要在 PHP 中修剪数组中的所有字符串，代码如下 −
示例
<?php $arr = array( " John ", "Jacob ", " Tom ", " Tim "); echo "带有前导和尾随空格的数组......
"; foreach( $arr as $value ) { echo "Value = $value
"; } $result = array_map('trim', $arr); echo "
Updated Array...
"; foreach( $result as $value ) { echo "Value = $value
"; } ?>
输出
这将产生以下输出−
带有前导和尾随空格的数组...... Value = John Value = Jacob Value = Tom Value = Tim Updated Array... Value = John Value = Jacob Value = Tom Value = Tim
示例
现在让我们看另一个例子 −
<?php $arr = array( " Kevin ", "Katie ", " Angelina ", " Jack "); echo "带有前导和尾随空格的数组......
"; foreach( $arr as $value ) { echo "Value = $value
"; } array_walk($arr, create_function('&$val', '$val = trim($val);')); echo "
Updated Array...
"; foreach($arr as $key => $value) print($arr[$key] . "
"); ?>
输出
这将产生以下输出−
带有前导和尾随空格的数组...... Value = Kevin Value = Katie Value = Angelina Value = Jack Updated Array... Kevin Katie Angelina Jack
