max file size with file() ?

[aebstract]

Okay, this script:

<?php
$textData = file('array.txt');
echo "hello";
?>

 

hello is echo'd to the browser, no problems. If I change array.txt to array2.txt, it gives a white page and doesn't seem to even try to do anything.

array.txt is just under 1MB

array2.txt is just over 71MBs

 

Is there a limit on file size that can be opened? Cause I don't think it's hitting something inside and stopping, it seems to not even be attempting to look inside the file. Any other information needed for this problem?

Of course there are limits, such as the amount of available memory.

 

You should be developing and debugging php code on a system with error_reporting set to E_ALL and display_errors set to ON so that php will help you by reporting and displaying all the errors it detects.

My first piece of advice would be to turn on error reporting and/or check your php error logs. That usually reveals 99.9% of errors and should give you a better idea of why this isn't working.

 

71mb isn't all that big so can't see why it wouldn't work when you open that as oppose to your smaller file. There could be a parse error but it's doubtful. I don't think anything within the file could cause a parse error.

 

Get those errors and I'm sure we'd be able to help more.

Sorry for not running that, which was completely stupid:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 75023834 bytes) in /var/www/vhosts/outlawracing.com/httpdocs/insert.php on line 8

 

Is this something I can change or do I have to have my host change it?

[Anti-Moronic]

Yeh, you've ran out of memory. You need to change the php ini directive:

 

memory_limit

 

 

[aebstract]

Trying to locate the php.ini, waiting on a response from web host. Is there a way to force the memory_limit through a manual run script before trying to read the file?

[aebstract]

I created an .htaccess file with this:

php_value memory_limit 100M

 

and in my phpinfo() it says the memory_limit is 100M for local and 32M for master. I'm now getting a white page and no error. I can't echo anything before the read().

A far more useful solution would be to go through the file (often line-by-line) so as to only load a small portion of it into memory at any one time.  Unless there is some particular need to load 71 MB into memory every time the script is executed, I would advise against it.  I'd also echo the others' suggestion of enabling and displaying all errors during development.

I placed this at the top:

error_reporting(E_ALL);
ini_set("display_errors", 1);

 

but, with the .htaccess fix I mentioned above, I'm not getting an error just white space. I could do it one line at a time, but not too sure where to start as to write that, as right now I have a little function to do some array work so I can loop through every value and insert it in to the database. This is going to be a one time access deal, then it will be trashed and never ran again.

If you read the documentation for the memory_limit setting, you will find out where you can change it. For example, if your web host has not prevented it, you can set memory_limit in a script using an ini_set() statement.

salathe-

How would one EFFECTIVELY do this?  go through line by line..................

[aebstract]

Okay, I have my memory_limit set to 100M now, I am getting now errors but am still getting a blank white page. I have an echo statement ABOVE my file() and it isn't getting displayed either. Could something in the file be causing it to do this? If so, what would trigger such an event? Wouldn't I still get information up until the point that it causes error? The smaller file still works, the larger one is just blanking out.

I got an email from my host and he said this is the error that was being displayed:
