I would like to be able to use this string to pull off a certain piece of data from a database '{my-id-1}' so basically if this is found in the text '{my-id-*}' then get the id (eg. if {is-id-1} then ID is 1) and then I can run some code with that ID.
So I've got it so I can get the ID from the braces, but I'm not sure how to replace that within the text.
<?php
$text = "test 1 dfhjsdh sdjkfhksdhfkj skjh {is-id-1} sdfhskdfh sdfsdjfhksd fjksdfhksd {is-id-2}";
preg_match_all('/{is-id-+(.*?)}/',$text, $matches);
print_r ($matches);
$replacewiththis = "this has been replaced, it was id: " . $idhere;
$text = preg_replace('/{is-id-+(.*?)}/', $replacewiththis, $text);
echo $text;
?>
The Array for the matches outputs:
Array (
[0] => Array (
[0] => {is-id-1}
[1] => {is-id-2}
)
[1] => Array (
[0] => 1
[1] => 2
)
)
I'm stuck now and not sure how to can process each of the braces. Can anyone give me a hand?
Thanks.
I am not sure I understood well what you want, but I think this is it:
foreach($matches[1] as $match){
$replacewiththis = "this has been replaced, it was id: $match";
$text=str_replace('{is-id-'.$match.'}', $replacewiththis, $text);
}
echo $text;

I have a variable (text) and it is updated with sentences every time there is an update. When i display this array it turns into 1 long sentence, and i want to break this up in single sentences for readability.
<?php
$pattern = '~\\d+-\\d+-\\d{4} // \\w+: ~ ';
$subject = '01-02-2015 // john: info text goes here 10-12-2015 // peter: some more info
';
$matches = array();
$result = preg_match_all ($pattern, $subject, $matches);
?>
Which gives this output:
$matches:
array (
0 =>
array (
0 => '01-02-2015 // john: ',
1 => '10-12-2015 // peter: ',
),
)
I'd like the output to be:
$matches:
array (
0 =>
array (
0 => '01-02-2015 // john: info text goes here',
1 => '10-12-2015 // peter: some more info',
),
)
I need the output to be like this so i can use a foreach loop to print each sentence.
ps. I'd like to try to get it to work this way first, because otherwise i'd need to change a lot of entries in the database.
pps. I'm also not a hero with regex as you can see, so i hope someone can help me out!
Just change your regex like below,
$pattern = '~\d+-\d+-\d{4} // \w+: .*?(?=\s\d+|$)~';
.*? will do a non-greedy match of zero or more characters until a space followed by digits or end of the line is reached.
DEMO
$str = "01-02-2015 // john: info text goes here 10-12-2015 // peter: some more info";
preg_match_all('~\d+-\d+-\d{4} // \w+: .*?(?=\s\d+|$)~', $str, $matches);
print_r($matches);
Output:
Array
(
[0] => Array
(
[0] => 01-02-2015 // john: info text goes here
[1] => 10-12-2015 // peter: some more info
)
)
I have a very long string of html. From this string I want to parse pairs of rus and eng names of cities. Example of this string is:
$html = '
Абакан
Хакасия республика
Абан
Красноярский край
Абатский
Тюменская область
';
My code is:
$subject = $this->html;
$pattern = '/<a href="([\/a-zA-Z0-9-"]*)">([а-яА-Я]*)/';
preg_match_all($pattern, $subject, $matches);
For trying I use regexer . You can see it here http://regexr.com/399co
On the test used global modifier - /g
Because of in PHP we can't use /g modifier I use preg_match_all function. But result of preg_match_all is very strange:
Array
(
[0] => Array
(
[0] => <a href="/forecasts5000/russia/republic-khakassia/abakan">Абакан
[1] => <a href="/forecasts5000/russia/krasnoyarsk-territory/aban">Абан
[2] => <a href="/forecasts5000/russia/tyumen-area/abatskij">Аба�
[3] => <a href="/forecasts5000/russia/arkhangelsk-area/abramovskij-ma">Аб�
)
[1] => Array
(
[0] => /forecasts5000/russia/republic-khakassia/abakan
[1] => /forecasts5000/russia/krasnoyarsk-territory/aban
[2] => /forecasts5000/russia/tyumen-area/abatskij
[3] => /forecasts5000/russia/arkhangelsk-area/abramovskij-ma
)
[2] => Array
(
[0] => Абакан
[1] => Абан
[2] => Аба�
[3] => Аб�
)
)
First of all - it found only first match (but I need to get array with all matches)
The second - result is very strange for me. I want to get the next result:
pairs of /forecasts5000/russia/republic-khakassia/abakan and Абакан
What do I do wrong?
