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
