I am using PHP 4.3.5. I am having a problem in which my script is
crashing when it is using a large array. I have simplified the
problem down to the following example:
<?
set_time_limit( 0);
echo("<html><bo dy>test<br>");
$array1 = array();
$value1 = 1;
for ($index = 0; $index < 160000; $index++)
{
$array1[] = $value1;
}
for($index = 0; $index < 100; $index++)
{
echo("index = $index, value = $array1[$index]<br>");
}
echo("done<br>" );
echo("</body></html>");
exit(0);
?>
If I run the above code it crashes with nothing displayed to the
screen. If I change the loop to go to 80000 instead of 160000 then it
works fine.
Also, I can keep the loop setting at 160000 but change the line:
$array1[] = $value1;
to instead read
$array1[] = 1;
and then it also works fine.
Why does it fail when there are 160000 elements in the array that are
set with a variable?
Thanks,
Mark

Try:
print("index = $index, value = $array1[$index]<br>");flush( );
and see where it goes wrong exactly. it will give you the output directly.

What do you mean by "crashing?" Did Apache (or whatever) blow up or did you
just get a blank page? On computers with small amount of memory, PHP can
indeed crash the server. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I have to read and process a large ASCII file containing a mesh : a
list of points and triangles.
The file is 100 MBytes.
I first tried to do it in memory but I think I am running out of
memory therefore I decide to use the shelve
module to store my points and elements on disks.
Despite the fact it is slow ... Any hint ? I think I have the same
memory problem but I don't understand why
since my aPoint should be removed by the gc.

Normally, if I use

print_r prints nothing and $result is equal to the readable array.
However, if $array is very large, print_r prints the array and returns

Is this correct ? I don't see anything about this in the the manual.
I have tried limiting the size to array to see exactly how large the
