[RESOLVED] Read and Search text File ! return result as var.

Mad_T

Hi
I have a text file of about 3000 lines.

I need to search this for a specific value that will be 'hidden' within a line.
Once the value is found, I need to capture the entire line to a $var, so I work with the value within that line.

Any pointers ??

This is what I've got (not a lot !)

$file = file_get_contents("test.txt");
if(strpos($file, "MAC_Address")) {     

echo "String found!";                 

} else {
	echo "String not found";     

}

Thanks 🙂

Why not read the file line by line. That way the line can already be stored in a variable then you can do the strpos on that variable.

<?php
$file = fopen("test.txt", "r") or exit("can't open file");
while(!feof($file))
{
$line = fgets($file);
if(strpos($line, "MAC_Address"))
{     

echo "String found!";                 

}
else
{
    echo "String not found";     

} 
}
fclose($file);
?>

Thanks, I'd just come up with this:

$file = file('test.txt');
$success = array();
$num = 1;
$phrase = "mac_address";

foreach ($file as $line) {
if (strpos($line, $phrase)) {
$success[] = $num;
$fullline[] = $line;
}
$num++;
}

echo $fullline[0];

Seems to work !!
Thanks again.
