I have this string 45.142.34.3920:8945:userq:passwdwhat I want is I need to separate the proxy address and the port and it's username and pasword. So it should look like 45.142.34.3920:8945 and userq:passwd
Would that help to get you started?
$string = '45.142.34.3920:8945:userq:passwd';
$parts = explode(':', $string);
$host = $parts[0] . ':' . $parts[1];
$user = $parts[2] . ':' . $parts[3];
echo $host . PHP_EOL;
echo $user . PHP_EOL;

So i'm creating a simple function to mask phone numbers. My phone numbers have a 9 digits and i want preg_replace them with a given mask like 2-2-2-1-2 or 3-2-2-2 and etc.
I tried this:
$mask = explode('-', '3-2-2-2');
$pattern = '';
$replace = '';
foreach ($mask as $key => $value) {
if ($key == 0) {
$pattern = '/\(?(\d{' . $value . '})\)?[- ]';
$replace = '$' . ++$key . '-';
continue;
}
if ($key == count($mask) - 1) {
$pattern .= '?(\d{' . $value . '})/';
$replace .= '$' . ++$key;
break;
}
$pattern .= '?(\d{' . $value . '})[- ]';
$replace .= '$' . ++$key . '-';
}
return preg_replace($pattern, $replace, '902000810');
and the result is 902-00-08-10. Sometimes getting error preg_replace(): No ending delimiter '/' found. How can i refactor this to not getting errors?
Assuming:
$num = '902000810';
$mask = explode('-', '3-2-2-2');
There're other ways than using regex to format a phone number from the mask.
using formatted strings:
$maskPH = array_map(fn($i) => "%{$i}s", $mask);
$formatI = implode('', $maskPH);
$formatO = implode('-', $maskPH);
$result = vsprintf($formatO, sscanf($num, $formatI));
using unpack:
$format = array_reduce($mask, function ($c, $i) {
static $j = 0;
return "{$c}A{$i}_" . $j++ . "/";
});
$result = implode('-', unpack($format, $num));
preg_replace(): No ending delimiter '/' found
means that your pattern does not terminate with a / as last character.
But all three patterns lack proper formatting:
You should modify them accordingly.
From:
$pattern = '/\(?(\d{' . $value . '})\)?[- ]';
$pattern .= '?(\d{' . $value . '})/';
$pattern .= '?(\d{' . $value . '})[- ]';
To:
$pattern = '/\(?(\d{' . $value . '})\)?[- ]/';
$pattern .= '/?(\d{' . $value . '})/';
$pattern .= '/?(\d{' . $value . '})[- ]/';
I am working on aws signature version 4. Now my concern is that I receive signature from api request at Amazon api gateway and gateway auhorize and authenticate the request and forward to php microservice. Now I want to detect user from signature that is in request headers. How I can resolve this issue.
Below is my working code through I generate aws signature

