I have a variable in php witch can have this shape:
$a = 'help&type=client';
$b = 'account#client';
$c = 'info&type=client#new';
I need to create a substract function that will work like this:
echo myFunction($a); //&type=client
echo myFunction($b); //#client
echo myFunction($c); //&type=client#new
I will rate the more simplified answere.
I think that the simplest way would be using strpbrk.
$a = 'help&type=client';
$b = 'account#client';
$c = 'info&type=client#new';
echo strpbrk($a, '&#') . PHP_EOL; //&type=client
echo strpbrk($b, '&#') . PHP_EOL; //#client
echo strpbrk($c, '&#') . PHP_EOL; //&type=client#new
myFunction would be something like this:
function myFunction($string) {
$amp = strpos($string, '&');
if($amp) {
return substr($string,$amp,strlen($string)-$amp);
} else {
$hash= strpos($string, '#');
return substr($string,$hash,strlen($string)-$hash);
}
}
You might have to change if($amp) to if($amp > 0) depending on what the output of strpos is.
What about this.
$re = "/[&#]([a-z=]+)/";
$str = "help&type=client\naccount#client";
preg_match_all($re, $str, $matches);
http://regex101.com/r/cW3yL6/1
You can use regular expressions for this
preg_match('[^help](.*)', $help, $match)
echo $match[0]; //&type=client
and
preg_match('[^account](.*)', $help, $match)
echo $match[0]; //#client
You can see this website: http://regex101.com/r/zR9eD1/1 for more information about these expressions.
Just a quick explanation:
we do NOT match 'help' and we DO match everything else (after 'help')
edit:
If you only have & or # as a delimiter you can use this:
preg_match('([#].+)', $help, $match)
echo $match[0]; //#client
This matches everything starting with a #
Use a simple preg_split:
function myFunction($var) {
return $var . "\n";
}
$a = 'help&type=client';
$b = 'account#client';
$as = preg_split('/(\w+)/', $a, 2);
$bs = preg_split('/(\w+)/', $b, 2);
echo myFunction($as[1]); // &type=client
echo myFunction($bs[1]); // #client

I'm trying to lowercase every character in a string except for the last one that should be in uppercase.
Here is my code:
function caps_caps($var) {
$var = strrev(ucwords(strrev($var)));
echo $var;
}
caps_caps("HeLlo WOrld"); // should returns "hellO worlD"
This is the easy solution of this problem
function caps_caps($var) {
$var = strrev(ucwords(strrev(strtolower($var))));
echo $var;
}
caps_caps("HeLlo WOrld");
Demo
You also need to convert the string to lowercase first.
function caps_caps($var) {
$var = strrev(ucwords(strrev(strtolower($var))));
echo $var;
}
caps_caps("HeLlo WOrld"); // returns "hellO worlD"
function caps_caps($text) {
$value_to_print = '';
$text = strrev(ucwords(strrev($text)));
$words = explode(' ', $text);
foreach($words as $word){
$word = strtolower($word);
$word[strlen($word)-1] = strtoupper($word[strlen($word)-1]);
$value_to_print .= $word . ' ';
}
echo trim($value_to_print);
}
caps_caps("HeLlo WOrld");
You can try this piece of code.
function uclast($s)
{
$lastCharacterUppar = '';
if ( preg_match('/\s/',$s) ){//If string has space
$explode = explode(' ',$s);
for($i=0;$i<count($explode);$i++){
$l=strlen($explode[$i])-1;
$explode[$i] = strtolower($explode[$i]);
$explode[$i][$l] = strtoupper($explode[$i][$l]);
}
$lastCharacterUppar = implode(' ', $explode);
} else { //if string without space
$l=strlen($s)-1;
$s = strtolower($s);
$s[$l] = strtoupper($s[$l]);
$lastCharacterUppar = $s;
}
return $lastCharacterUppar;
}
$str = 'hey you yo';
echo uclast($str);
Try this, you forgot to do foreach, each elements.
function uclast_words($text, $delimiter = " "){
foreach(explode($delimiter, $text) as $value){
$temp[] = strrev(ucfirst(strrev(strtolower($value))));
}
return implode($delimiter, $temp);
}
print_r(uclast_words("hello world", " "));
I hope this is the answer of your question.
