这里简单的介绍了关于php解决input输入多个空格只显示一个的问题，我们利用了chr(32)来替换成html空格符,实例代码如下：
<body>
<form id="form1" name="form1" method="post" action="">
<label for="textfield"></label>
<input type="text" name="txt" id="txt" />
<input type="submit" name="button" id="button" value="提交" />
</form>
</body>
</html>
<?php
if( $_POST )
{
$txt = $_POST['txt'];
echo $txt.'<br />';
echo str_replace(chr(32),' ',$txt);
}
