从PHP中的字符串中删除单引号 [英] Removing single-quote from a string in php

问题描述

我有一个HTML表单，用户可以将文本输入到title字段中，然后用php创建一个名为title.html

I have an HTML form that a user can input text into a title field, I then have php creating an HTML file called title.html

我的问题是用户可以在html文件名中不能使用的标题字段中输入空格和撇号.我使用以下命令将空格替换为下划线:

My problem is that users can input spaces and apostrophes into the title field that can't be used in the html file name. I replaced the spaces with underscores by using:

$FileName = str_replace(" ", "_", $UserInput);

但是，我似乎无法删除单引号?我尝试使用:

However, I can't seem to remove single-quotes? I have tried using:

$FileName = preg_replace("/'/", '', $UserInput); 

但这花了test's并将其变成了test\s.html.

but this took test's and turned it into test\s.html.

推荐答案

使用当前的str_replace方法:

Using your current str_replace method:

$FileName = str_replace("'", "", $UserInput);

虽然很难看到，但第一个参数是双引号，然后是单引号和双引号.第二个参数是两个双引号，中间没有任何引号.

While it's hard to see, the first argument is a double quote followed by a single quote followed by a double quote. The second argument is two double quotes with nothing in between.

使用str_replace，您甚至可以拥有要完全删除的字符串数组:

With str_replace, you could even have an array of strings you want to remove entirely:

$remove[] = "'";
$remove[] = '"';
$remove[] = "-"; // just as another example

$FileName = str_replace( $remove, "", $UserInput );
