I'm using laravel 5.8 and am trying to get a foreach to implode
foreach($stocks->currency as $currency)
{
$d1 = $currency->cost;
$d2 = $currency->currency->name;
$currencies = array(' ' . $d1 . ' ' . $d2);
echo implode("or", $currencies);
}
Is my code block
However, this returns the following :
clearly this lacks the "or" that the implode should add
Thank you in advance!
try something like
$currencies = [] // Create an empty array
foreach($stocks->currency as $currency)
{
$d1 = $currency->cost;
$d2 = $currency->currency->name;
$currencies[] = ' ' . $d1 . ' ' . $d2; // Add a new value to your array
}
echo implode("or", $currencies); // implode the full array and separate the values with "or"

I'm trying to take a variable from an xml file and save it as a php file
$xmlresponse = simplexml_load_string($dom->saveXML());
$shipmentid = $xmlresponse->ListInboundShipmentsResult->ShipmentData->member->ShipmentId;
echo '<br />' . $shipmentid . '<br />';
$todaydt = new DateTime('today');
$today3 = $todaydt->format('m-d-Y') . PHP_EOL;
$today = rtrim($today3);
$var_str = var_export($shipmentid, true);
$var = "<?php\n\n\$shipmentid = $var_str;\n\n?>";
file_put_contents('shipmentid_' . $today . '.php', $var);
}
But in my shipmentid_11-11-2016.php file it is giving me
$shipmentid = SimpleXMLElement::__set_state(array(
0 => 'shipmentid',
));
How can I save the variable so it is just simply
$shipmentid = 'shipmentid';
?
When you do
echo '<br />' . $shipmentid . '<br />';
php implicitly converts $shipmentid value to a string. var_export does not do it, so you need to convert it by yourself:
$var_str = strval($shipmentid);
Next thing is that $var_str is a string and does not contains any quotes around. So, again you need to write quotes by yourself:
// with double quotes
$var = "<?php\n\n\$shipmentid = \"$var_str\";\n\n?>";
// with single quotes
$var = "<?php\n\n\$shipmentid = '$var_str';\n\n?>";
I am writing the following code from a CSV to get stock data, When I have downloaded the string it is splitting it in the following way
<COMPANY NAME>,<STOCK PRICE>,<STOCK CHANGE>
<COMPANY2 NAME>,<STOCK PRICE2>,<STOCK CHANGE2>
I have tried to split the array by using the /n character using the PHP function explode. However this did not split it properly. Here is my code:
public function getQuotes()
{
$result = array();
$format = $this->format;
$stockString = "";
foreach ($this->stocks as $stock)
{
$stockString = $stockString . $stock . "+";
}
//Remove the last "+"
$stockString = substr($stockString,0,strlen($stockString)-1);
$s = file_get_contents("http://finance.yahoo.com/d/quotes.csv?s=". $stockString . "&f=" . $format . "&e=.csv");
//The splitting is to be done here.
}
}
Thank you in advance
Use file function instead of file_get_contents - it will split the content for you, as php manual says:
Returns the file in an array. Each element of the array corresponds to
a line in the file, with the newline still attached. Upon failure,
file() returns FALSE.
Then you can use str_getcsv for each element of array to get field values.
public function getQuotes()
{
$result = array();
$format = $this->format;
$stockString = "";
foreach ($this->stocks as $stock)
{
$stockString = $stockString . $stock . "+";
}
//Remove the last "+"
$stockString = substr($stockString,0,strlen($stockString)-1);
$s = file("http://finance.yahoo.com/d/quotes.csv?s=". $stockString . "&f=" . $format . "&e=.csv");
foreach($s as $line) {
$values = str_getcsv($line);
}
}
I have this string:
[25-03-15, 1236], [26-03-15, 3000], [27-03-15, 3054], [30-03-15, 4000]
I want to get two parts from it as below:
['25-03-15','26-03-15','27-03-15','30-03-2015']
and
[1236,3000,3054,4000]
Please guide me how I can perform this task.
PS: I am working of view page of codeigniter.
I'm getting the first thing as:
<?php
$usd=$this->db->query('select transaction_date, SUM(amount) as total
from transactions GROUP BY transaction_date')->result_array();
$str = '';
for($i=0; $i<count($usd); $i++){
if($i!=0){
$str = $str.', ['.date('d-m-y', strtotime($usd[$i]["transaction_date"])).', '.$usd[$i]["total"].']';
}else{
$str = $str.'['.date('d-m-y', strtotime($usd[$i]["transaction_date"])).', '.$usd[$i]["total"].']';
}
}
echo $str;
?>
Try this..
