Hi All,
I recently start working on caching using ob_start(). I have some problem
while caching a file. Please go through the below code
<?php
$cache_file_name = 'testcachefile.txt';
if(!file_exists($cache_file_name))
{
ob_start();
?>
<html>
<title>Cache Test</title>
<head>
<script language="javascript">
function callWithPageLoad()
{
alert('function called');
var str = '';
for(var i=0;i<500;i++)
{ str += i;}
document.getElementById('textDiv').innerHTML = str;
}
</script>
</head>
<body>
<div align="center" id="textDiv"></div>
</body>
<script language="javascript">
callWithPageLoad();
</script>
<?php
$fp = @fopen($cache_file_name, 'w');
// save the contents of output buffer to the file
@fwrite($fp, ob_get_contents());
@fclose($fp);
ob_end_flush();
}
else
{
echo 'from cache<br>';
$handle = fopen($cache_file_name, "rb");
$str = fread($handle, filesize($cache_file_name));
fclose($handle);
echo $str;
}
?>
When i execute this code, caching file is creating as follows
<html>
<title>Cache Test</title>
<head>
<script language="javascript">
function callWithPageLoad()
{
alert('function called');
var str = '';
for(var i=0;i<500;i++)
{ str += i;}
document.getElementById('textDiv').innerHTML = str;
}
</script>
</head>
<body>
<div align="center" id="textDiv"></div>
</body>
<script language="javascript">
callWithPageLoad();
</script>
When i using the cached file, the javascript function is calling again. But
as per my requirement i have to cached the final output and when i runt he
cached file, the JS function would not run again, means i want to cache the
pure html code. for example
<html><head><title>Cache Test</title></head><body>
<div align="center"
id="textDiv">0123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119120121122123124125126127128129130131132133134135136137138139140141142143144145146147148149150151152153154155156157158159160161162163164165166167168169170171172173174175176177178179180181182183184185186187188189190191192193194195196197198199200201202203204205206207208209210211212213214215216217218219220221222223224225226227228229230231232233234235236237238239240241242243244245246247248249250251252253254255256257258259260261262263264265266267268269270271272273274275276277278279280281282283284285286287288289290291292293294295296297298299300301302303304305306307308309310311312313314315316317318319320321322323324325326327328329330331332333334335336337338339340341342343344345346347348349350351352353354355356357358359360361362363364365366367368369370371372373374375376377378379380381382383384385386387388389390391392393394395396397398399400401402403404405406407408409410411412413414415416417418419420421422423424425426427428429430431432433434435436437438439440441442443444445446447448449450451452453454455456457458459460461462463464465466467468469470471472473474475476477478479480481482483484485486487488489490491492493494495496497498499</div>
