This article explains the importance of URL encoding for transmitting special and non-ASCII characters, demonstrates how to use PHP's urlencode function with example code for both English and Chinese strings, and notes the difference with rawurlencode for space handling.
This article explains the importance of URL encoding for transmitting data safely on the internet, demonstrates how to use PHP's built‑in urlencode function with examples for both ASCII and non‑ASCII strings, and highlights considerations such as space handling and the alternative rawurlencode function.
Baidu built a high‑availability, low‑latency distributed transmission system that connects directly to global securities exchanges via dedicated optical lines and multicast support, synchronizes data across multiple cloud regions, provides Internet fallback for disaster recovery, and delivers sub‑60 ms market data to billions of daily financial service requests with five‑nine reliability.
