display problem

[Yang Li Ke]

I have this script which checks multiple domains for a link back to my site:

function backlinkCheck($ siteurl, $recip) {
$arrText = @file($siteurl) ;
for ($i=0; $i<count($arrTe xt); $i++) {
$text = $text . $arrText[$i];
}
if (eregi($recip, $text)) {
return true;
} else {
return false;
}
}

The problem is that It displays true or false only after it went through the
whole list.
Id like it to display each site after they are done. Anyone can tell me how
to do this?

Calling return stops the function and gives control back to the calling
function or script and the loop would stop so no you couldn't for
example return on one then carry on itterating through the list.

This should work as long as $recip will always be on one line, which should be
the case if you're just looking for your domain.

function backlinkCheck($ siteurl, $recip) {
$arrText = @file($siteurl) ;
foreach ($arrText as $text) {
if (eregi($recip, $text))
return true;
}
return false;
}

You also might want to look up foreach, join(), and the ".=" operator for the
future. They aren't needed here any more, but could have made your code a bit
more efficient/readable. You might also want to add some error handling (try
entering a bogus url and see what happens).

Re: display problem

ok but in my main page I call this function like this

while($line = mysql_fetch_obj ect(db_list_of_ sites)){
echo backlinkCheck($ line->url, $mysite->url);
}

so the problem is that it doesnt echo the result after each
site. it echo the results only at end when the whole while
is done !

Thanx for you help.

You should probably have a "$" on db_list_of_site s. This should have produced
an error - I'd suggest turning on error_reporting () if you didn't see it. It
can really help to debug.


while($line = mysql_fetch_obj ect($db_list_of _sites)){
echo backlinkCheck($ line->url, $mysite->url);
}

Re: display problem

You need to 'flush' the output to the browser after each iteration,
check out the following example for some ideas. The usleep call is
there so that you have enough of a delay between each 'flush' to see
the example work.


for( $i=0; $i<100; $i++ ) {
echo $i;
flush();
ob_flush();
usleep(50000);
}
