php - Writing/Reading & Permissions -


another dev , creating website , using php read/write to/from our site's directory. reason, on end works fine can 1 type of i/o work... if modify httpd.conf file , change user: 

user _www        //change system user name (spencer) group _www

i can upload image files our directory, make change, can no longer read text files causes exception:

uncaught syntaxerror: unexpected token <

on line: 

var results = $.parsejson(data);

if me better understand relevant portion of httpd.conf file included above , me direction improving setup, appreciative!

edit:

when add console.log(data) before json parse, output <b>warning</b>: chmod(): operation not permitted in <b>/users/spencer/programming/... , error contains text of file i'm trying open..

after digging more, turns out causing problem: chmod($filename, 0777); , guess problem because php user , system user clash. found info php , chmod() function here

removed irrelevant code
