Foreach with Three Variables Add

Php foreach sorting with three variables

Code :

<?php
  error_reporting('E_ALL');

  $a = Array(Array("Los Angeles","City","los-angeles"),Array("San Francisco","City","san-francisco"),Array("San Diego","City","san-diego"),Array("United States","Country","united-states"));

  foreach ($a as $key => $value) {
      $return[$value[1]][] = array("name"=>$value[0],"slug"=>$value[2]);
  }   

  foreach ($return as $key => $value) {
    echo $key.":";
      foreach($value as $newvalue){
       echo '<span class="tags"><a href="'.$newvalue["slug"].'">'.$newvalue["name"].'</a> </span>';
    }
    echo "<br>";
  }

Output:

City:<span class="tags"></span><a href="los-angeles">Los Angeles</a> <span class="tags"></span><a href="san-francisco">San Francisco</a> <span class="tags"></span><a href="san-diego">San Diego</a> <br>Country:<span class="tags"></span><a href="united-states">United States</a> <br>

Multiple index variables in PHP foreach loop

to achieve just that result you could do

foreach (array_combine($courses, $sections) as $course => $section)

but that only works for two arrays

foreach loop with 3 variables

An example of how to do it:

$a = 'file1.txt';
$b = 'file2.txt';
$c = 'file3.txt';

$a1 = explode("\r\n", file_get_contents($a));
$b1 = explode("\r\n", file_get_contents($b));
$c1 = explode("\r\n", file_get_contents($c));

for($id = 1; $id <= 3; $id++) {
    $line = $id - 1;
    echo "id: {$id} lang1: {$a1[$line]} lang2 {$b1[$line]} lang3: {$c1[$line]} <br>"; 
}

Foreach multiple variables

Maybe this will do the trick.

function get_order_item_lines($skus = '', $qty = '')
{
    $xml = '';

    if (!empty($skus) && is_array($skus))
    {
        foreach ($skus as $key => $sku)
        {
            $skuUpper = strtoupper($sku); // change to upper
            
            if ($skuUpper != 'WANHAO-STICKER'
                && strpos($skuUpper, 'NWS-', 0) === false)  // string not contains..
            {
                $xml .= "<L>".PHP_EOL;
                $xml .= "<P>" . $sku . "</P>".PHP_EOL;
                $xml .= "<Q>" . (empty($qty[$key]) ? "" : $qty[$key]) . "</Q>".PHP_EOL;
                $xml .= "</L>".PHP_EOL;
            }
        }
    } 
    else 
    {
        $skus = explode( ",", $skus );

        if ( !empty( $skus[0] ) && !empty( $qty[0] ) ) 
        {
            $skuUpper = strtoupper($skus[0]); // change to upper
            
            if ($skuUpper != 'WANHAO-STICKER'
                && strpos($skuUpper, 'NWS-', 0) === false)
            {
                $xml .= "<L>".PHP_EOL;
                $xml .= "<P>" . trim( $skus[0] ) . "</P>".PHP_EOL;
                $xml .= "<Q>" . (empty($qty[0]) ? "" : $qty[0]) . "</Q>".PHP_EOL;
                $xml .= "</L>".PHP_EOL;
            }
        }
    }

    return $xml;
}

Add value into three different variables from Foreach-Object

PowerShell learned from Perl and Python, so you can do this:

$FTP_HOST, $FTP_USER, $FTP_PASS = (Get-Content .\config.cfg) -split ':'

Multiple variable pass in one Foreach loop in laravel blade

For merge and combine array , you can try :

$array = array_merge($array1,$array2);

Example in blade :

@foreach(array_merge($array1,$array2) as $item)
    // ...
@endforeach

---

Another Example :

@foreach($array1 as $key => $row)
    <li>
        <b>{{ $row['id'] }}</b>
        <p>{{ $array2[$key]->payment }}</p>
    </li>
@endforeach
