PHP में एरे को री-इंडेक्स कैसे करें?

PHP में एरे को री-इंडेक्स करने के लिए, कोड इस प्रकार है:

उदाहरण: न्यूमेरिक कीज़ री-इंडेक्स

<?php
$arr = array(
    0 => "150",
    1 => "100",
    2 => "120",
    3 => "110",
    4 => "115"
);
echo "Array...\n";
foreach ($arr as $key => $value) {
    echo " Key = " . $key . ", Value = " . $value . "\n";
}
$arr = array_combine(range(2, count($arr) + 1), array_values($arr));
echo "\nArray after re-indexing\n";
foreach ($arr as $key => $value) {
    echo " Key = " . $key . ", Value = " . $value . "\n";
}
?>

आउटपुट

Array...
Key = 0, Value = 150
Key = 1, Value = 100
Key = 2, Value = 120
Key = 3, Value = 110
Key = 4, Value = 115
Array after re-indexing
Key = 2, Value = 150
Key = 3, Value = 100
Key = 4, Value = 120
Key = 5, Value = 110
Key = 6, Value = 115

उदाहरण: स्ट्रिंग कीज़ री-इंडेक्स

<?php
$arr = array(
    "a" => "150",
    "b" => "100",
    "c" => "120",
    "d" => "110",
    "e" => "115"
);
echo "Array...\n";
foreach ($arr as $key => $value) {
    echo " Key = " . $key . ", Value = " . $value . "\n";
}
$arr = array_combine(range("b", chr(count($arr) + (ord("b") - 1))), array_values($arr));
echo "\nArray after re-indexing\n";
foreach ($arr as $key => $value) {
    echo " Key = " . $key . ", Value = " . $value . "\n";
}
?>

आउटपुट

Array...
Key = a, Value = 150
Key = b, Value = 100
Key = c, Value = 120
Key = d, Value = 110
Key = e, Value = 115
Array after re-indexing
Key = b, Value = 150
Key = c, Value = 100
Key = d, Value = 120
Key = e, Value = 110
Key = f, Value = 115
