Then write this string as a line to your file. This way you can easily read with file() which will put the file into an array of lines. Then just unpack() each line, and you have your original array back. Something like this : $arr = array( array ( 1531412763, 1439959339 ), arra...

既然我们已经了解了PHP如何分配和释放内存,接下来可以探讨一下PHP是如何处理php://filter/字符串的。我们很幸运,这里无需深入了解内部PHP结构,例如zval、zend_string、zend_array等。 为了处理过滤器,PHP首先会获取流(即读取资源)。它将流存储在一系列桶中,这些桶是双向链接的结构,每个桶包含一定大小的缓冲区。以我...
