How can I have same data stored as much as provided number?
Example
Store abc, 10 times
both abc and 10 are coming from form request
Code
nonuiqueAmount: 10
nonuiqueSerial: "abc"
if(!empty($request->input('nonuiqueSerial'))) {
foreach($request->input('nonuiqueAmount') as $item) { // this returns error
$barcode = new Barcode;
$barcode->serial_number = $request->input('nonuiqueSerial');
$barcode->save();
}
}
Error:
Invalid argument supplied for foreach()
You should use a for loop:
// nonuiqueAmount: 10
// nonuiqueSerial: "abc"
if (!empty($request->input('nonuiqueSerial'))) {
for ($i = 0; $i < $request->input('nonuiqueAmount', 0); ++$i) { // I've added the zero as a default value to prevent unnecessary loops
$barcode = new Barcode;
$barcode->serial_number = $request->input('nonuiqueSerial');
$barcode->save();
}
}
The foreach loop works only on arrays, and is used to loop through each key/value pair in an array. w3schools docs
Your nonuiqueAmount is an int. I would suggest simply stick with basic for loop
for ($x = 0; $x < $request->input('nonuiqueAmount'); $x++) {
$barcode = new Barcode;
$barcode->serial_number = $request->input('nonuiqueSerial');
$barcode->save();
}

I need to create a unique value for $total, to be different from all other values from received object. It should compare total with order_amount from object, and then if it is the same, it should increase its value by 0.00000001, and then check again through that object to see if it matches again with another order_amount. The end result should be a unique value, with minimal increase compared to the starting $total value. All values are set to have 8 decmal places.
I have tried with the following but it won't get me the result i need. What am i doing wrong?
function unique_amount($amount, $rate) {
$total = round($amount / $rate, 8);
$other_amounts = some object...;
foreach($other_amounts as $amount) {
if ($amount->order_amount == $total) {
$total = $total + 0.00000001;
}
}
return $total;
}
<?php
define('EPSILON',0.00000001);
$total = 4.00000000;
$other_amounts = [4.00000001,4.00000000,4.00000002];
sort($other_amounts);
foreach($other_amounts as $each_amount){
if($total === $each_amount){ // $total === $each_amount->order_amount , incase of objects
$total += EPSILON;
}
}
var_dump($total);
OUTPUT
float(4.00000003)
You may add an additional break if $total < $each_amount to make it a bit more efficient.
UPDATE
To sort objects in $other_amounts based on amount, you can use usort.
usort($other_amounts,function($o1,$o2){
if($o1->order_amount < $o2->order_amount ) return -1;
else if($o1->order_amount > $o2->order_amount ) return 1;
return 0;
});
Ok, here's the solution I came up with. First I created a function to deliver random objects with random totals so I could work with, unnecessary for you but useful for the sake of this test:
function generate_objects()
{
$outputObjects = [];
for ($i=0; $i < 100; $i++) {
$object = new \stdClass();
$mainValue = random_int(1,9);
$decimalValue = random_int(1,9);
$object->order_amount = "{$mainValue}.0000000{$decimalValue}";
$outputObjects[] = $object;
}
return $outputObjects;
}
And now for the solution part, first the code, then the explanation:
function unique_amount($amount, $rate) {
$total = number_format(round($amount / $rate, 8), 4);
$searchTotal = $total;
if (strpos((string) $searchTotal, '.') !== false) {
$searchTotal = str_replace('.', '\.', $searchTotal);
}
$other_amounts = generate_objects();
$similarTotals = [];
foreach($other_amounts as $amount) {
if (preg_match("/^$searchTotal/", $amount->order_amount)) {
$similarTotals[] = $amount->order_amount;
}
}
if (!empty($similarTotals)) {
rsort($similarTotals);
$total = ($similarTotals[0] + 0.00000001);
}
// DEBUG
//echo '<pre>';
//$vars = get_defined_vars();
//unset($vars['other_amounts']);
//print_r($vars);
//die;
return $total;
}
$test = unique_amount(8,1);
echo $test;
I decided to use RegEx to find the amounts that starts with the ones I provided. Since in the exercise I provided only integers with 1-9 in the last decimal case, I tracked them and added them to one array $similarTotals.
