Removing Array Element and Re-Indexing in PHP

To remove an array element and re-index the array, the code is as follows−

Example

 Live Demo

<?php
   $arr = array( " John ", "Jacob ", " Tom ", " Tim ");
   echo "Array with leading and trailing whitespaces...
";
   foreach( $arr as $value ) {
      echo "Value = $value 
";
   }
   echo "\nComma separated list...
";
   print_r(implode(', ', $arr));
   $result = array_map('trim', $arr);
   echo "\nUpdated Array...
";
   foreach( $result as $value ) {
      echo "Value = $value 
";
   }
   unset($result[1]);
   echo "\nUpdated Array...Re-indexed
";
   $result2 = array_values($result);
   foreach( $result2 as $value ) {
      echo "Value = $value 
";
   }
?>

Output

This will produce the following output−

Array with leading and trailing whitespaces...
Value = John
Value = Jacob
Value = Tom
Value = Tim
Comma separated list...
John , Jacob , Tom , Tim
Updated Array...
Value = John
Value = Jacob
Value = Tom
Value = Tim
Updated Array...Re-indexed
Value = John
Value = Tom
Value = Tim
