PHP में किसी सरणी को पुन:अनुक्रमित कैसे करें?

PHP में किसी सरणी को पुन:अनुक्रमित करने के लिए, कोड इस प्रकार है -

उदाहरण

<?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

यह निम्नलिखित आउटपुट उत्पन्न करेगा-

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

आइए अब एक और उदाहरण देखें -

<?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

यह निम्नलिखित आउटपुट उत्पन्न करेगा-

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
