PHP中清除字符串所有空格程序代码

<?php
echo trim(" 空 格 ")."<br>";
echo rtrim("空   格 ")."<br>";
echo ltrim(" 空格")."<br>";
?>

$str = ” This line contains＼tliberal ＼r＼n use of   whitespace.＼n＼n”;
$str = trim($str);// 首先去掉头尾空格
$str = preg_replace(’/＼s(?=＼s)/’, ‘’, $str);// 接着去掉两个空格以上的
$str = preg_replace(’/[＼n＼r＼t]/’, ‘ ‘, $str);// 最后将非空格替换为一个空格

<?php

//需要执行的SQL语句
//单条
$sql="select id,name from tbl_user where id=1";
//多条数据
//$sql="select id,name from tbl_user";

//调用conn.php文件进行数据库操作
require('Conn.php');

//提示操作成功信息，注意：$result存在于conn.php文件中，被调用出来
if($result)
{

// $array=mysql_fetch_array($result,MYSQL_ASSOC);
 
  
 /*数据集

 $users=array();
 $i=0;
 while($row=mysql_fetch_array($result,MYSQL_ASSOC)){

   echo $row['id'].'-----------'.$row['name'].'</br>';
   $users[$i]=$row;
   $i++;

 }
  echo json_encode(array('dataList'=>$users));

 */

 /*单条数据*/

 $row=mysql_fetch_row($result,MYSQL_ASSOC);
 
 echo json_encode(array('jsonObj'=>$row));
}

mysql_free_result($result);
//释放结果
mysql_close();
//关闭连接

?>

可以将结果写成这样的数组形式：
$respon = array('UserKeyGetResponse' => array('RequestName' => $api_request_name, 'api_key_value' => $api_key_value),
'error_response' => array('code' => 'NO_ERROR', 'msg' => '获取系统参数成功'));
