I've googled and now I'm turning to the local PHP'ers for help.

I've written a PHP CLI application that runs as a constant background process on our Unix server. The problem I get is, as the application does its job, it slowly builds up memory and never releases it. Eventually it hits the memory_limit I've specified in the ini and fails. I've used the unset() function on my objects once they are not needed and then the app goes to sleep for 30 seconds. However, the memory is never released. I am STUMPED! I could really use some help.

Here is an example of a small script that builds up the memory and then tries to free it up; it doesn't work:

<code>#!/usr/local/bin/php -c /usr/local/etc/php-cli.ini
<?PHP
class TestObj{
private $testArr;

public function __construct(){}
public function __destruct(){}

public function testme(){
$this->testArr = array();

for($i = 0; $i < 100000; $i++){
$something = "";

for($j = 0; $j < 10; $j++){
$something .= chr(rand(35,126) );
}
$this->testArr[$i] = $something;
}
}
}

echo "Initial Memory Usage: ".memory_get_usage()."\n\n";
sleep(10);

echo "Creating New Object\n\n";
$test = new TestObj();
echo "Running Test Function\n\n";
$test->testme();

echo "Ready to destroy object in...";
for($x=5 ; $x > 0; $x--){
sleep(1);
echo $x, "...";
}

unset($test);

echo "\nSleepy Time\n";

//Goto Sleep so we can monitor the memory

sleep(30);
?>