Then I sorted this array, if not empty, descending by the values, got the first item and incremented by 0.00000001.
So, finally, returning either the $total (assuming nothing was found) or the incremented first item in the array.
PS. I did not expect this code to be this big but, well...
You can see the test here: https://3v4l.org/WGThI
I'm having some doubt doing some for each loop, so i have an immense variable names ranging from $a1 - $a120
What I'm trying to do is doing a for each loop from where I can get each of thoose by using an indexing system.
$a116= "N69";
$a117= "V52";
$a118= "V53";
$a119= "V54";
$a120= "V55";
# FIM
for ($i = 0; $i <= 119; ++$i) {
$var = ${"a".$i}; // This is what i need to learn to do
$sheet->setCellValue($var, $array[$i]); // the array is other information im inserting to the file
}
It is not good for the loops. But you can use it, if you can not change your codes.
I just added
$var_name="a".$i;
$var = $$var_name;
And the full code is below.
$a116= "N69";
$a117= "V52";
$a118= "V53";
$a119= "V54";
$a120= "V55";
# FIM
for ($i = 0; $i <= 119; ++$i) {
$var_name="a".$i;
$var = $$var_name; // This is what i need to learn to do
$sheet->setCellValue($var, $array[$i]); // the array is other information im inserting to the file
}
You should update the code to use an array.
$data = [];
$data["a116"] = "N69";
$data["a117"] = "V52";
$data["a118"] = "V53";
$data["a119"] = "V54";
$data["a120"] = "V55";
Now you can use a foreach loop getting the key/value pairs
foreach($data as $key => $value){
$sheet->setCellValue($key, $value);
}
Hi there i have some questions, how to continuing the data while the condition has reach 500 value on the new file and then create some random number beside the sitemap name. this is my script:
$rand = rand(1,9);
$open1 = fopen("sitemap-$rand.txt", 'w');
$web = 'http://'.$_SERVER['SERVER_NAME'].'/';
$ws = $_SERVER['SERVER_NAME'];
$i = 1;
foreach ($data as $key => $value) {
$hasil = home_base_url().strtolower($value).'.html'."\n";
fwrite($open1, $hasil);
if (++$i == 500) {
break;
}
}
Thanks for your help
You mean that there are 500 lines, per random numbered sitemap?
if (++$i == 500) {
$value = rand(0,9);// set valuie to a new random value
$i = 0; // reset the counter
}
N.B.: It might be that the loop will pick the same random number twice. Either pick a larger number to decrease the odds, or create a small function which knows which names are used, so you must pick a new name.
I am looking for a PHP solution to use a loop to go through to capture all the data
Here is an example of a lookup without using a loop
if (array_key_exists('utf8String', $cert['tbsCertificate']['subject']['rdnSequence'][0][0]['value'])) {
// do somthing
} else if (array_key_exists('printableString', $cert['tbsCertificate']['subject']['rdnSequence'][0][0]['value'])) {
// do somthing
} else if (array_key_exists('bmpString', $cert['tbsCertificate']['subject']['rdnSequence'][0][0]['value'])) {
// do somthing
} else if (array_key_exists('telextexString', $cert['tbsCertificate']['subject']['rdnSequence'][0][0]['value'])) {
// do somthing
}
I need the loop to go through the entire array. For ONLY the first [ ] the loop should increase the integer [0] to 1, [2] and so forth until its gone through the whole lot. In case you are wondering, the second [ ] is always [0] so that needs to remain as is.
Right now I am copying/pasting the above about 20 times and manually updating the number in the first box but I am hoping there is a more elegant way to achieve that.
