Fatal error on file_put_contents() NOT related memory_limt, execution time, input_time in phpQuestion: I get one php script, csvextract.php, as attached in code area, and I found the error message
"Fatal Error: Out of memory(allocated 3123000)(tried to allocate 71 bytes) in /home/.../csvextract.php line 17"
at the line 17 is exactly at file_put contents() function location.
And I already check my php.ini file and .htaccess file, those are already setting correct memory_limit=128M,
max_execution_time=0, max_input_time=-1, so I believe the error message is NOT related to
memory_limit, max_input_time, max_exexcution_time.
SO what other factors or setting in php.ini will affect the file_put_contents() function ? Is the fatal error
related to magic_quotes_sysbase() and magic_quotes_runtime() ? I got confused about how to use
magic_quotes_sysbase!
When I cut down the file of "data.csv" file size by half or number of row in the file by half,
it is passed and no any error message.So I suspect $csv variable to store the array from file() can NOT
be too much size. Do you think so.? Is there any setting in php.ini related to parsing variable size like $csv as follows
Be reminded my fatal error message is out of memory(allocated 3123000)(tried) and NOT "Allowed memory size 100k exhausted"
If memory_limit is not set correctly, it will report error like " Allowed memory size 100k exhausted" for example only
Please advise

I can't go into the line http://ar.php.net.manual/en/function.forgets.php , Why it is empty?
Author: duncanb7 replied at 2024-05-17 17:07:05
$new_csv[$a] = implode(',', $line);
Try the new variavel of $new_csv
nad file_put_contents("data.csv", $new_csv);
But all is same to get the same error message

I don't know if the above tip will solve your memory problem, but in any case:
- Avoid loading and writing big data files with shortcuts methods such as file, file_get_contents and file_put_contents, since they take the whole lot of data in and out of memory before each operation. Instead, build and write your data one line at a time, see http://ar.php.net/manual/en/function.fgets.php
- I think setting post_max_size through ini_set is useless, since POST header parsing is already done by the time your PHP script starts

You have a bug in line 19.
You're destroying the CSV array you're trying to modify by imploding the line back into CSV format.
Try this:

Try this:
Anyway, it is not advisable to modifiy the same array you're iterating. Better yet:
$new_csv=array();for ($i = 0; $i < $e; $i++) { ... $new_csv[$a] = implode(',', $line);} 1:2:3:4:5:
