How PHP optimizes your code

1. Using Zend Optimizer
Method is added in php.ini
Zend_optimization_level=15
zned_extendsion= "Path/to/zendoptimizer.so"
Zend_loader.enable=off


Note that you can turn zend_loader off only when it's not Zend Enocder Runtime.


The last line works: The Zend_loader can be slightly faster to opimizer without executing.


2. Using the cache (program size is large)
Zend cache, Afterburner cache, APC


3. Page compression content
Gzip Compressed Web pages


4. Tips:
Replace i = i+1 with I +=1;
Use PHP intrinsic functions whenever possible
Use single-quote strings whenever possible with single-quote strings
foreach instead of while traversal array

Database aspects:
Improve the performance of your database
Upgrade servers or build a load-balanced environment
Do not underestimate the role of content compression
