Array Little Problem!

[npsari]

Hello,

This script is useful. It extracts the numbers.

I am trying to echo the first number only!

 

<?php

function extract_numbers($string) { 
preg_match_all('/([\d]+)/', $string, $match); 
return $match[0]; 
}
$string = '32hello42good32morning'; 

$numbers_array = extract_numbers($string); 
echo '<pre>'; print_r($numbers_array); echo "</pre>";


$get_first_number = $array["$numbers_array"][0]; 
echo "$get_first_number";

?> 

 

$get_first_number is not showing

$get_first_number should be 32

Can you please fix the script for me?

$get_first_number = $numbers_array[0]; 
echo $get_first_number;

 

You haven't created a multi-dimensional array, nor have you created an array called $array - so use the above code rather than your last two lines.

Why not just use:

 

preg_replace('/[^0-9]/', '', $string);

Thank you for the replies...

 

I just want to echo $get_first_number, and when I do, it should give me 32

 

function extract_numbers($string) { 
preg_match_all('/([\d]+)/', $string, $match); 
return $match[0]; 
}
$string = '32hello42good32morning'; 

 

Untill now, I have the above script... What happens after that? Can you complete it so $get_first_number will print 32

I already gave you a working answer.

 

<?php

function extract_numbers($string) { 
preg_match_all('/([\d]+)/', $string, $match); 
return $match[0]; 
}
$string = '32hello42good32morning'; 

$numbers_array = extract_numbers($string); 

echo $numbers_array[0];

?>

Monkeh, I am sorry, I did not see your previous script.

I just saw the words.

Thank you much.

Yes, it works now.

Good job friend.
