PHP is so ubiquitous in web development, that anyone involved with websites is usually aware of the release schedule for new versions. The newest version, PHP 8.2 is scheduled for general release this November. In this post, we\u2019ll go over what\u2019s new in PHP 8.2.<\/p>\n\n\n\n

New “memory_reset_peak_usage” function<\/h2>\n\n\n\n

PHP 8.2 adds a new function named “memory_reset_peak_usage” that resets the peak memory usage returned by the memory_get_peak_usage<\/a> function. This can be helpful in applications that invokes or iterates an action multiple times, and needs to record the peak memory usage of each invocation. Without the ability to reset the memory usage with the new “memory_reset_peak_usage” function, the “memory_get_peak_usage” returns the absolute peak memory usage throughout the entire run.<\/p>\n\n\n\n

Readonly Classes<\/strong><\/h2>\n\n\n\n

Following the readonly feature in PHP 8.1 for class properties<\/a>, PHP 8.2 supports declaring an entire class as readonly.<\/p>\n\n\n\n

A class declared as readonly automatically makes all properties readonly. PHP 8.2 deprecates dynamic properties<\/a>, but readonly classes hard-fail dynamic properties with an Error exception. To summarize, a readonly property<\/strong>:<\/p>\n\n\n\n
