The thing to look for, is how did you get $inputfile out of the
command line, and why you'd expect the file name to be in $argv[1] at
that point? Marco's suggestion isn't really going to work as
$inputfile will be a file handle, and filesize() needs the name of the
file. Maybe want to give us a wider look at what your code is doing?
Generically, you can wrap this up as:
function binread_file($filename)
{
$handle = fopen($filename,'rb');
if (FALSE === $handle) die("Unable to open $filename");
$contents = fread($handle, filesize($filename));
if (FALSE === $contents) die("Unable to read $filename");
return $contents;
}

I know that I must be missing something really ridiculous, but when I
print_r these arrays they are empty. I have confirmed that $arrayElement
is properly formed, it just seems that array_push is not working. I know
I have done this before, but I cannot find my older code. Can someone
clear the mud from my eyes?
$issueDifferently = array();
$issueProblem = array();
$issueComment = array();
function addToArray($id, $namecred, $product, $level, $type, $message) {
$arrayElement = $id
.'|'.$namecred.'|'.$product.'|'.$level.'|'.$type.'|'.$message;
if('DoDifferently' == $type) {
array_push($issueDifferently, $arrayElement);
} elseif ('Problem' == $type){
array_push($issueProblem, $arrayElement);
} elseif ('Comments' == $type) {
array_push($issueComment, $arrayElement);
}
}
print_r($issueDifferently);
print_r($issueProblem);
print_r($issueComment);

You have to declare the arrays as global inside your function.

Hi all. I want to apply strtolower() AND trim() to all items in an array. But I
don't see a way to call multiple callbacks with the array_map() function.
Are my two choices the following:
// 1) nesting two array_map() calls
$cleanData = array_map('trim',(array_map('strtolower',$rawData)));
// 2) call my own function with array_walk()
$cleanData = array_walk('myCleaner',$rawData);
function myCleaner($passedData){
$cleanData = array_map('strtolower',$passedData);
$cleanData = array_map('trim',$cleanData);
}
//(Of course, wouldn't bother with a function, just to call array_map twice...)
Just seeing if there's a better way than having to go through the array twice
to apply each callback separately. Thanks,

Something like:
$cleanData = array_map(function($str){return strtolower(trim($str));},
$passedData);
