php里对redis的非空集合执行spop命令返回false
对同一个集合,执行$redis->scard( 'set:name' );结果是6W多。
但是对这个集合执行$redis->spop( 'set:name' );就返回false了。
集合名应该没有写错,因为代码运行了一段时间是正常的,突然之间就这样了。
请问有人遇到过相似的问题吗,如何解决?
<code>echo $redis->SCARD( 'news:id:needCrawlComment' ) . PHP_EOL; echo $redis->SRANDMEMBER( 'news:id:needCrawlComment' ) . PHP_EOL; var_dump( $redis->SPOP( 'news:id:needCrawlComment' ) ) . PHP_EOL; exit;</code>
输出结果
<code>60028 1166728333 bool(false)</code>

问题已解决,原因是内存超过1/2了,用sysctl vm.overcommit_memory=1
解决了

Redis plays a key role in data storage and management, and has become the core of modern applications through its multiple data structures and persistence mechanisms. 1) Redis supports data structures such as strings, lists, collections, ordered collections and hash tables, and is suitable for cache and complex business logic. 2) Through two persistence methods, RDB and AOF, Redis ensures reliable storage and rapid recovery of data.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Redis is a memory data structure storage system, mainly used as a database, cache and message broker. Its core features include single-threaded model, I/O multiplexing, persistence mechanism, replication and clustering functions. Redis is commonly used in practical applications for caching, session storage, and message queues. It can significantly improve its performance by selecting the right data structure, using pipelines and transactions, and monitoring and tuning.

AI can help optimize the use of Composer. Specific methods include: 1. Dependency management optimization: AI analyzes dependencies, recommends the best version combination, and reduces conflicts. 2. Automated code generation: AI generates composer.json files that conform to best practices. 3. Improve code quality: AI detects potential problems, provides optimization suggestions, and improves code quality. These methods are implemented through machine learning and natural language processing technologies to help developers improve efficiency and code quality.
