title: "php --help" results in "PHP memory exhausted" error on Ubuntu
body: <p>PHP Fatal error:  Allowed memory size of 262144 bytes exhausted (tried to allocate 523800 bytes) in Unknown on line 0</p>
  
  <p>Same thing occurs with "php5 --help"</p>
  
  <p>I have already researched this and read that I should:
  1) increase the memory limit in php.ini - it's at 128MB in all instances of php.ini - should be enough to run php cli help
  2) make the script more memory efficient - obviously doesn't apply to --help</p>
  
  <p>Please help if you can ?</p>
