php - How to: overwrite defined array with new POSTED data -


i'll redefine old unanswered & messy question 'cause i'm begging help. anyone...

i have line inside file (choices.php) has:

some choice1...||other choice2...||some data here...||overwrite me! old!

on other page there button post (and store/save) new data choices.php. newdata have overwrite text ($arrkey[3])

i tried explode / implode, file_put_contents, i've found browsing answers. far newdata being added @ end of line:

some choice1...||other choice2...||some data here...||overwrite me! old!i'm new data!

instead of:

some choice1...||other choice2...||some data here...||i'm new data!

if got question right, following code want :

$entries = explode('||', file_get_contents('choices.php')); $entries[3] = $_post['myfield']; // may want more strict checking before that. file_put_contents('choices.php', implode('||', $entries));

and, way, choices.php bad name, since file doesn't contain php code. it's won't prevent script working.
