瞰赽 1. Writing to shared memory block

max size of shared memory, normally 131072 bytes

minimum size of shared memory, normally 1 byte

The PHP binary grows and consumes more memory.

Frees the memory occupied by the Hyperwave document.

This sets the maximum amount of memory in bytes that a script is allowed to allocate. This helps prevent poorly written scripts for eating up all available memory on a server. In order to use this directive you must have enabled it at compile time. So, your configure line would have included enable memory limit. Note that you have to set it to 1 if you don't want any limit for your memory.

The following example shows how to create a pdf document in memory and how to output it correctly.

蛁 This function will attempt to copy the data in the most efficient manner, using memory mapped files when possible.

Adds a string to the array. The flag duplicate specifies whether the string contents have to be copied to Zend internal memory.

Registers a new constant of type string. The string length is explicitly set to length. The specified string must reside in Zend's internal memory.

Fatal run time errors. These indicate errors that can not be recovered from, such as a memory allocation problem. Execution of the script is halted.

Returns the current value of entry name as string. Note This string is not duplicated, but instead points to internal data. Further access requires duplication to local memory.

Returns the original value of entry name as string. Note This string is not duplicated, but instead points to internal data. Further access requires duplication to local memory.
