I want to write my own little translation function.
My JSON File looks like:
{
"start": {
"body": {
"headline": "Hello, world!"
}
}
}
In my PHP Frontend, i want to write just Placeholders for translated Strings. So id do
<h1><?php trans('start.body.headline'); ?></h1>
My PHP Function is simple and looks like:
function trans($string) {
if (!isset($_GET['langID']))
$lang = 'de';
else
$lang = $_GET['langID'];
$str = file_get_contents('lang/'. $lang . '.json');
$json = json_decode($str);
$string = str_replace('.', '->', $string);
echo $json->$string;
}
But I don't get a Result.
The $string in My Function is correctly:
start->body->headline
And when I write:
echo $json->start->body->headline;
I get "Hello, world".
echo $json->$string;
is the same but doesn't work. why?
becouse you are using the some variable name $string for function parameter , use the other variable name here.
$keyword = str_replace('.', '->', $string);
echo $json->{$keyword};
also you can use return method
function trans($string) {
if (!isset($_GET['langID']))
$lang = 'de';
else
$lang = $_GET['langID'];
$str = file_get_contents('lang/'. $lang . '.json');
$json = json_decode($str);
$keyword = str_replace('.', '->', $string);
return $json->{$keyword};
}
and than use short way of echo in html
<h1><?= trans('start.body.headline'); ?></h1>

I am using PHP 7.2.4, I want to make a template engine project,
I try to use preg_replace to change the variable in the string,
the code is here:
<?php
$lang = array(
'hello' => 'Hello {$username}',
'error_info' => 'Error Information : {$message}',
'admin_denied' => '{$current_user} are not Administrator',
);
$username = 'Guest';
$current_user = 'Empty';
$message = 'You are not member !';
$new_string = preg_replace_callback('/\{(\$[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*)\}/', 'test', $string);
function test($matches)
{
return '<?php echo '.$matches[1].'; ?>';
}
echo $new_string;
But it just show me
Hello , how are you?
It automatically remove the variable...
Update:
here is var_dump:
D:\Wamp\www\t.php:5:string 'Hello <?php echo $username; ?>, how are you?' (length=44)
You may use create an associative array with keys (your variables) and values (their values), and then capture the variable part after $ and use it to check in the preg_replace_callback callback function if there is a key named as the found capture. If yes, replace with the corresponding value, else, replace with the match to put it back where it was found.
Here is an example code in PHP:
$values = array('username'=>'AAAAAA', 'lastname'=>'Smith');
$string = 'Hello {$username}, how are you?';
$new_string = preg_replace_callback('/\{\$([a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*)}/', function($m) use ($values) {
return 'Hello <?php echo ' . (!empty($values[$m[1]]) ? $values[$m[1]] : $m[0]) . '; ?>';
}, $string);
var_dump($new_string);
Output:
string(47) "Hello Hello <?php echo AAAAAA; ?>, how are you?"
Note the pattern charnge, I moved the parentheses after $:
\{\$([a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*)}
^ ^
Actually, you may even shorten it to
\{\$([a-zA-Z_\x7f-\xff][\w\x7f-\xff]*)}
^^
Do you want something like this?
<?php
$string = 'Hello {$username}, how are you?';
$username = 'AAAAAA';
$new_string = preg_replace('/\{(\$[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*)\}/', $username, $string);
echo $new_string;
The result is:
Hello AAAAAA, how are you?
The more simple way would be to just write
<?php
$username = 'AAAAAA';
$string = 'Hello '.$username.', how are you?';
I'm a fan of keeping it simple so I would use str_replace since it will also change all instances which may come in handy as you go forward.
$string = 'Hello {$username}, how are you?';
$username = 'AAAAAA';
echo str_replace('{$username}',$username,$string);
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
Here is the situation. I have 2 files
content.php
<?php $my_var = "this is a variable"; ?>
<h1> php{my_var} </h1>
index.php
<?php include "content.php" ?>
The result should be:
<h1>this is a variable</h1>
I know how to work with preg_replace_callback. But I don't know how can I change php{my_var} with the value of $my_var.
All the logic should happens inside the index.php.
Edit
index.php
function replace_pattern($match)
{
what should I write here
}
echo preg_replace_callback("/php\:\{(.*)\}/", "replace_pattern", $Content);
Edit 2
Variables are not declare in the global scope
Note the added question-mark in the regular expression to make it less greedy.
$my_var = 'Hello World!';
// Get all defined variables
$vars = get_defined_vars();
$callback = function($match) use ($vars)
{
$varname = $match[1];
if (isset($vars[$varname])) {
return $vars[$varname]; // or htmlspecialchars($vars[$varname]);
} else {
return $varname . ' (doesn\'t exists)';
}
};
echo preg_replace_callback("/php\:\{(.*?)\}/", $callback, $Content);
Demo: http://phpfiddle.org/main/code/ax15-bpyw
Try this:
$my_var = "this is a variable";
$string = '<h1> php{my_var} </h1>';
$pattern = '/php{(.*)}/i';
preg_match($pattern, $string, $match);
$varName = $match[1];
$newString= preg_replace($pattern, $$varName, $string);
echo $newString;
But, warning!
In this case, i assume, if the code is php{somethin}, then there should be a $something variable. I used dynamic variable name. If you want to use only $my_var then use like this:
$newString= preg_replace($pattern, $my_var, $string);
I have a html doc that has links in it.
