Ereg

[Anon]

I need to make sure all variables $num1,$num2, $num3, $num4, $num5 are numbers between 0-9.

I'm using:

if(ereg("^{([1-9]*)$",VARIABLE))} {
echo "valid";
}

I can get one variable to work but how can I use foreach or anything so it checks all the variables.

I tried:

$array = array($num1,$num2,$num3,$num4,$num5);
foreach($array as $nums){
if(ereg("^{([1-9]*)$",$nums))} {
echo "valid";
}

But it only checked the first variable. ($num1)

Works for me. Are you sure the other variables have valid numbers? Your loop won't display anything unless the variable contains a string of digits or is empty.

Here's an example with an ereg that checks for numbers from 0-9:

<?php
$num1 = "1";
$num2 = 22;
$num3 = "AAA";

$array = array ($num1,$num2,$num3);
print_r($array);

echo "<BR>";

foreach($array as $nums) {

if(ereg("^{[0-9]$",$nums))} {
echo "$nums is valid <BR>";
}
else {
echo "$nums is not <BR>";
}
}
?>
