ps_delete(PECL ps:1.1.0-1.3.5) ps_delete — Deletes all resources of a PostScript document 说明
bool ps_delete
( resource $psdoc
)
Mainly frees memory used by the document. Also closes a file, if it was not closed before with ps_close(). You should in any case close the file with ps_close() before, because ps_close() not just closes the file but also outputs a trailor containing PostScript comments like the number of pages in the document and adding the bookmark hierarchy. 返回值如果成功则返回 TRUE,失败则返回 FALSE。 |
