Output Buffer
bool ob_start ( [callback output_callback [, int chunk_size [, bool erase]]])
This function will turn output buffering on. While output buffering is active no output is sent from the script (other than headers), instead the output is stored in an internal buffer.
The contents of this internal buffer may be copied into a string variable using ob_get_contents(). To output what is stored in the internal buffer, use ob_end_flush(). Alternatively, ob_end_clean() will silently discard the buffer contents.
Example:
<?php
// Buffer the current html page so we can write it to file later
ob_start();
$var = "Generated html script";
?>
<html>
<head>
<title>HTMLGEN</title>
</head>
<body>
Loading.... <br />
<?php echo $var; ?>
More contents!<br />
</body>
</html>
<?php
// Write the buffered HTML file
$fp = fopen($htmlFile, 'w');
fwrite($fp, ob_get_contents());
fclose($fp);
ob_end_flush();
?>
