Using <?= instead of echo in PHP (Laravel 5)?

This question already has an answer here: PHP echo vs PHP short tags 7 answers What does '<?=' mean in PHP? 8 answers The <?= $var; ?> <?= $var; ?> is a short tag and is available for some time. In MVC's it is quite common to use and it is not bad, but not always the right choice. Some servers doesn't allow short tags at all. You can change this settings

在PHP中使用<?=而不是echo(Laravel 5)?

这个问题在这里已经有了答案: PHP回声vs PHP短标签7个答案 在PHP中'<= ='是什么意思? 8个答案 <?= $var; ?> <?= $var; ?>是一个短标签,并且可用一段时间。 在MVC中,它的使用非常普遍,并且不错,但并不总是正确的选择。 有些服务器根本不允许使用短标签。 您可以通过在.htaccess中启用它来更改此设置,但在尝试之前,您无法确定它会起作用。 <IfModule mod_php5.c> php_value sho

Safely concatenate multibyte strings

I'm looking increasingly into ensuring that PHP apps are multibyte-safe, which mostly involves replacing string manipulation functions with their equivilant mb_* functions. However string concatenation is giving me pause for thought. Some character encodings (such as UTF-16 unicode) can include a Byte Order Mark at the beginning. If you concatenated two UTF16 strings it's possible yo

安全地连接多字节字符串

我越来越注意确保PHP应用程序是多字节安全的,这主要涉及用它们的equivilant mb_ *函数替换字符串操作函数。 然而字符串连接让我暂停思考。 一些字符编码(例如UTF-16 unicode)可以在开始时包含一个字节顺序标记。 如果将两个UTF16字符串连接起来,则可以在开始位置以外的位置将结果字符串引入结果字符串中。 我怀疑还有其他的编码也可以包含“标题”信息,例如将两个相同编码的字符串拼接在一起也是有问题的。 在执行多字

PHP convert unicode spaces to ascii spaces

So I'm having a problem where I believe what's happening is I'm receiving data that uses some unicode spaces and some ascii spaces, such that certain strings that appear the same are not equivalent, for example, "water resistant" != "water resistant". These strings appear differently in my database, however, with the weird characters you normally see when there

PHP将unicode空间转换为ascii空格

所以我遇到了一个问题,我相信发生了什么是我收到的数据使用了一些unicode空间和一些ascii空格,因此某些显示相同的字符串并不等同,例如“防水”!=“防水”。 这些字符串在我的数据库中的显示方式不同,但是,当您有多字节字符时,通常会看到奇怪的字符:“防水”和“防水”。 我想要一种使所有空格成为ASCII空格的方法,或者如果更简单,所有空格都是多字节空格。 我试过使用preg_replace,但随后字符串不再像有效的多字节字符串

replace be safely used on a UTF

PHP's str_replace() was intended only for ANSI strings and as such can mangle UTF-8 strings. However, given that it's binary-safe would it work properly if it was only given valid UTF-8 strings as arguments? Edit: I'm not looking for a replacement function, I would just like to know if this hypothesis is correct. Yes. UTF-8 is deliberately designed to allow this and other simila

替换可以安全地用于UTF

PHP的str_replace()仅适用于ANSI字符串,因此可能会破坏UTF-8字符串。 但是,如果它只有被赋予有效的UTF-8字符串作为参数,那么鉴于它是二进制安全的,它是否能够正常工作? 编辑:我不是在寻找替代函数,我只想知道这个假设是否正确。 是。 UTF-8被有意设计为允许这种和其他类似的非Unicode感知处理。 在UTF-8中,任何表示有效字符的非ASCII字节序列始终以范围xC0-xFF中的一个字节开头。 该字节可能不会出现在序列中的

String corrupted or preg

The NO-BREAK SPACE and many other UTF-8 symbols need 2 bytes to its representation; so, in a supposed context of UTF8 strings, an isolated (not preceded by xC2) byte of non-ASCII (>127) is a non-recognized character... Ok, it is only a layout problem (!), but it corrupts the whole string? How to avoid this "non-expected behaviour"? (it occurs in some functions and not in others).

字符串损坏或preg

NO-BREAK SPACE和许多其他UTF-8符号需要2个字节来表示; 因此,在UTF8字符串的假定上下文中,非ASCII(> 127)的隔离(不是xC2)字节是未识别的字符...好吧,它只是一个布局问题(!),但它腐败整个字符串? 如何避免这种“非预期行为”? (它发生在一些功能中,而不是其他功能中)。 示例(仅使用preg_match生成非预期行为): header("Content-Type: text/plain; charset=utf-8"); // same if text/html //PHP Ver

Matching Unicode letter characters in PCRE/PHP

I'm trying to write a reasonably permissive validator for names in PHP, and my first attempt consists of the following pattern: // unicode letters, apostrophe, hyphen, space $namePattern = "/^([\p{L}'\- ])+$/"; This is eventually passed to a call to preg_match() . As far as I can tell, this works with your vanilla ASCII alphabet, but seems to trip up on spicier characters like Ă or 张. I

在PCRE / PHP中匹配Unicode字母字符

我试图为PHP中的名称编写一个合理的宽容验证器,并且我的第一次尝试包含以下模式: // unicode letters, apostrophe, hyphen, space $namePattern = "/^([\p{L}'\- ])+$/"; 这最终传递给对preg_match()的调用。 据我所知,这可以与你的香草ASCII字母表一起使用,但似乎在sp或张这些更为尖刻的字符上出现。 模式本身有问题吗? 也许我希望p{L}做更多的工作,而不是我认为的那样? 或者它与输入传入的方式有关? 我不确定
