测试代码:
$url = 'http://www.google.com/ig/calculator?hl=en&q=1USD=?tzs';
$str = @file_get_contents( $url );
$str = preg_replace("/[\s\v\t\r\n ]+/", "", $str);
echo "str:$str";
输出结果中,"1 631.32137Tanzanianshillings"最前面的“1”之后的那个空白字符老去不掉。
还请懂的朋友指点一下啊,谢谢!
回复讨论(解决方案)
echo htmlspecialchars($str);
实体html中不是空格,展示出来效果是空格
谢谢回复。
请问能不能在上面代码中的preg_replace的正则里面加上什么,然后能把这个看不见的空白去掉?
那就把 也替换了吧
加了一行,还是同样...
$url = 'http://www.google.com/ig/calculator?hl=en&q=1USD=?tzs';
$str = @file_get_contents( $url );
$str = preg_replace("/[\s\v\t\r\n ]+/", "", $str);
$str = preg_replace("/ /", "", $str);
echo "str:$str
";
  也是空白的HTML符号
我知道“ ”是空白符号,不知要在上面的正则里加上点什么,才能把那字符串中“1”后面的那个空白去掉
那个你复制一下就知道了,他不是一个空格符
php页面首部出现一大段注释说明,怎么找到是哪写的,
注释的内容,如下:
那个你复制一下就知道了,他不是一个空格符
版主好啊,
那个空白是确不是一个空格来的,但不知道怎么才能去掉它?
先把全部双引号改单引号再试吧
先把全部双引号改单引号再试吧
改了。还是同样,那个空白去不掉。
代码:
$url = 'http://www.google.com/ig/calculator?hl=en&q=1USD=?tzs';$str = @file_get_contents( $url );$str = preg_replace('/"/', '\'', $str);$str = preg_replace('/[\s\v\t\r\n ]+/', '', $str);$str = preg_replace('/ /', '', $str);echo "str:$str";
输出结果:
str:{lhs:'1U.S.dollar',rhs:'1 631.32137Tanzanianshillings',error:'',icc:true}
在$str = @file_get_contents( $url );下面加
$str =iconv("GBK", "UTF-8//IGNORE", $str);
加上这个,先转换一下就可以替换掉了,这是因为在接受过程有无法识别的字符,这样一转换就可以识别了
噢 ,可以了!
谢谢版主!

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