I am trying to display numbers retrieved from the database, in a specific format in a text box.
There are two ways in which the numbers can be displayed.
When the total numbers are 10
in database (4608061019) Expected output 46-0806-1019
When the total numbers are 13
in database (4608061019100) Expected output 46-0806-1019-100
My progress so far:
While saving the value into the database I am using
preg_replace("/[^0-9]/","",$string); // to make sure all hardcoded "-" are removed while storing.
One possible (regex-using) approach:
$str = '4608061019';
$formatted = preg_replace(
'/(^\d{2}|\d{4})(?!$)/', '$1-', $str);
// 46-0806-1019
Demo. This function doesn't check the string's length - it just adds a hyphen after each relevant sequence of symbols (2 right after the beginning, 4 afterwards).
Easy! If you are sure that there are only these two options, then you can do this way:
Convert the number to an array of numbers:
$number = str_split($number);
Check the length:
if (count($number) == 10)
$number = $number[0] . $number[1] . "-" . $number[2] . $number[3] . $number[4] . $number[5] . "-" . $number[6] . $number[7] . $number[8] . $number[9];
else if (count($number) == 13)
$number = $number[0] . $number[1] . "-" . $number[2] . $number[3] . $number[4] . $number[5] . "-" . $number[6] . $number[7] . $number[8] . $number[9] . "-" . $number[10] . $number[11] . $number[12];
Return the number:
return $number;
The full function here:
function tokenize($number)
{
$number = str_split($number);
if (count($number) == 10)
$number = $number[0] . $number[1] . "-" . $number[2] . $number[3] . $number[4] . $number[5] . "-" . $number[6] . $number[7] . $number[8] . $number[9];
else if (count($number) == 13)
$number = $number[0] . $number[1] . "-" . $number[2] . $number[3] . $number[4] . $number[5] . "-" . $number[6] . $number[7] . $number[8] . $number[9] . "-" . $number[10] . $number[11] . $number[12];
return $number;
}
Output
echo tokenize(4608061019);
echo tokenize(4608061019100);
Output
46-0806-1019
46-0806-1019-100
Fiddle: http://codepad.viper-7.com/EVWeFR
Another alternative solution:
$parts = array(2,4,4,3);
$string = "4608061019100";
$i = 0;
$newString = '';
foreach ($parts as $part) {
$newString.=substr($string, $i, $part) ."-";
$i = $i+$part;
}
$newString = rtrim($newString, "-");
Output is:
string '46-0806-1019-100' (length=16)
Works for 46-0806-1019 too.
try it:
//$number = '4608061019';
$number = '4608061019100';
function formatImportantNumber($theNumber){
$formatedNumber = '';
if(strlen($theNumber)==10){
//46-0806-1019
$formatedNumber = substr($theNumber, 0, 2).'-'.substr($theNumber, 2, 4).'-'.substr($theNumber, 6, 4);
}elseif(strlen($theNumber)==13){
//46-0806-1019-100
$formatedNumber = substr($theNumber, 0, 2).'-'.substr($theNumber, 2, 4).'-'.substr($theNumber, 6, 4).'-'.substr($theNumber, 10, 3);
}else{
die('Invalid number formated')
}
return $formatedNumber;
}
echo formatImportantNumber($number);
i trying to create SAS link to blob resource using PHP. Unfortunately currently in azure SDK there is no method for creating SAS signature.
I wrote a code for generating SAS but when i'm trying to get a resource by the link generated by this method i'm getting this message: Signature fields not well formed.
public function getSharedAccessSignatureURL($container, $blob)
{
$signedStart = date('c', strtotime('-1 day'));
$signedExpiry = date('c', strtotime('+1 day'));
$signedResource = 'b';
$signedPermission = 'r';
$signedIdentifier = '';
$responseContent = "file; attachment";
$responseType = "binary";
$canonicalizedResource = '/'.$this->account['accountName'].'/'.$container.'/'.$blob;

Any suggest what i am doing wrong? I am commpletle newbie at Microsoft Azure
I believe there's an issue with your $stringToSign variable. Based on the documentation here: http://msdn.microsoft.com/en-US/library/azure/dn140255.aspx, your string to sign should be constructed like the following:
StringToSign = signedpermissions + "\n"
signedstart + "\n"
signedexpiry + "\n"
canonicalizedresource + "\n"
signedidentifier + "\n"
signedversion + "\n"
rscc + "\n"
rscd + "\n"
rsce + "\n"
rscl + "\n"
rsct
considering you're including rscd and rsct in your SAS querystring. Please try the following and see if that makes the difference:
$stringToSign =
$signedPermission."\n".
$signedStart."\n".
$signedExpiry."\n".
$canonicalizedResource."\n".
$signedIdentifier."\n".
$signedVersion."\n".
"\n".
$responseContent."\n".
"\n".
"\n".
$responseType;
UPDATE
Please try the code below. Replace the account name/key, container name and blob name with appropriate values:
<?php
$signedStart = gmdate('Y-m-d\TH:i:s\Z', strtotime('-1 day'));
echo $signedStart."\n";
$signedExpiry = gmdate('Y-m-d\TH:i:s\Z', strtotime('+1 day'));
echo $signedExpiry."\n";
$signedResource = 'b';
$signedPermission = 'r';
$signedIdentifier = '';
$accountName = "[account name]";
$accountKey = "[account key]";
$container = "[container name]";
$blob = "[blob name]";
$canonicalizedResource = '/'.$accountName.'/'.$container.'/'.$blob;
$signedVersion = '2014-02-14';
echo $canonicalizedResource."\n";
$rscc = '';
$rscd = 'file; attachment';//Content disposition
$rsce = '';
$rscl = '';
$rsct = 'binary';//Content type
$stringToSign =
$signedPermission."\n".
$signedStart."\n".
$signedExpiry."\n".
$canonicalizedResource."\n".
$signedIdentifier."\n".
$signedVersion."\n".
$rscc."\n".
$rscd."\n".
$rsce."\n".
$rscl."\n".
$rsct;
echo $stringToSign."\n";
$signature = base64_encode(
hash_hmac(
'sha256',
$stringToSign,
base64_decode($accountKey),
true
)
);
echo $signature."\n";
$arrayToUrl = [
'sv='.urlencode($signedVersion),
'st='.urlencode($signedStart),
'se='.urlencode($signedExpiry),
'sr='.urlencode($signedResource),
'sp='.urlencode($signedPermission),
'rscd='.urlencode($rscd),
'rsct='.urlencode($rsct),
'sig='.urlencode($signature)
];
$url = 'https://'.$accountName.'.blob.core.windows.net'.'/'
.$container.'/'
.$blob.'?'.implode('&', $arrayToUrl);
echo $url."\n";
?>
Essentially there were two issues (apart from incorrect $stringToSign variable):
Start/End date time were not properly formatted.
We would need to base64_decode the account key for calculating signature.
I run into exactly the same problem. But now you can use MicrosoftAzure\Storage\Common\SharedAccessSignatureHelper which can handle a lot of problems for you. I has been added to the common libary 2 years ago in this PR (https://github.com/Azure/azure-storage-php/pull/73/files).
And it should be solved very simple like this:
$sasHelper = new SharedAccessSignatureHelper(
'nameofyouraccount',
'H...your-token...=='
);
$sas = $sasHelper->generateAccountSharedAccessSignatureToken(
'2018-11-09',
'rwl',
'b',
'sco',
(new \DateTime())->modify('+10 minute'),
(new \DateTime())->modify('-5 minute'),
'',
'https'
);
$connectionString = "BlobEndpoint=https://nameofyouraccount.blob.core.windows.net/;SharedAccessSignature={$sas}";
And you got your connection string!

