To create a comma-separated list from an array in PHP, the code is as follows−
Example
<?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";
}
?>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
Example
Let us now see another example −
<?php
$arr = array(100, 200, 300, 400, 500);
echo "Comma separated list...\n";
print_r(implode(', ', $arr));
?>Output
This will produce the following output−
Comma separated list... 100, 200, 300, 400, 500