Example :
http://mysite1.com/test/whatIwant/Idontwantthis
http://mysite1.com/test/whatIwant2/Istilldontwantthis
http://mysite1.com/test/whatIwant3/Idontwantthiseither
I want to replace these with:
http://myothersite.com/whatIwant
http://myothersite.com/whatIwant2
http://myothersite.com/whatIwant3
How can I do this? I feel like the only way is to use str_ireplace to get the value that I want and append it to the other link, I just can't seem to remove the part after the value that I want.
I use:
$var= str_ireplace("http://mysite1.com/test/", "http://myothersite.com/", $var);
But then I get the after value still on the link:
http://myothersite.com/whatIwant/Idontwantthis
I tried and now am turning to the community for help.
Thanks
Oh and they are enclosed in the tag with class and other attributes, all I need to change is the URL as explained above.
The links are not in an array they are being edited from a javascript file so they will be in a large variable as text.
$examples =
'http://mysite1.com/test/whatIwant/Idontwantthis http://mysite1.com/test/whatIwant2/Istilldontwantthis http://mysite1.com/test/whatIwant2/Istilldontwantthis
http://mysite1.com/test/whatIwant3/Idontwantthiseither'
;
Edit: using your updated example, you can split those URLs up by the whitespace between them:
$examples = 'http://mysite1.com/test/whatIwant/Idontwantthis http://mysite1.com/test/whatIwant2/Istilldontwantthis http://mysite1.com/test/whatIwant2/Istilldontwantthis http://mysite1.com/test/whatIwant3/Idontwantthiseither';
$examples = explode(' ', $examples);
Alternative example array:
$examples = array(
'http://mysite1.com/test/whatIwant/Idontwantthis',
'http://mysite1.com/test/whatIwant2/Istilldontwantthis',
'http://mysite1.com/test/whatIwant3/Idontwantthiseither'
);
Regex solution:
$pattern = '/^(?:http|https):\/\/.+\/.*\/(.+)\/.*$/Um';
$replace = 'http://myothersite.com/$1';
foreach($examples as $example) {
echo preg_replace($pattern, $replace, $example);
}
Non-regex solution:
foreach($examples as $example) {
// remove the original domain name
$first = str_ireplace('http://mysite1.com/test/', '', $example);
// prepend the new domain name with the first part of the remaining URL
// e.g. strip everything after the first slash
echo 'http://myothersite.com/' . explode('/', $first)[0];
}
Note: using explode(...)[0] is array dereferencing, and is supported in PHP >= 5.4.0. For previous versions of PHP, use a variable to store the array before referencing it:
$bits = explode('/', $first);
echo 'http://myothersite.com/' . $bits[0];
From the manual:
As of PHP 5.4 it is possible to array dereference the result of a function or method call directly. Before it was only possible using a temporary variable.
Example output:
http://myothersite.com/whatIwant
http://myothersite.com/whatIwant2
http://myothersite.com/whatIwant3
This function should do the job.
<?php
function EditLink($link)
{
$link = explode("/",$link);
return $link[4];
}
$new_link = "http://myothersite.com/".EditLink("http://mysite1.com/test/whatIwant/Idontwantthis")."";
echo $new_link;
?>
Try this no regex:
$urls = array(
'http://mysite1.com/test/whatIwant3/Idontwantthiseither',
'http://mysite1.com/test/whatIwant/Idontwantthis',
'http://mysite1.com/test/whatIwant2/Istilldontwantthis'
);
$new_site = "http://myothersite.com/";
foreach ($urls as $url) {
$pathinfo = pathinfo($url);
$base = basename($pathinfo['dirname']);
$var = str_ireplace($url, $new_site . $base, $url);
echo $var . '<br>';
}
As of PHP 5.3:
$new_urls = array_map(function($url) { // anonymous function
global $new_site;
$pathinfo = pathinfo($url);
$base = basename($pathinfo['dirname']);
$var = str_ireplace($url, $new_site . $base, $url);
return $var;
}, $urls);
echo implode('<br>', $new_urls);
Sorry by my last answer, you was right, the order was correct.
Try this one with pre_replace, I beleave could solve the problem:
$var = "http://mysite1.com/test/whatIwant/Idontwantthis";
$var = preg_replace("/http\:\/\/mysite1.com\/([^\/]+)\/?.*/", "http://myothersite.com/$1", $var);
echo $var;
I wish to have one string that contains for instance (mystring):
file config.php
$mystring = "hello my name is $name and i got to $school";
file index.php
include('config.php');
$name = $_GET['name'];
$school = $_GET['school'];
echo $mystring;
Would this work ? or are there any better ways
$string = 'Hello, my name is %s and I go to %s';
printf($string, $_GET['name'], $_GET['school']);
or
$string = 'Hello, my name is :name and I go to :school';
echo str_replace(array(':name', ':school'), array($_GET['name'], $_GET['school']), $string);
You can automate that last one with something like:
function value_replace($values, $string) {
return str_replace(array_map(function ($v) { return ":$v"; }, array_keys($values)), $values, $string);
}
$string = 'Hello, my name is :name and I go to :school';
echo values_replace($_GET, $string);
No it won't work.
You have to define $name first before using it in another variable
config.php should look like
<?php
$name = htmlspecialchars($_GET['name']);
$school = htmlspecialchars($_GET['school']);
$mystring = "hello my name is $name and i got to $school";
and index.php like
<?php
include('config.php');
echo $mystring;
Why didn't you try it?
demo:
http://sandbox.phpcode.eu/g/2d9e0.php?name=martin&school=fr.kupky
Alternatively, you can use sprintf like this:
$mystring = "hello my name is %s and i got to %s";
// ...
printf($mystring, $name, $school);
This works because your $mystring literal is using double quotes, if you'd used single quotes then it would not work.