I have error in line 2 and 13 in PHP 5.2, I have no idea to make the correction, I tried using create_function but not working, can anyone help with this?
function _process_special_keyword($str){
$callback = function($match){

}
$ret .= $match[4];
return $ret;
};

Thanks.
Error: Parse error: syntax error, unexpected T_FUNCTION
When using create_function(), the contents of the first argument should be a string representation of the PHP code that would fill the parentheses for the function declaration. The second argument should contain only the code inside the curly braces {} of the function declaration, the actual declaration itself should be omitted.
Try this code:
function _process_special_keyword($str){
$callback = create_function(
'$match',
'
$ret = $match[1] . "[" . $match[2] . "]";
if(!empty($match[3])){
$ret .= ".[" . $match[3] . "]";
}
$ret .= $match[4];
return $ret;
'
);
$strSQL = preg_replace_callback('/([\s\(\.,])(' . SPECIAL_KEYWORDS . ')(?:\.(' . SPECIAL_KEYWORDS . '))?([\s\)\.,])/i', $callback, $str);
$callback = create_function(
'$match',
'return "CASE WHEN " . $match[1] . " THEN " . $match[2] . " ELSE " . $match[3] . " END";'
);
$strSQL = preg_replace_callback('/if\s*\((.+),(.+),(.+)\)/i', $callback, $strSQL);
return $strSQL;
}
You can declare the callbacks outside of this function. Like this:
function _callback_one($match){
$ret = $match[1] . '[' . $match[2] . ']';
if(!empty($match[3])){
$ret .= '.[' . $match[3] . ']';
}
$ret .= $match[4];
return $ret;
}
function _callback_two($match){
return 'CASE WHEN ' . $match[1] . ' THEN ' . $match[2] . ' ELSE ' . $match[3] . ' END';
}
function _process_special_keyword($str){
$strSQL = preg_replace_callback('/([\s\(\.,])(' . SPECIAL_KEYWORDS . ')(?:\.(' . SPECIAL_KEYWORDS . '))?([\s\)\.,])/i', '_callback_one', $str);
$strSQL = preg_replace_callback('/if\s*\((.+),(.+),(.+)\)/i', '_callback_two', $strSQL);
return $strSQL;
}
Note: If these functions are in a class (meaning the function would be need to called like $this->_callback_one), pass an array as the "callback" parameter.
function _process_special_keyword($str){
$strSQL = preg_replace_callback('/([\s\(\.,])(' . SPECIAL_KEYWORDS . ')(?:\.(' . SPECIAL_KEYWORDS . '))?([\s\)\.,])/i', array($this, '_callback_one'), $str);
$strSQL = preg_replace_callback('/if\s*\((.+),(.+),(.+)\)/i', array($this, '_callback_two'), $strSQL);
return $strSQL;
}
according with object question, the faster way I think is something like so,
$f = <<<myfunc
\$ret = \$match[1] . '[' . \$match[2] . ']';
if(!empty(\$match[3])){
\$ret .= '.[' . \$match[3] . ']';
}
\$ret .= \$match[4];
return \$ret;
myfunc;
$callback = create_function('$match',$f);
note backslashes before $ and <<< FLAG FLAG; construct. In practice the answer of Rocket is more simple.
