Reading file.

sunitad

I am trying to read a file and extract some strings from it.

I am usinf this code.
It echo's File Opened ok but does not echo $acontent.

Can someone please help me? It's urgent.

Thanks in advance.

if(!$fp = fopen("$filename", "r")){
echo ("Could Not open File");
}
else {
echo("File Opened ok");
$acontent = fread($fp, 20);

echo ($acontent);
fclose($fp);
flush();
}

Since you are only echoing the first 20 chars of the first line of the file, are you sure the first 20 chars of the first line in the file are not blank?

I tried using
$acontent = fread($fp, $MAX_FILESIZE); as well as
$acontent = fread($fp, filesize($test));

None of these worked either.

Which isn't surprising because $MAX_FILESIZE and $test are both undefined in teh script as shown...

I saved strlen into $MAX_FILESIZE which was getting value and
The $test was file name saved before this piece of code.
If you please know How to read complete file Instead of reading a hardcoded #. Please let me now.

Thanks.

My code is now working. It reads a file and echo part of the file which is maked for display purpose. My files are not bigger than 15000 chracters.
It is like this, If anyone needs it in future.

$root defined earliar.

$filename=$root . $content;

$acontent="";
if(!$fp = fopen("$filename", "r")){
echo ("Could Not open File");
}
else {
echo("file open");
}
$acontent = fread($fp,15000);

// echo ($acontent);
fclose($fp);
flush();

if (strstr($acontent,'')) {
echo "" ;
} else {
echo "Substring not found." ;
}

$place1=strpos($acontent, "");

$place2=strpos($acontent, "");

$art=substr($acontent, $place1, $place2-$place1);
echo ($art);

Do you want to just echo the entire contents of the file each time, or do you want to display it line by line?

If you just need to display the entire file then do the following:

$filename=$root . $content;
include $filename;

To read it one line at a time, do the following:

$fd = fopen($filename, "r");
while (!feof ($fd)) {
$acontent = fgets($fd, 4096);
echo $acontent ;
}
fclose ($fd);
