如何在PHP中从数组中创建逗号分隔的列表

要从PHP中的数组创建以逗号分隔的列表，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"; } echo "\n逗号分隔列表...\n"; print_r(implode(, , $arr)); $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 逗号分隔列表... John , Jacob , Tom , 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(100, 200, 300, 400, 500); echo "逗号分隔列表...\n"; print_r(implode(, , $arr)); ?>

输出结果

逗号分隔列表... 100, 200, 300, 400, 500
