Extract numbers from phone number input field (PHP) - php

I've got a phone number input field, which allows a user to add a phone number in whatever format they want (555-555-5555, (555) 555 - 5555, etc).
Since it a phone number field only, I can ignore everything but the numbers in the field.
I'm currently using the following code. It extracts all the numbers, but the issue is that they are not in order - it's in a jumbled order.
How do I extract the numbers in the order that they appear in the original string?
preg_match_all('/\d+/', $Phone, $matches);
$Phone = implode('', $matches[0]);
Edit: They are actually not in a jumbled order from this function - I was inserting the numbers into a int(10) database field, which caused the jumbling. But, the answers below are still a more efficient way of accomplishing my goal.

Use preg_replace to remove any non-digits:
$numbers = preg_replace('/[^\d]/','',$Phone);
Note: '[^\d]' can be replaced with '\D' (safe in non-unicode mode).

$Phone = preg_replace('/[^\d]/', '', $Phone);

Why not just replace everything in the string that is not a digit?
$number = preg_replace("/[^0-9]/", '', $Phone);

Try it
if (!preg_match("/^[0-9\-]*$/",$Phone)) {
echo "Only Numeric and strip (-)";
}
Example:
Good: 0877-9320-9356
Failed: 0877 9320 9356 or 087793209356

Format billing phone number on WooCommerce account to add space between code and number

I want to force the phone number on the woocommerce registration field to be like 01234 567890 instead of 01234567890 so it adds a space after the 5th number.
I need the same for the mobile number too.
I've tried a few variations of answers that I found before and added to my functions.php file but it either didn't work or bust my site.
If you receive numbers in different formats you could start replacing all non-digits and then add a space after 5 digits. Here is an example of a function:
function formatPhoneNumber($phoneNumber){
$phoneNumber = preg_replace('/[^0-9]/', '', $phoneNumber); //Replacing non-digits.
$phoneNumber = substr_replace($phoneNumber, ' ', 5, 0); //Adding space after 5 digits.
return $phoneNumber;
}
Try the code here.
If you want to format input fields you can do it with help of JavaScript, in this case with jQuery which is bundled with WordPress.
$("#formInput").keyup(function(){
input = $("#formInput").val();
input = input.replace(/\D/g, ''); //Replacing non digits
if(input.length > 5){ //Adding space if string is larger than 5.
input = [input.slice(0, 5), " ", input.slice(5)].join('');
}
$("#formInput").val(input);
})

PHP - Re-format number with commas

there are several topics with pretty similar questions, but in my specific case, I failed to find an answer.
I have a number, such as:
4,063,500.00
I need it reformatted in
4063500
Is there any inbuilt functionality in PHP or Laravel that allows doing it? Thanks in advance.
Your original number is treated as a string because of the commas. So at minimum you need to remove them before calling intval() which will truncate off the decimal:
<?php
$num = '4,063,500.00';
echo intval(str_replace(',', '', $num));
And the output is:
4063500
You can use regular expression to remove all extra characters except number.
ex removing extra characters from below example.
$num = '4,063,500.00';
$filtered_num = preg_replace("/[^0-9]/", "", substr($num, 0, strpos($num, ".")));
echo $filtered_num;
o/p : 4063500

Weird whitespace error in PHP

I have phone numbers that I want to format
And I have a pattern matcher that breaks down the numbers into a 10 digit format, and then applies dashes.
It works most of the time. However Im having an issue with certain numbers.
$trimmed = trim(preg_replace('/\s+/', '', $v->cust_num));
$tendigit = str_replace(array( '(', ')','-',' ' ), '', $trimmed);
$num = substr($tendigit,0,3)."-".substr($tendigit,3,3)."-".substr($tendigit,6,4);
This will change (555)555 5555, or 555-555 5555 or 5555555555 or (555)-555-5555 or 555-555-5555
to my format of 555-555-5555
However, I came across a few entries in my database, that dont seem to want to change.
One of the bad entries is this one. It contains two white spaces infront of the 4.
4-035-0100
When it runs through $trimmed, and I output $tendigit...it outputs
40350100
as expected. But then when I apply $num to it. It goes back to
4-035-0100
I would at least expect it to be
403-501-00
It seems there is some hidden whitespace in it, that my preg_replace, trim, and str_replace are not attacking.
Any ideas??
Thanks
The code below works, I have tried it with the special characters we discovered in the comments. Basically, the regex removes everything that isnt a number (0-9) and then uses your original formatting.
$trimmed = preg_replace('/\D+/', '', $v->cust_num);
$num = substr($trimmed,0,3)."-".substr($trimmed,3,3)."-".substr($trimmed,6,4);
You can condense your code a little:
$tendigit = preg_replace('/[^\d]/', '', $v->cust_num);
$num = substr($tendigit,0,3)."-".substr($tendigit,3,3)."-".substr($tendigit,6,4);
Though, you should add in some conditions to check that the phone number actually has 10 digits too:
$tendigit = preg_replace('/[^\d]/', '', $v->cust_num);
if(strlen($tendigit == 10)){
$num = substr($tendigit,0,3)."-".substr($tendigit,3,3)."-".substr($tendigit,6,4);
} else {
// catch your error here, eg 'please enter 10 digits'
}
The first line removes any 'non-digit' [^\d].
The conditional statement checks if the $tendigit variable has 10 digits in it.
If it does, then it uses your code to parse and format.
If it doesnt, then you can catch an error.

