Are there restrictions on PHP functions I can use in PHP customizations?
Environment:
All PHP/CPHP customizations, Process Designer, Custom Process Model (CPM)
May 2012 version and newer
Issue:
We are implementing a customization using PHP, and a standard function is not working.
Cause:
Several standard PHP functions are excluded from use in customizations using PHP/CPHP.
chmod()
chown()
dl()
exec()
filter_var()
fsockopen()
getmypid()
hash_hmac()
ini_set()
lchgrp()
lchown()
link()
mb_substr()
passthru()
proc_open()
readfile()
shell_exec()
simplexml_load_string()
symlink()
system()
Some protocols, including SFTP, are disabled for use in cURL. You would see the error message "Protocol […] not supported or disabled in libcurl."
Resolution:
These functions cannot be enabled. An alternative coding approach must be used.