Here is a multibyte safe technique that performs the title-casing with one call instead of two. The string reversal and re-reversal is still necessary.
Code: (Demo)
echo strrev(
mb_convert_case(
strrev('HeLlo WOrld'),
MB_CASE_TITLE
)
);
// hellO worlD
need to extract an info from a string which strats at 'type-' and ends at '-id'
IDlocationTagID-type-area-id-492
here is the string, so I need to extract values : area and 492 from the string :
After 'type-' and before '-id' and after 'id-'
You can use the preg_match:
For example:
preg_match("/type-(.\w+)-id-(.\d+)/", $input_line, $output_array);
To check, you may need the service:
http://www.phpliveregex.com/
P.S. If the function preg_match will be too heavy, there is an alternative solution:
$str = 'IDlocationTagID-type-area-id-492';
$itr = new ArrayIterator(explode('-', $str));
foreach($itr as $key => $value) {
if($value === 'type') {
$itr->next();
var_dump($itr->current());
}
if($value === 'id') {
$itr->next();
var_dump($itr->current());
}
}
This is what you want using two explode.
$str = 'IDlocationTagID-type-area-id-492';
echo explode("-id", explode("type-", $str)[1])[0]; //area
echo trim(explode("-id", explode("type-", $str)[1])[1], '-'); //492
Little Simple ways.
echo explode("type-", explode("-id-", $str)[0])[1]; // area
echo explode("-id-", $str)[1]; // 492
Using Regular Expression:
preg_match("/type-(.*)-id-(.*)/", $str, $output_array);
print_r($output_array);
echo $area = $output_array[1]; // area
echo $fnt = $output_array[2]; // 492
You can use explode to get the values:
$a = "IDlocationTagID-type-area-id-492";
$data = explode("-",$a);
echo "Area ".$data[2]." Id ".$data[4];
$matches = null;
$returnValue = preg_match('/type-(.*?)-id/', $yourString, $matches);
echo($matches[1]);
I have the below string in PHP.
:guest!lbjpewueqi#AF8A326D.E0B4A40D.F85DC93A.IP
I need to create these variables from the string:
$nick = guest
$user = lbjpewueqi
$host = AF8A326D.E0B4A40D.F85DC93A.IP
What is the best function to use to do this?
Ideally I would like to create some sort of function so I can pass to it the string and what part I want returned.
For example:
$string = "guest!lbjpewueqi#AF8A326D.E0B4A40D.F85DC93A.IP";
echo stringToPart($string, nick);
guest
echo stringToPart($string, nick);
lbjpewueqi
echo stringToPart($string, host);
AF8A326D.E0B4A40D.F85DC93A.IP
Another version:
function stringToPart($string, $part) {
if (preg_match('/^:(.*)!(.*)#(.*)/', $string, $matches)) {
$nick = $matches[1];
$user = $matches[2];
$host = $matches[3];
return isset($$part) ? $$part : null;
}
}
More strict than preg_split solutions - it checks separators order.
Maybe this code may helpful for you
$p = '/[:!#]/';
$s = ":guest!lbjpewueqi#AF8A326D.E0B4A40D.F85DC93A.IP";
print_r( preg_split( $p, $s ), 1 );
You can declare a function like this:
$s = ":guest!lbjpewueqi#AF8A326D.E0B4A40D.F85DC93A.IP";
function stringToPart($str, $part) {
$pat['nick'] = '/:(.*)!/';
$pat['user'] = '/.*!(.*)#/';
$pat['host'] = '/#(.*)/';
preg_match($pat[$part], $str, $m);
if (count($m) > 1) return $m[1];
return null;
}
echo stringToPart($s,'nick')."\n";
echo stringToPart($s,'user')."\n";
echo stringToPart($s,'host')."\n";
The below should do what you're looking for.
$pattern = "/[:!#]/";
$subject = ":guest!lbjpewueqi#AF8A326D.E0B4A40D.F85DC93A.IP";
print_r(preg_split($pattern, $subject));
The pattern is specifying what characters to split on so you could in theory have any amount of characters here if there were other instance you needed to account for different strings being passed in.