$date = '';
$total = '';
for($i=0; $i<count($usd); $i++){
if($i!=0){
$date .= date('d-m-y', strtotime($usd[$i]["transaction_date"])).', ';
$total .= $usd[$i]["total"].', ';
}else{
$date .= date('d-m-y', strtotime($usd[$i]["transaction_date"])).', ';
$total .= $usd[$i]["total"].', ';
}
}
echo $finaldate='['. $date.']';
echo $finaltotal='['. $total.']';
I don't see any reason why you need to save this data from your db in a string. Just save it in an array and it is that easy:
So here I save your data in an array, so that you get this structure:
array(
array(25-03-15, 1236),
array(26-03-15, 3000),
array(27-03-15, 3054),
array(30-03-15, 4000)
)
The you can simply use array_column() to extract the single columns, like this:
<?php
$usd = $this->db->query('select transaction_date, SUM(amount) as total
from transactions GROUP BY transaction_date')->result_array();
foreach($usd as $k => $v)
$result[] = [date('d-m-y', strtotime($usd[$k]["transaction_date"])), $usd[$k]["total"]];
$partOne = array_column($result, 0);
$partTwo = array_column($result, 1);
?>
Also if you then need this data in a string as you said in the comments you can simply transform it:
I will pass this extracted data to a graph that accepts this kind of data – Shahid Rafiq 6 mins ago
Just use this:
echo $str = "[" . implode("],[", array_map(function($v){
return implode(",", $v);
}, $usd)) . "]";
output:
[25-03-15, 1236], [26-03-15, 3000], [27-03-15, 3054], [30-03-15, 4000]
EDIT:
If you also want the parts as string just simply do this:
$partOne = "[" . implode("],[", array_column($arr, 0)) . "]";
$partTwo = "[" . implode("],[", array_column($arr, 1)) . "]";
output:
[25-03-15],[26-03-15],[27-03-15],[30-03-15]
[1236],[3000],[3054],[4000]
From LDAP I'm querying my users and this code sets them as a variable in the quoted format I need to run the MySQL query which would be 'username','other_username', etc...
foreach ($prefs as $who => $pref) {
if (strpos($who, 'public') === false) {
$team_users_string .='\'' . $who . '\',';
}
When I try to sanitize the command with the following code it converts the string to \'username\',\'other_username\', what can I do to correct this?
$team_users = rtrim($team_users_string, ",");
$start_date = $_POST['start_year'] . '-' . $_POST['start_month'];
$end_date = $_POST['end_year'] . '-' . $_POST['end_month'];
echo 'Welcome, <strong>' . $user . '</strong><br />';
echo '<br />';
echo '<strong>Selected Start Date:</strong> ' . $start_date . '<br />';
echo '<strong>Selected End Date:</strong> ' . $end_date . '<br />';
mysql_real_escape_string($team_users),
mysql_real_escape_string($start_date),
mysql_real_escape_String($end_date));
$query = "SELECT * FROM vacation WHERE user_name in ($team_users) AND day BETWEEN '$start_date-01' AND '$end_date-31'";
Your problem is that you're adding the quote characters before you pass the string to mysql_real_escape_string(). So the literal quotes become escaped by that function.
You could avoid this by using mysql_real_escape_string(), and then delimiting the result in quotes.
Also I'd use an array and implode() the array to get commas, instead of being forced to rtrim() the last comma.
foreach ($prefs as $who => $pref) {
if (strpos($who, 'public') === false) {
$team_users_array[] = "'" . mysql_real_escape_string($who) . "'";
}
}
$team_users = implode(",", $team_users_array); // no rtrim needed
ik have a html form where i can select some options. I want to write those values comma separated to my database. This is the code i have
$genretotal = $_POST['genre'];
$genre0 = $genretotal[0];
$genre1 = $genretotal[1];
$genre2 = $genretotal[2];
$genre3 = $genretotal[3];
$genre4 = $genretotal[4];
$genre5 = $genretotal[5];
$genre6 = $genretotal[6];
$genre7 = $genretotal[7];
$genre = $genre0 . "," . $genre1 . "," . $genre2 . "," . $genre3 . "," . $genre4 . "," . $genre5 . "," . $genre6 . "," . $genre7;
How can i leave out the empty values?
Try with implode and array_filter
implode(',', array_filter($_POST['genre']));
Why so?
$genre = join(',', array_filter($_POST['genre'], function($sItem)
{
//here I assume your 'not empty' matches PHP empty() function
//if not, then add desired conditions
return !empty($sItem);
}));
$genretotal = $_POST['genre'];
if(isset($genretotal) && count($genretotal)>0)
{//This check array is null or not
$gen_arr = implode(",",$genretotal);
}//end if
echo $gen_arr;
//This is the code you avoid empty values
