Introduction to php document update_PHP tutorial
The simple trial experience is as follows:
Install pman
Use the legendary pear to install pman
sudo pear install doc.php.net/pman
If the pear version is older, you need to upgrade it first pear before you can continue
sudo pear upgrade pear
How to use pman
The way to use pman is very stupid. For example, we want to view the help information of strlen:
pman strlen
The content of the help text is in color, comparable to the chm version of the php help document. The detailed usage help of pman is as follows
#pman --help
man, version 1.6c
usage: man [-adfhktwW] [section] [-M path] [-P pager] [-S list]
[-m system] [-p string] name ...
a : find all matching entries
c : do not use cat file
d : print gobs of debugging information
D : as for -d, but also display the pages
f : same as whatis(1)
h : print this help message
k : same as apropos(1)
K : search for a string in all pages
t : use troff to format pages for printing
w : print location of man page(s) that would be displayed
(if no name given: print directories that would be searched)
W : as for -w, but display filenames only
C file : use `file' as configuration file
M path : set search path for manual pages to `path'
P pager : use program `pager' to display pages
S list : colon separated section list
m system : search for alternate system's man pages
p string : string tells which preprocessors to run
e - [n]eqn( 1) p - pic(1) t - tbl(1)
g - grap(1) r - refer(1) v - vgrind(1)
Another advantage is that It is more convenient to view php help information in vim, and the combination is perfect
:!pman strlen

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
