Working, haha, let’s not talk about it, it’s a place I’m not proud of

The fgetss() function provided by the php4.

Regarding the BUG of fgetss, you can use the following code to study it:
$fp=fopen("index.html","r");
while (! feof($fp))
{
$ms=fgetss($fp);
printf($ms);
}
fclose($fp);

Version: Free
* /
function mygets($myFile)
{
//while(!feof($myFile))
//{
$myline = fgets($myFile, 255);

$big=strlen(strstr($myline,">"));
$small=strlen(strstr($myline,"if($big>$small) //This sentence is very important. It is useful if there is a line break in the middle of the HTML code{ //It is useful if > appears first in a line instead of $myline=strstr($myline,">"); $myline=substr($myline,1);
}

$len=strlen($myline);
$startskip=false;
$outstring=""; //important!

for($i=1;$i{ $a=substr($myline,$i -1,1);
switch($a)
{
case "$startskip=true;

//$myline=substr($myline, ">");
//$myline=strstr($myline,1);
break;
case ">":
//$myline=substr($myline,1);
$startskip=false;
break;
default:
}
if(!$startskip && $a!=">") $outstring=$outstring.$a;
}
$outstring=str_replace(" "," ",$outstring);
//Of course, if you don’t want the stuff starting with &, you can add it, just like the same method, here is just filtering
$outstring =str_replace(" ","",$outstring);
$outstring=str_replace("　","",$outstring); //Double quotes are full-width spaces
$outstring=str_replace(" ","",$outstring);
return $outstring;
//}
} ?>
