Convert a string to an array with a key - php

I have a string like this:
<enq fiscal="no" lastcommanderror="no" intransaction="no" lasttransactioncorrect="yes" />
I want to convert the above string into an array, and the output has to be this:
array(
['fiskal'] => "no",
['lastcommanderror'] => "no",
['intransaction'] => "no",
['lasttransactioncorrect'] => "yes"
)

You can use SimpleXMLElement:
$xmlString = '<enq fiscal="no" lastcommanderror="no" intransaction="no" lasttransactioncorrect="yes" />';
$array = ((array)(new SimpleXMLElement($xmlString)))["#attributes"];
var_dump($array);

You could make the string a json by replacing some characters then json_decode it.
$str = str_replace(['<enq ', ' />', '=', ' '], ['{"', '}', '":', ',"'], $str);
$arr = json_decode($str, true);

You can try this:
$string = '<enq fiscal="no" lastcommanderror="no" intransaction="no"
lasttransactioncorrect="yes" />';
// remove the <enq /> and whitespaces
$string = trim(ltrim(rtrim($string, '/>'), '<enq'));
$finalArray = [];
foreach (explode(' ', $string) as $value) {
$elements = explode('=', $value);
$finalArray[$elements[0]] = $elements[1];
}

str_replace() doesn't work using "(" and "[" PHP

This is my simple code function in php
function replaceCharact($input,$action){
$output_1 = str_replace('(', "%11%", $input);
$output_2 = str_replace(')', '%12%', $output_1);
$output_3 = str_replace('[', '%13%', $output_2);
$output_4 = str_replace(']', '%14%', $output_3);
$output_5 = str_replace('"', '%15%', $output_4);
$output_6 = str_replace('/', '%16%', $output_5);
$output_7 = str_replace('"\"', '%17%', $output_6);
$output_8 = str_replace('!', '%18%', $output_7);
$output_9 = str_replace('<', '%19%', $output_8);
$output_10 = str_replace('>', '%20%', $output_9);
return $output_10;
}
Only the "!"($output_8) change to %19%. The others output display nothing. Can you help me with this?
To simplify mass replacements using an array, try this...
$replacement = array(
'(' => "%11%",
')' => '%12%',
'[' => '%13%',
']' => '%14%'
// etc etc
);
$string = str_replace( array_keys( $replacement ), $replacement, $string );

php match a string from other string

I have a string as $test = 'aa,bb,cc,dd,ee' and other string as $match='cc'. I want the result as $result='aa,bb,dd,ee'.
I am not able to get te result as desired as not sure which PHP function can give the desired output.
Also if I have a string as $test = 'aa,bb,cc,dd,ee' and other string as $match='cc'. I want the result as $match=''. i.e if $match is found in $test then $match value can be skipped
Any help will be really appreciated.
You can try with:
$test = 'aa,bb,cc,dd,ee';
$match = 'cc';
$output = trim(str_replace(',,', ',', str_replace($match, '', $test), ','));
or:
$testArr = explode(',', $test);
if(($key = array_search($match, $testArr)) !== false) {
unset($testArr[$key]);
}
$output = implode(',', $testArr);
Try with preg_replace
$test = 'aa,bb,cc,dd,ee';
$match ='cc';
echo $new = preg_replace('/'.$match.',|,'.$match.'$/', '', $test);
Output
aa,bb,dd,ee
$test = 'aa,bb,cc,dd,ee';
$match='cc';
echo trim(str_replace(',,', ',' , str_replace($match,'',$test)),',');
DEMO
Try this:
$test = 'aa,bb,cc,dd,ee';
$match = 'cc';
$temp = explode(',', $test);
unset($temp[ array_search($match, $temp) ] );
$result = implode(',', $temp);
echo $result;

complex regex with preg_replace, replace a word not inside [ and ]

