    opcache_compile_file — Compiles and caches a PHP script without executing it

    Descripción

    opcache_compile_file(string $filename): bool

    This function compiles a PHP script and adds it to the opcode cache without executing it. This can be used to prime the cache after a Web server restart by pre-caching files that will be included in later requests.

    Parámetros

    filename

    The path to the PHP script to be compiled.

    Valores devueltos

    Returns true if filename was compiled successfully o false en caso de error.

    Errores/Excepciones

    If filename cannot be loaded or compiled, an error of level E_WARNING is generated. You may use @ to suppress this warning.

    Be aware that opcache will only compile and cache files older than the script execution start.

    For instance, if you use a script to generate cache files (e.g. you don't have access to shmop and rely on opcache for in-memory data caching instead), opcache_compile_file will not include the generated file in the cache, because its modification time is after the script start.

    The workaround is to use touch() to set a date before the script execution date, then opcache will compile and cache the generated file.
