);
for ($i = 0; $i < $count; $i++)
{
$ticker_url .= (0 === $i)
? $ticker[$i]
: '+' . $ticker[$i];
}
$url = 'http://finance.yahoo.com/d/quotes.csv?s=' . $ticker_url . '&f=snxab2l1va2p2opm3m4ghd1t1=.csv';
ini_set('auto_detect_line_endings', TRUE);
if (($handle = fopen($url, 'r')) !== FALSE)
{
while (($data = fgetcsv($handle, 1024, ',', '"')) !== FALSE)
{
print_r($data);

fclose($handle);

Alternative method since above does not seem to work on your server:
$ticker_url = '';
$count = count($ticker);
for ($i = 0; $i < $count; $i++)
{
$ticker_url .= (0 === $i)
? $ticker[$i]
: '+' . $ticker[$i];
}
$url = 'http://finance.yahoo.com/d/quotes.csv?s=' . $ticker_url . '&f=snxab2l1va2p2opm3m4ghd1t1=.csv';
$csv = explode("\n", file_get_contents($url));
unset($csv[count($csv) - 1]); // remove empty row
foreach ($csv as $line)
{
$data = str_getcsv($line);
print_r($data);
}
Add an echo $url; , look at the output and then ... look over the other parameters of fgetcsv : http://php.net/manual/en/function.fgetcsv.php (delimiter and enclosure).