I'm having trouble finding a correct regex to achieve what I want.
I have a sentence like that :
Hi, my name is Stan, you are welcome, hello.
and I would like to transform it like that :
[hi|hello|welcome], my name is [stan|jack] you are [hi|hello|welcome] [hi|hello|welcome].
Right now my regex is half working, because somes words are not replaced, and those replaced are deleting some characters
Here is my test code
<?php
$test = 'Hi, my name is Stan, you are welcome, hello.';
$words = array(
array('hi', 'hello', 'welcome'),
array('stan', 'jack'),
);
$result = $test;
foreach ($words as $group) {
if (count($group) > 0) {
$replacement = '[' . implode('|', $group) . ']';
foreach ($group as $word) {
$result = preg_replace('#([^\[])' . $word . '([^\]])#i', $replacement, $result);
}
}
}
echo $test . '<br />' . $result;
Any help will be appreciated
The regex you are using is overcomplicated. You simply need to use a regex substitution using regular brackets ():
<?php
$test = 'Hi, my name is Stan, you are welcome, hello.';
$words = array(
array('hi', 'hello', 'welcome'),
array('stan', 'jack'),
);
$result = $test;
foreach ($words as $group) {
if (count($group) > 0) {
$imploded = implode('|', $group);
$replacement = "[$imploded]";
$search = "($imploded)";
$result = preg_replace("/$search/i", $replacement, $result);
}
}
echo $test . '<br />' . $result;
Your regular expression:
'#([^\[])' . $word . '([^\]])#i'
matches one character before and after $word as well. And as they do, they replace it. So your replacement string needs to reference these parts, too:
'$1' . $replacement . '$2'
Demo
preg_replace supports array as parameter. No need to iterate with a loop.
$s = array("/(hi|hello|welcome)/i", "/(stan|jack)/i");
$r = array("[hi|hello|welcome]", "[stan|jack]");
preg_replace($s, $r, $str);
or dynamically
$test = 'Hi, my name is Stan, you are welcome, hello.';
$s = array("hi|hello|welcome", "stan|jack");
$r = array_map(create_function('$a','return "[$a]";'), $s);
$s = array_map(create_function('$a','return "/($a)/i";'), $s);
echo preg_replace($s, $r, $str);
//[hi|hello|welcome], my name is [stan|jack], you are [hi|hello|welcome], [hi|hello|welcome].

str_replace doesn't work with foreach

My code:
$str = array(
'{$string1}' => 'anything2',
'{$string2}' => 'something1',
'{$string3}' => '...'
);
$final = "";
$text = $_POST['content'];
foreach( $str as $key => $val ) {
$final = str_replace($key, $val, $text);
}
My $text ofc. has {string1} , {string2} and {string3} itself, but it doesn't replace it with the values given in the array.
Why its not working?
This code does exactly what you need (without any extra loops):
$final = strtr($_POST['content'], $str);
use
$final = str_replace('{'.$key.'}', $val, $text);
Ref : http://php.net/manual/en/function.str-replace.php
Maybe the different enconding, try this:
$text = utf8_decode($_POST['content']);// or utf8_encode
before loop;
Good lucky!

Could you tell how to replace by regular expression

Could you tell how to replace string by preg-replace (need regular expression):
/user/{parent_id}/{action}/step/1
At the equivalent values of an array:
array('parent_id'=>32, 'action'=>'some');
To make:
/user/32/some/step/1
Addition
This is a typical problem, so I probably will not know what the names of variables come
You can use str_replace
For example:
str_replace(array("{parent_id}", "{action}"), array(32, 'some'), "/user/{parent_id}/{action}/step/1");
$arr = array('parent_id'=>32, 'action'=>'some');
$out = str_replace(array_keys($arr),array_values($arr),$in);
no need for regexps!
Say you have:
$arr = array('parent_id'=>32, 'action'=>'some');
$in = '/usr/{parent_id}/{action}/step/1';
This will replace the braces:
function bracelize($str) {
return '{' . $str . '}';
}
$search = array_map('bracelize', array_keys($arr));
$out = str_replace($search, $arr, $in);
Or if you are using PHP >= 5.3 you can use lambdas:
$search = array_map(function ($v) { return '{'.$v.'}';}, array_keys($arr));
$out = str_replace($search, $arr, $in);
$s = '/user/{parent_id}/{action}/step/1';
$replacement = array('parent_id'=>32, 'action'=>'some');
$res = preg_replace(array('/\\{parent_id\\}/', '/\\{action\\}/'), $replacement, $s);
Of course, you could just as well use str_replace (in fact, you ought to).
<?php
$string = '/usr/{parent_id}/{action}/step/1';
$pattern = array('#{parent_id}#', '#{action}#');
$values = array('32', 'some');
echo preg_replace($pattern, $values, $string);
?>
If your problem is not more complicated than this, i would recommend changing preg_replace to str_replace though.
EDIT: I see you don't know the variable names in advance. In which case you could do something like this.
<?php
function wrap_in_brackets(&$item)
{
$item = '{' . $item . '}';
return true;
}
$string = '/usr/{parent_id}/{action}/step/1';
$variables = array('parent_id' => 32, 'action' => 'some');
$keys = array_keys($variables);
array_walk($keys, 'wrap_in_brackets');
echo str_replace($keys, array_values($variables), $string);
?>
Expanding on mvds' answer:
$in = 'user/{parent_id}/{action}/step/1';
$arr = array('{parent_id}' => 32, '{action}' => 'some');
$out = str_replace(array_keys($arr), $arr, $in);
Or:
$in = 'user/{parent_id}/{action}/step/1';
$arr = array('parent_id' => 32, 'action' => 'some');
$arr[] = '';
$find = array_merge(array_keys($arr), array('{', '}'));
$out = str_replace($find, $arr, $in);
