Check That Certain Characters Exist in a File

[likelylad]

Hopefully someone can me with this one.

I have text files that need to be read and checked to see if they contained particular pre-defined characters.

All I can do at the moment is open the text file and output it to a page.

What I would like to do is read the text file one character at a time and compare it against my list of pre-defined characters and then output how many pre-defined characters it found.

Can anyone set me off in the right direction as to what the best functions would be to use

Thanking in advance for any help received.

Your starter for 10....

the amount of data in the text file would say how i would do this, how big is the file?

To err is human, to completely mess up takes a computer.

How about all the file functions --

fgetc()
fscanf()
fgets()
fread()
etc...

More Help Please

At the moment I can
I can read the contents of a file.
I am spliting the file contents at the new line character.
How do I loop through each line.
I know I should be using a do...while but I don't know how to close the loop

This is my code so far


$filename = 'c:\test.txt';
$fp = fopen($filename, "r"
$contents = fread($fp, filesize($filename));
fclose($fp);

$splitfile=preg_split("/[\n]/",$contents);

echo $splitfile[0];

I have found a solution to this one

I am using the count function to count the number of elements in the array so that I know how many time I have to loop
