PHP में एरे के सभी स्ट्रिंग्स को ट्रिम करने के लिए, कोड इस प्रकार है:
उदाहरण: array_map('trim')
<?php
$arr = array(" John ", "Jacob ", " Tom ", " Tim ");
echo "Array with leading and trailing whitespaces...\n";
foreach ($arr as $value) {
echo "Value = $value \n";
}
$result = array_map('trim', $arr);
echo "\nUpdated Array...\n";
foreach ($result as $value) {
echo "Value = $value \n";
}
?>
आउटपुट
Array with leading and trailing whitespaces...
Value = John
Value = Jacob
Value = Tom
Value = Tim
Updated Array...
Value = John
Value = Jacob
Value = Tom
Value = Tim
उदाहरण: array_walk के साथ create_function
<?php
$arr = array(" Kevin ", "Katie ", " Angelina ", " Jack ");
echo "Array with leading and trailing whitespaces...\n";
foreach ($arr as $value) {
echo "Value = $value \n";
}
array_walk($arr, create_function('&$val', '$val = trim($val);'));
echo "\nUpdated Array...\n";
foreach ($arr as $key => $value)
print($arr[$key] . "\n");
?>
आउटपुट
Array with leading and trailing whitespaces...
Value = Kevin
Value = Katie
Value = Angelina
Value = Jack
Updated Array...
Kevin
Katie
Angelina
Jack
