Hi,
I have text with numbers.
I want to read text ,find numbers and get required numbers from string.
For example.
“my description has 123456789 numbers”.
I want to get first four numbers from above message using php.
$string = ‘my description has 123456789 numbers’;
$number = preg_replace(“/[^0-9]/”, ‘’, $string); // return 123456789
I mean I need 1234 from above string.
Any idea?
-Thanks
Yep, put a limit match on it.
$string = 'my description has 123456789 numbers';
$number = preg_replace("/[^0-9]{1,4}/", '', $string); // return 1234
Hi,
I am getting out as 123456789 instead 1234.
$string = 'my description has 123456789 numbers';
$number = preg_replace("/[^0-9]{1,4}/", '', $string); // return 1234
echo"<br>".$string; // my description has 123456789 numbers
echo"<br>".$number; // 123456789
Could please check at your end.
-Thanks
Sigh, sorry, I missed the fact you were using preg_replace instead of preg_match.
$matches = [];
$string = 'my description has 123456789 numbers';
if (preg_match("/[0-9]{4}/", $string, $matches)) // find only numbers and collect the first group of 4 numbers
{
var_dump($matches); // if a match of 4 numbers is found, dump the matches array so you can see you can access it using $matches[0]
}
Hi,
I try your solution and it gives me result but it remove message.
Do you have any idea about how to cut number from message.
I want to cut 123456789 to 1234 and keep rest of message as it is.
<?php
function countDigits($str)
{
$NumberArray = array();
$noDigits=0;
for ($i=0;$i<strlen($message);$i++) {
if (is_numeric($message($i))) {
$noDigits++;
array_push($NumberArray,$message($i));
}
//return $noDigits;
}
echo"<pre>";
print_r($NumberArray);
echo"</pre>";
}
function sanitize_message($message,$email = true, $numbers = true, $url = true )
{
//$message = strip_tags( $message );
if($email)
{
//strip email address
$email_regexp = "[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\\.[A-Za-z0-9-]+)*(\\.[A-Za-z]{2,3})";
$message = ereg_replace($email_regexp, '', $message);
}
if($numbers)
{
/*
if (preg_match("/[0-9]{4}/", $message, $matches)) // find only numbers and collect the first group of 4 numbers
{
var_dump($matches); // if a match of 4 numbers is found, dump the matches array so you can see you can access it using $matches[0]
}
echo"<pre>";
print_r($matches);
echo"</pre>";
echo"<br>".$matches[0];
*/
//echo count($numbers);
//strip all numerical values
$number_regexp = "[0-9]";
$message = ereg_replace($number_regexp,'',$message);
}
//eliminate url from message
if($url)
{
$url_regexp = "(https?://)?(www\\.)?([a-zA-z0-9\\.])*[a-zA-Z0-9]*\\.[a-z]{2,3}";
$message = ereg_replace($url_regexp, '', $message);

So you want to take
$string = 'my description has 123456789 numbers';
And turn it into?
$string = 'my description has 1234 numbers';
And a follow up question, what would you do if you have to sets of numbers in the string?
$string = 'my description has 123456789 numbers and 987654321 in it';
Would you expect
$string = 'my description has 1234 numbers and 9876 in it';
or
$string = 'my description has 1234 numbers and 987654321 in it';
Kind of a “rushed” solution and I’m sure there is a more elegant one, but it looks to get the job done.
<?php
$matches = [];
$string = 'my description has 123456789 numbers';
if (preg_match("|[0-9]+|", $string, $matches))
{
$newString = preg_replace("|" . preg_quote($matches[0]) . "|", substr($matches[0], 0, 4), $string);
var_dump($newString); // 'my description has 1234 numbers'
}
$string = 'my description has 123456789 numbers and 987654321 in it';
if (preg_match("|[0-9]+|", $string, $matches))
{
$newString = preg_replace("|" . preg_quote($matches[0]) . "|", substr($matches[0], 0, 4), $string);
var_dump($newString); // 'my description has 1234 numbers and 987654321 in it'
}
$string = 'my description has 123456789 numbers and 987654321 in it';
if (preg_match_all("|[0-9]+|", $string, $matches))
{
$newString = $string;
foreach ($matches[0] as $match)
$newString = preg_replace("|" . preg_quote($match) . "|", substr($match, 0, 4), $newString);
var_dump($newString); // 'my description has 1234 numbers and 9876 in it'
}
Many Many thanks cpradio .
You are excellent programmer.

Needed a slight tweak to prevent recurrance. (“My description has 12345 numbers and 12345 points!” => “My description has 1234 numbers and 12345 points!”)
