Check Last Digit of String

[Anon]

I know I know, I should be using MySQL... I can't, CIS won't allow it. That aside:

I am taking a CSV file and sticking it in an array with the fopencsv. I have 5 'columns' in this csv file. In my loop that prints the data, how to I make it insert a line break after line 5?

I assume I have to check the incrementing value value to see if the last digit = 4 or 9 but how do I do that? This I copied from the man...

while ($data = fgetcsv ($fp, 1000, ",")) {
$num = count ($data);
$row++;
for ($c=0; $c<$num; $c++) {
print $data[$c];
}
}

I think I need to change it to something like:

while ($data = fgetcsv ($fp, 1000, ",")) {
$num = count ($data);
$row++;
for ($c=0; $c<$num; $c++) {
if (enddigit=(4;9) {
print $data[$c] . "<br>";
}else{
print $data[$c];
}
}
}

But I have no idea how to check that last digit.

Thnx for help.

$variable[strlen($variable)-1]
will return the last digit of a string.

So, if (enddigit=(4;9) should read
if($variable[strlen($variable)-1]=='4' || $variable[strlen($variable)-1] =='9')

I'm going to assume that you mean "insert a break after COLUMN 5" and not "ROW 5"...

You don't need to check the last digit, just use the modulus operator (%). It returns the remainder from a division. Change your if statement to this:

if($c+1 % 5 == 0)

This will put a break after the 5th, 10th, 15th, etc. column.

$row = 1;
$fp = fopen ("$csvfile.csv","r");
while ($data = fgetcsv ($fp, 1000, ",")) {
$num = count ($data);
$row++;
for ($c=0; $c<$num; $c++) {
if ($c[strlen($c)-1]=='4' || $c[strlen($c)-1] =='9') {
print $data[$c] . "<br>";
} else {
print $data[$c];
}
}
}
fclose ($fp);

So now I have this, it doesn't break anywhere. What am I doing wrong?

You are right, I meant column.

That won't break after the 5th column either.

I figured it out, order of operations.

Works now,thnx,
