PHP 删除数组中所有字符串元素的空格
要修剪PHP中数组中的所有字符串，代码如下-
示例
<?php
$arr = array( " John ", "Jacob ", " Tom ", " Tim ");
echo "具有前导和尾随空格的数组...\n";
foreach( $arr as $value ) {
echo "Value = $value \n";
}
$result = array_map('trim', $arr);
echo "\n更新后的数组 ...\n";
foreach( $result as $value ) {
echo "Value = $value \n";
}
?>输出结果
具有前导和尾随空格的数组... Value = John Value = Jacob Value = Tom Value = Tim 更新后的数组 ... Value = John Value = Jacob Value = Tom Value = Tim
示例
现在让我们来看另一个示例-
<?php
$arr = array( " Kevin ", "Katie ", " Angelina ", " Jack ");
echo "具有前导和尾随空格的数组...\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");
?>输出结果
具有前导和尾随空格的数组... Value = Kevin Value = Katie Value = Angelina Value = Jack 更新后的数组 ... Kevin Katie Angelina Jack
