PHP expression "and-statement"? - php

Question

I have this csv file which has 2 rows.
The first one shows the city name and 2nd shows a number (statistic)
Example:
[City] [Count of dogs]
[Los Angeles] [100]
[New York] [-]
Now my problem is that I don't want to show the city's and the statistic from it that have [-] as [Count of dogs].
This is what I've tried right now:
<?php
echo"<table border='1'>";
if (($handle = fopen("table.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 0, ";")) !== FALSE) {
echo "<tr>";
$num = count($data);
for ($i=0; $i < $num; $i++) {
$string = $data[$i];
$m = preg_match("#\w{2,}#", $string, $match);
if ($m) {
echo "<td>". $data[$i];
$m = preg_match("#\d{2}#", $string, $match);
if ($m) {
echo $data[$i] . "<br /> </td>";
}
}
}
echo"</tr>";
}
fclose($handle);
}
echo"</table>";
?>
It doesn't show the "-" right now but it does show the city, I was wondering if a "and-statement" exist for expressions, or is there a different way to do this?
Picture of how it looks right now: [IMG]http://i59.tinypic.com/14sl4xg.jpg[/IMG]

Answer 1

IS it just "-"? Then you can check for it...
while (($data = fgetcsv($handle, 0, ";")) !== FALSE) {
if ($data[1] != "-") {
echo "<tr>";
....
echo "</tr>";
}
}

Answer 2

If, count of dog field is the filtering field, then take that field first before display,
Here I have checked for numeric, because the count of dog is always in numeric, You may use any other logic as you have done using preg_match,
<?php
while (($data = fgetcsv($handle, 0, ";")) !== FALSE) {
if(is_numeric($data[1])) {
//proceed your logic here
}
else {
continue;//to go for the next row
}
?>

Assuming your CSV looks like your example, you can skip the rows where "Number of Dogs" is a dash.
while (($data = fgetcsv($handle, 0, ";")) !== FALSE) {
if( $data[1] == '-' ) {
continue;
}
echo "<tr>";
// ...
}
Or if the dash can also be any other non-number:
while (($data = fgetcsv($handle, 0, ";")) !== FALSE) {
if( !is_numeric($data[1]) ) {
continue;
}
echo "<tr>";
// ...
}
Also, I don't know what the other if checks are for, but it looks to me you want to just echo the data
while (($data = fgetcsv($handle, 0, ";")) !== FALSE) {
if( $data[1] == '-' ) {
continue;
}
echo "<tr>";
$num = count($data);
for ($i=0; $i < $num; $i++) {
echo "<td>" . $data[$i] . "</td>";
}
echo"</tr>";
}

Check the occurrences of - in the second column using strpos function. If the second column doesn't contain any -, then print the row
while (($data = fgetcsv($handle, 0, ";")) !== FALSE) {
$num = count($data);
if (strpos($data[$num-1],'-') === false) {
echo "<tr>";
for ($i=0; $i < $num; $i++) {
$string = $data[$i];
$m = preg_match("#\w{2,}#", $string, $match);
if ($m) {
echo "<td>". $data[$i];
$m = preg_match("#\d{2}#", $string, $match);
if ($m) {
echo $data[$i] . "<br /> </td>";
}
}
}
echo"</tr>";
}
}
