Each stream pointer to php://memory and php://temp has its own memory allocation, so you can open many stream pointers to store your separated values.
<?php
$fp = fopen("php://temp", "r+");
$fp2 = fopen("php://temp", "r+");
fwrite($fp, "line1\n");
fwrite($fp2, "line4\n");
fwrite($fp, "line2\n");
fwrite($fp2, "line5\n");
fwrite($fp, "line3\n");
fwrite($fp2, "line6\n");
var_dump(memory_get_usage());
rewind($fp);
while(!feof($fp)) {
var_dump(fread($fp, 1024));
}
fclose($fp);
var_dump(memory_get_usage());
rewind($fp2);
while(!feof($fp2)) {
var_dump(fread($fp2, 1024));
}
fclose($fp2);
var_dump(memory_get_usage());
?>
Closing their stream handles will also free the allocated memory.
php://memory stream type is MEMORY, while php://temp stream type is STDIO FILE*.
