删除特殊字符时遇到问题.我想删除除"()/.% - &"之外的所有特殊字符,因为我将该字符串设置为标题.

我编辑了原始代码(见下图):

preg_replace('/[^a-zA-Z0-9_ -%][().][\/]/s', '', $String);

但这并不是要删除特殊字符,例如:"â€","â€",","等等.

原始代码:(这有效但删除了这些字符:"()/.% - &")

preg_replace('/[^a-zA-Z0-9_ -]/s', '', $String);

我在命令批处理脚本中有关于IF ELSE的问题...

在记事本中:
代码:

:CHECKACCOUNT
if /I "%user%"=="insertusername" ( GOTO :ACCOUNT ) ELSE ( GOTO :CHECKPASSACCT )

:CHECKPASSACCT
if /I "%pass%"=="insertpassword" ( GOTO :ACCOUNT ) ELSE ( GOTO :COUNTER )

在命令:
代码:

(此时出乎意料.

完整的脚本代码:

@echo off

::SETTINGS:::::::::::::::::::::::
set filetxt =userpass.txt
set log=logfile.log
set timer=900
::set default = true
::set user = 0
::set pass = 0

$comment.animate({width: 0}, {queue:false, duration:450 }, function() { 
//$comment.css({ 'display': 'block' })
$comment.hide();
 });

它不显示动画.我想我已经把功能放错了地方.

我有问题..我尝试填写表单然后单击提交按钮然后它显示表单错误但所有这些文本框字段变为空白,可以显示表单错误.我希望它在验证之前变成相同的值.就像我不想在验证后清除/清空值.

我做了这样的事情:(在视图中)

<div class="regform">
        <div id="formleft">First Name<asterix>*</asterix></div>
        <div id="formright"><?php echo $this->Form->input('First Name', array(
                'name' => 'firstname',
                'label'=> false
            )); ?></div>
        <div id="formerror"><?php echo $this->Form->error('Customer.firstname'); ?></div>
    </div>

(在模型中):

'firstname' => array(
                    'firstname_cant_be_empty' => array(
                            'rule' => 'notEmpty',
                            'message' => 'First Name must be filled.'
                        ),
                    'firstname_must_be_alphabet' => array(
                            'rule' => '/^[a-z]{3,}$/i',
                            'message' => 'First Name is only letters. No numbers, Dotted, etc.'
                        )
                )

(在控制器中):

if ($this->request->is('Post')) {

            if ($this->Customer->save($this->request->data) && $this->Customer->validates()) {
                //debug($this->request->data);
                $this->Session->setFlash('good!');
                //$this->redirect('/');
            } else {
                $this->Session->setFlash('Fill up …

我有问题,str_replace不能替换倒数第二个单词...第一个单词正在工作然后第二个到最后一个不在数组中工作..我尝试在"chat.php？"中输入消息"ducker apple banana chicken"？ message ="然后变成这样:

输出:

"***er apple banana chicken"

badwords.txt:

duck;
apple;
banana;
chicken;
water;

chat.php

$censoredfilter = file("badwords.txt");
$censoredfilter = implode("\n", $censoredfilter);
$censoredfilter = explode(";", $censoredfilter);

$message = $_GET['message'];

for($i = 0; $i<sizeof($censoredfilter);$i++)
{
    $message = str_replace($censoredfilter[$i], "***", $message);
}

我很困惑......

像例子:

$Q1 = "hello";
$Q2 = "world";
$Q3 = "StackOverflow";

$i = 1;

while($i < 3) {
  $a = "$Q".$i; //I think this is wrong.    
  echo $a; // i tried ${$a} doesn't work =/

  $i++;
}

然后输出格式:

$Q1
$Q2
$Q3

但是没有这样的输出:hello world StackOverflow

我想$Q + $i成为$Q1回答的是:"你好"......
