Ok. Totally at a loss here.

 

Reading a text file from a server.

 

I've exploded a comma delimited line of text into an array.

 

Print_r shows $ExpParts[7] to be a capital 'I'.

 

However, this statement evaluates as false: If $ExpParts[7] == 'I' .

 

strcmp($ExpParts[7], 'I') gives me a value of 2.

 

Any help here would be appreciated. I've looked and googled until there's only a few small tufts of hair left on my head:

 

print_r output: Array ( [0] => $ACD [1] => 01/04/2008 [2] => 4070.19 [3] => 4070.19 [4] => 4006.70 [5] => 4008.95 [6] => 0 [7] => I )

 

Code:

 

  $ExpParts = explode(",", $ExpFilLine);
   print_r ($ExpParts);
   If (($ExpParts[7] == 'D') or ($ExpParts[7] == 'U')) $ValidInp = True; 
   $Eq = strcmp($ExpParts[7], 'I');
    print ('Equal is -' . $Eq);
   If ($ExpParts[7] == 'I') print ('Its an I for crissakes');
   If ($Eq == 0) print ('Its a F.....g I');

hi,

I wrote this code to check

 

$str='$ACD,12/14/2007,4147.43,4147.43,4130.07,4135.01,0,I';

$str_arr=explode(',',$str);

echo '<pre>';

print_r($str_arr);

if(trim($str_arr[7]) == 'I')

{

echo 'printing I';

}

else

{

echo 'whats this';

}

 

now it is printing me I

 

whats the problem???/

The problem is you're not reading a flat .txt file off a server.

 

You're comparing apples to apples...........obviously I'm comparing apples to oranges somehow..........z

 

Even if you are going to read a flat .txt how it matters???

 

you might be doing something

 

$str=file_get_contents('file');

 

this function return the file content in string .

and if not like this then you sud tell us how you are doing and in your code    what this signifyies 'applies==orange'???? or 'apple == apple'

If ($ExpParts[7] == 'I') print ('Its an I for crissakes');

 

get cool and tell me which function you are using for reading file in string?

Try this

 

$file_arr_content=file('dummy.txt'); use file command to read file in array

 

REPLACE THIS DUMMY.TXT WITH YOUR TXT FILE I TOOK SOME LINES FRM YOUR FILE AND PROCESSED IT.

 

---------------- Reading file in array------------

print_r($file_arr_content);

 

------------ Now explode usign ','--------------

$str_arr=explode(',',$file_arr_content[0]);

if(trim($str_arr[7]) == 'I')

{

echo 'printing I';

}

else

{

echo 'whats this';

}

$filename = "stkall" . $CurrUpdDate . ".txt";
print ($filename);
$count = 0; 
$fd = fopen ($filename, "r") or exit("Unable to open file!");
$ExpFilLine = fgets($fd);
$ExpParts = explode(",", $ExpFilLine);
nextDat();

 

It originally had a .sto extension, and I uploaded it using the html form 'file' upload function.

 

I'm thinking it uploaded it as binary instead of ASCII or something..........still playing around with it, but these types of problems really freak me out............there's enough programming type bugs/problems without something this simple throwing a monkey wrench into the works.............z

try above code posted and let us know still you are in same problem?

 

Ok. Thanks for all the help guys!!.......I'll try that and see what happens..........z

 

Hey wait just do this change in your code.

 

  $Eq = strcmp(trim($ExpParts[7]), 'I');

and you would be able to solve this .I think extra spaces are the problem so where ever you are comparing just use trim() function .

 

remember : strcmp:Returns < 0 if str1 is less than str2 ; > 0 if str1 is greater than str2 , and 0 if they are equal.

Because your text file is very big ( Well you should know this before ) .I think you need to give some time to your browser to perform the whole set of action and then check the output.If it fails then script will time out.

Yeah, I should have taken a portion of it........no problem, I've got PHP set for extra time........Thanks again.

 

But why didn't it work, i.e. why do you need to do the Trim function (not sure what that does, but I guess it trims extraneous crap off or something)..........z

well

 

' I' is not equal to 'I'.... because space is considered while you compare.

 

so when you do comparision you have to trim off all exta spaces from left and right side of your string.

Ok, I guess the explode added a space or something...maybe because the I was at the end of the record or something.......

 

Thank you again!!!!!!!!!!!!!!!!!!!!!...................z