To return the values instead of just printing then to the screen use this:
$pattern = "/[:!#]/";
$subject = ":guest!lbjpewueqi#AF8A326D.E0B4A40D.F85DC93A.IP";
$result = preg_split($pattern, $subject));
$nick = $result[1];
$user = $result[2];
$host = $result[3];
stringToPart(':guest!lbjpewueqi#AF8A326D.E0B4A40D.F85DC93A.IP','nick');
function stringToPart($string, $type){
$result['nick']= substr($string,strpos($string,':')+1,(strpos($string,'!')-strpos($string,':')-1));
$result['user']= substr($string,strpos($string,'!')+1,(strpos($string,'#')-strpos($string,'!')-1));
$result['host']= substr($string,strpos($string,'#')+1);
return $result[$type];
}
<?php
function stringToPart($string, $key)
{
$matches = null;
$returnValue = preg_match('/:(?P<nick>[^!]*)!(?P<user>.*?)#(?P<host>.*)/', $string, $matches);
if (isset($matches[$key]))
{
return $matches[$key];
} else
{
return NULL;
}
}
$string = ':guest!lbjpewueqi#AF8A326D.E0B4A40D.F85DC93A.IP';
echo stringToPart($string, "nick");
echo "<br />";
echo stringToPart($string, "user");
echo "<br />";
echo stringToPart($string, "host");
echo "<br />";

i need to change this line: count(id)
to line like this count(tableName.id)
i try to do this with preg match and replace like this:
$a = "count(id)";
$regex = "/\w{3,}+\W/";
$dd = preg_match("/\(.*?\)/", $a, $matches);
$group = $matches[0];
if (preg_match($regex, $a)) {
$c = preg_replace("$group", "(table.`$group`)", $a);
var_dump($c);
}
output that i got is : count((table.(id))) its outputting me extra brackets . i know the problem but i can't find solution because my regex knowledge not so good.
$a = "count(id)";
$regex = "/\w{3,}+\W/";
$dd = preg_match("/\((.*?)\)/", $a, $matches);
$group = $matches[1]; // <-- you'll get error if the above regex doesn't match!
if (preg_match($regex, $a)) {
$c = preg_replace("/$group/", "table.$group", $a);
}
I am trying to find the word and add a number next to it. How could he do? I tried with the code below, but I could not. Could anyone help me?
Thank you!
$string = 'I220ABCD I220ABCDEF I220ABCDEFG'
if (preg_match("/I220.*/", $string, $matches)) {
echo $matches[0];
}
Expected result:
I220ABCD9
I220ABCDEF10
I220ABCDEFG11
Use preg_replace_callback instead like this:
$str = 'I220AB FRRRR CD I221ABCDEF I220AB DSFDSF CDEFG';
$repl= preg_replace_callback('~(I220[^\s]+)~', function($m) {
static $i=9;
return $m[1] . $i++;
}, $str);
echo $repl\n"; // I220AB9 FRRRR CD I221ABCDEF I220AB10 DSFDSF CDEFG
I dont know what your requirnments for adding the number at the end are so i just incremeneted during the loop;
$string = 'I220ABCD I220ABCDEF I220ABCDEFG';
$arrayStrings = explode(" ", $string);
$int = 9;
$newString = '';
foreach($arrayStrings as $stringItem)
{
if (preg_match("/I220.*/", $stringItem, $matches))
{
$stringItem = $stringItem.$int;
$newString = $newString.$stringItem." ";
$int++;
}
}
echo $newString;
Use preg_replace_callback():
$string = 'I220ABCD I220ABCDEF I220ABCDEFG';
// This requires PHP5.3+ since it's using an anonymous function
$result = preg_replace_callback('/I220[^\s]*/', function($match){
return($match[0].rand(0,10000)); // Add a random number between 0-10000
}, $string);
echo $result; // I220ABCD3863 I220ABCDEF5640 I220ABCDEFG989
Online demo.
You'll need to use a catch block in your regex e.g. "/I220([^ ]+)/" and if you want them all, you'll need to use preg_match_all, too.
preg_replace_callback with your needs:
$string = 'I220ABCD I220ABCDEF I220ABCDEFG';
class MyClass{
private static $i = 9;
private static function callback($matches){
return $matches[0] . self::$i++;
}
public static function replaceString($string){
return preg_replace_callback('/I220[^\s]+/',"self::callback",$string);
}
}
echo(MyClass::replaceString($string));
of course you can edit to class to initialize the way you want
