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...\n";
foreach( $arr as $value ) {
echo "Value = $value \n";
}
echo "\nComma separated list...\n";
print_r(implode(', ', $arr));
$result = array_map('trim', $arr);
echo "\nUpdated Array...\n";
foreach( $result as $value ) {
echo "Value = $value \n";
}
unset($result[1]);
echo "\nUpdated Array...Re-indexed\n";
$result2 = array_values($result);
foreach( $result2 as $value ) {
echo "Value = $value \n";
}
?>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
