PHP में एक सरणी में सभी स्ट्रिंग्स को ट्रिम करने के लिए, कोड इस प्रकार है-
उदाहरण
<?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
यह निम्नलिखित आउटपुट उत्पन्न करेगा-
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
आइए अब एक और उदाहरण देखें -
<?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
यह निम्नलिखित आउटपुट उत्पन्न करेगा-
Array with leading and trailing whitespaces... Value = Kevin Value = Katie Value = Angelina Value = Jack Updated Array... Kevin Katie Angelina Jack