-- MORE CONTEXT --
-- WORKING CODE -- offered by #Ghost
$count = count($cert['tbsCertificate']['subject']['rdnSequence']);
$exists = array('utf8String', 'printableString', 'teletexString');
$oid = array('id-at-stateOrProvinceName', 'id-at-countryName', 'id-at-localityName', 'id-at-commonName', 'id-at-organizationalUnitName');
for($i = 0; $i < $count; $i++) {
foreach($exists as $field) {
if(array_key_exists($field, $cert['tbsCertificate']['subject']['rdnSequence'][$i][0]['value'])) {
$value = $cert['tbsCertificate']['subject']['rdnSequence'][$i][0]['value'][$field];
echo $value, ' [',$field, ']',"\n";
}
}
}
You can just add another loop inside applying each field into array_key_exists, this applies to #Markus' idea anyway:
$count = count($cert['tbsCertificate']['subject']['rdnSequence']);
$exists = array('utf8String', 'printableString', 'teletexString');
$oid = array('id-at-stateOrProvinceName', 'id-at-countryName', 'id-at-localityName', 'id-at-commonName', 'id-at-organizationalUnitName');
for($i = 0; $i < $count; $i++) {
foreach($exists as $field) {
if(array_key_exists($field, $cert['tbsCertificate']['subject']['rdnSequence'][$i][0]['value'])) {
$value = $cert['tbsCertificate']['subject']['rdnSequence'][$i][0]['value'][$field];
$k = array_keys($cert['tbsCertificate']['subject']['rdnSequence'][$i][0]['type']);
$oid = reset($k);
break;
}
}
}
[ EDIT: Please see the comments below. ] How about for simples...
$strings = ['utf8String', 'printableString' ... ];
foreach ($strings as $string) { // do your checks etc. }
I suppose you know how to increment a counter in a loop. $i++ and stuff, use [$i] wherever you need to increment the reference value in your $cert array. On match, break or continue in place of else if, depending on what exactly you need to accomplish here. Your objectives aren't too clear in the question, could share a bit more insight...
I'm using json_decode to parse JSON files. In a for loop, I attempt to capture specific cases in the JSON in which one element or another exist. I've implemented a function that seems to fit my needs, but I find that I need to use two for loops to get it to catch both of my cases.
I would rather use a single loop, if that's possible, but I'm stuck on how to get both cases caught in a single pass. Here's a mockup of what I would like the result to look like:
<?php
function extract($thisfile){
$test = implode("", file($thisfile));
$obj = json_decode($test, true);
for ($i = 0; $i <= sizeof($obj['patcher']['boxes']); $i ++) {
//this is sometimes found 2nd
if ($obj['patcher']['boxes'][$i]['box']['name'] == "mystring1") {
}
//this is sometimes found 1st
if ($obj['patcher']['boxes'][$i]['box']['name'] == "mystring2") {
}
}
}
?>
Can anyone tell me how I could catch both cases outlined above within a single iteration?
I clearly could not do something like
if ($obj['patcher']['boxes'][$i]['box']['name'] == "string1" && $obj['patcher']['boxes'][$i]['box']['name'] == "string2") {}
...because that condition would never be met.
Generally what I do when I have raw data that is in an order that isn't ideal to work with is to run a first loop pass to generate a a list of indexes for me to pass through a second time.
So a quick example from your code:
<?php
function extract($thisfile){
$test = implode("", file($thisfile));
$obj = json_decode($test, true);
$index_mystring2 = array(); //Your list of indexes for the second condition
//1st loop.
$box_name;
for ($i = 0; $i <= sizeof($obj['patcher']['boxes']); $i ++) {
$box_name = $obj['patcher']['boxes'][$i]['box']['name'];
if ( $box_name == "mystring1") {
//Do your code here for condition 1
}
if ($box_name == "mystring2") {
//We push the index onto an array for a later loop.
array_push($index_mystring2, $i);
}
}
//2nd loop
for($j=0; $j<=sizeof($index_mystring2); $j++) {
//Your code here. do note that $obj['patcher']['boxes'][$j]
// will refer you to the data in your decoded json tree
}
}
?>
Granted you can do this in more generic ways so it's cleaner (ie, generate both the first and second conditions into indexes) but i think you get the idea :)
I found that something like what #Jon had mentioned is probably the best way to attack this problem, for me at least:
<?php
function extract($thisfile){
$test = implode("", file($thisfile));
$obj = json_decode($test, true);
$found1 = $found2 = false;
for ($i = 0; $i <= sizeof($obj['patcher']['boxes']); $i ++) {
//this is sometimes found 2nd
if ($obj['patcher']['boxes'][$i]['box']['name'] == "mystring1") {
$found1 = true;
}
//this is sometimes found 1st
if ($obj['patcher']['boxes'][$i]['box']['name'] == "mystring2") {
$found2 = true;
}
if ($found1 && $found2){
break;
}
}
}
?>
