正则零宽断言

https://blog.csdn.net/u010801439/article/details/77921037

零宽断言表示匹配字符的时候再添加一些定位条件，使匹配更精准。

  • \w+(?=ing) 匹配以ing结尾的多个字符（不包括ing）
  • \w+(?!ing) 匹配不是以ing结尾的多个字符
  • (?<=re)\w+ 匹配以re开头的多个字符（不包括re）
  • (?<!re)\w+ 匹配不是以re开头的多个字符
  • (?<=\s)\d+(?=\s) 匹配两边是空白符的数字，不包括空白符

openssl_private_encrypt 最大只能加密117字符😂

On my PHP5 build, the limit is 117 characters (936 bits, strange number). That’s because public key encryption is CPU intensive, and meant to be used on short values. The idea is to use this function to encrypt a secret key that is in turn used to encrypt data using a more efficient algorithm, such as RC4 or TripleDES.openssl_public_encrypt

blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];

FORBIDDEN/12/index read-only / allow delete (api)

官方解决方法：

curl -XPUT -H "Content-Type: application/json" http://127.0.0.1:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

_all 可以改为自己的索引名称，也可以直接执行

curl -XPUT -H "Content-Type: application/json" http://127.0.0.1:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

根据需求定制 红色部分是你要修改的部分

PHP7 扩展Hello world 

[root@local2 ext]# ./ext_skel --extname=Hello

Creating directory Hello
Creating basic files: config.m4 config.w32 .gitignore Hello.c php_Hello.h CREDITS EXPERIMENTAL tests/001.phpt Hello.php [done].

To use your new extension, you will have to execute the following steps:

1.  $ cd ..
2.  $ vi ext/Hello/config.m4
3.  $ ./buildconf
4.  $ ./configure --[with|enable]-Hello
5.  $ make
6.  $ ./sapi/cli/php -f ext/Hello/Hello.php
7.  $ vi ext/Hello/Hello.c
8.  $ make

Repeat steps 3-6 until you are satisfied with ext/Hello/config.m4 and
step 6 confirms that your module is compiled into PHP. Then, start writing
code and repeat the last two steps as often as necessary.

[root@local2 ext]# 

# phpize 
# ./configure --enable-Hello
# make
# php -i | grep Hello
# php Hello.php