Big numbers regex

$value = preg_replace("/[^0-9]+/", '', $value);
How could I edit this regex to get rid of everything after the decimal point? There may or may not be a decimal point.
Currently "100.1" becomes 1001 but it should be 100.
Complete function:
function intfix($value)
{
$value = preg_replace("/[^0-9]+/", '', $value);
$value = trim($value);
return $value + 0;
}
It is used to format user input for numbers as well as servers output to format numbers for the DB. The functions deals with very large numbers, so I can't use intval or similar. Any extra comments to improve this function are welcome.
You could just change the regex to /[^0-9].*/s.
.* matches zero or more characters, so the first character that is not a digit, and the digits that immediately follow, would be deleted.
You need to have a pattern that starts the search with a decimal place. At the moment you're only deleting the . not the numbers after it... So you could do '/\.[\d]+/'
$text = "1201.21 12 .12 12.21";
$text = preg_replace('/\.[\d]+/', '' ,$text);
The above code would result in $text = "1201 12 12"
Why not $value = round($value, 0);? This can handle large values and is meant to get rid of the following decimals mathematically (I'd rather work with numbers as numbers not as strings). You can pass PHP_ROUND_HALF_DOWN as a third parameter if you want to just get rid of the decimals 10.7 -> 10. Or floor($value); could work too.

Using regex to fix phone numbers in a CSV with PHP

My new phone does not recognize a phone number unless its area code matches the incoming call. Since I live in Idaho where an area code is not needed for in-state calls, many of my contacts were saved without an area code. Since I have thousands of contacts stored in my phone, it would not be practical to manually update them. I decided to write the following PHP script to handle the problem. It seems to work well, except that I'm finding duplicate area codes at the beginning of random contacts.
<?php
//the script can take a while to complete
set_time_limit(200);
function validate_area_code($number) {
//digits are taken one by one out of $number, and insert in to $numString
$numString = "";
for ($i = 0; $i < strlen($number); $i++) {
$curr = substr($number,$i,1);
//only copy from $number to $numString when the character is numeric
if (is_numeric($curr)) {
$numString = $numString . $curr;
}
}
//add area code "208" to the beginning of any phone number of length 7
if (strlen($numString) == 7) {
return "208" . $numString;
//remove country code (none of the contacts are outside the U.S.)
} else if (strlen($numString) == 11) {
return preg_replace("/^1/","",$numString);
} else {
return $numString;
}
}
//matches any phone number in the csv
$pattern = "/((1? ?\(?[2-9]\d\d\)? *)? ?\d\d\d-?\d\d\d\d)/";
$csv = file_get_contents("contacts2.CSV");
preg_match_all($pattern,$csv,$matches);
foreach ($matches[0] as $key1 => $value) {
/*create a pattern that matches the specific phone number by adding slashes before possible special characters*/
$pattern = preg_replace("/\(|\)|\-/","\\\\$0",$value);
//create the replacement phone number
$replacement = validate_area_code($value);
//add delimeters
$pattern = "/" . $pattern . "/";
$csv = preg_replace($pattern,$replacement,$csv);
}
echo $csv;
?>
Is there a better approach to modifying the CSV? Also, is there a way to minimize the number of passes over the CSV? In the script above, preg_replace is called thousands of times on a very large String.
If I understand you correctly, you just need to prepend the area code to any 7-digit phone number anywhere in this file, right? I have no idea what kind of system you're on, but if you have some decent tools, here are a couple options. And of course, the approaches they take can presumably be implemented in PHP; that's just not one of my languages.
So, how about a sed one-liner? Just look for 7-digit phone numbers, bounded by either beginning of line or comma on the left, and comma or end of line on the right.
sed -r 's/(^|,)([0-9]{3}-[0-9]{4})(,|$)/\1208-\2\3/g' contacts.csv
Or if you want to only apply it to certain fields, perl (or awk) would be easier. Suppose it's the second field:
perl -F, -ane '$"=","; $F[1]=~s/^[0-9]{3}-[0-9]{4}$/208-$&/; print "#F";' contacts.csv
The -F, indicates the field separator, the $" is the output field separator (yes, it gets assigned once per loop, oh well), the arrays are zero-indexed so second field is $F[1], there's a run-of-the-mill substitution, and you print the results.
Ah programs... sometimes a 10-min hack is better.
If it were me... I'd import the CSV into Excel, sort it by something - maybe the length of the phone number or something. Make a new col for the fixed phone number. When you have a group of similarly-fouled numbers, make a formula to fix. Same for the next group. Should be pretty quick, no? Then export to .csv again, omitting the bad col.
A little more digging on my own revealed the issues with the regex in my question. The problem is with duplicate contacts in the csv.
Example:
(208) 555-5555, 555-5555
After the first pass becomes:
2085555555, 208555555
and After the second pass becomes
2082085555555, 2082085555555
I worked around this by changing the replacement regex to:
//add escapes for special characters
$pattern = preg_replace("/\(|\)|\-|\./","\\\\$0",$value);
//add delimiters, and optional area code
$pattern = "/(\(?[0-9]{3}\)?)? ?" . $pattern . "/";