Element 0 of the result is an array of each of the full matches of the regexp. Element 1 is an array of all the matches for capture group 1, element 2 contains capture group 2, and so on.
You can invert this by using the PREG_SET_ORDER flag. Then element 0 will contain all the results from the first match, element 1 will contain all the results from the second match, and so on. Within each of these, [0] will be the full match, and the remaining elements will be the capture groups.
If you use this option, you can then get the information you want with:
foreach ($matches as $match) {
$url = $match[1];
$text = $match[2];
// Do something with $url and $text
}
You can also use T-Regx library which has separate methods for each case :)
pattern('<a href="([/a-zA-Z0-9-"]*)">([а-яА-Я]*)')
->match($this->html)
->forEach(function (Match $match) {
$match = $match->text();
$group = $match->group(1);
echo "Match $match with group $group"
});
I also has automatic delimiters
i want to get a particular value from string in php. Following is the string
$string = 'users://data01=[1,2]/data02=[2,3]/*';
preg_replace('/(.*)\[(.*)\](.*)\[(.*)\](.*)/', '$2', $str);
i want to get value of data01. i mean [1,2].
How can i achieve this using preg_replace?
How can solve this ?
preg_replace() is the wrong tool, I have used preg_match_all() in case you need that other item later and trimmed down your regex to capture the part of the string you are looking for.
$string = 'users://data01=[1,2]/data02=[2,3]/*';
preg_match_all('/\[([0-9,]+)\]/',$string,$match);
print_r($match);
/*
print_r($match) output:
Array
(
[0] => Array
(
[0] => [1,2]
[1] => [2,3]
)
[1] => Array
(
[0] => 1,2
[1] => 2,3
)
)
*/
echo "Your match: " . $match[1][0];
?>
This enables you to have the captured characters or the matched pattern , so you can have [1,2] or just 1,2
preg_replace is used to replace by regular expression!
I think you want to use preg_match_all() to get each data attribute from the string.
The regex you want is:
$string = 'users://data01=[1,2]/data02=[2,3]/*';
preg_match_all('#data[0-9]{2}=(\[[0-9,]+\])#',$string,$matches);
print_r($matches);
Array
(
[0] => Array
(
[0] => data01=[1,2]
[1] => data02=[2,3]
)
[1] => Array
(
[0] => [1,2]
[1] => [2,3]
)
)
I have tested this as working.
preg_replace is for replacing stuff. preg_match is for extracting stuff.
So you want:
preg_match('/(.*?)\[(.*?)\](.*?)\[(.*?)\](.*)/', $str, $match);
var_dump($match);
See what you get, and work from there.
I want to find the no of occurences of a sustring(pattern based) inside another string.
For example:
$mystring = "|graboard='KERALA'||graboarded='KUSAT'||graboard='MG'";
I want to find the no of graboards present in the $mystring,
So I used the regex for this, But how will I find the no of occurrence?
If you must use a regex, preg_match_all() returns the number of matches.
Use preg_match_all:
$mystring = "|graboard='KERALA'||graboarded='KUSAT'||graboard='MG'";
preg_match_all("/(graboard)='(.+?)'/i", $mystring, $matches);
print_r($matches);
will yield:
Array
(
[0] => Array
(
[0] => graboard='KERALA'
[1] => graboard='MG'
)
[1] => Array
(
[0] => graboard
[1] => graboard
)
[2] => Array
(
[0] => KERALA
[1] => MG
)
)
So then you can use count($matches[1]) -- however, this regex may need to be modified to suit your needs, but this is just a basic example.
Just use preg_match_all():
// The string.
$mystring="|graboard='KERALA'||graboarded='KUSAT'||graboard='MG'";
// The `preg_match_all()`.
preg_match_all('/graboard/is', $mystring, $matches);
// Echo the count of `$matches` generated by `preg_match_all()`.
echo count($matches[0]);
// Dumping the content of `$matches` for verification.
echo '<pre>';
print_r($matches);
echo '</pre>';
I have a string contains the following pattern "[link:activate/$id/$test_code]" I need to get the word activate, $id and $test_code out of this when the pattern [link.....] occurs.
I also tried getting the inside items by using grouping but only gets active and $test_code couldn't get $id. Please help me to get all the parameter and action name in array.
Below is my code and output
Code
function match_test()
{
$string = "Sample string contains [link:activate/\$id/\$test_code] again [link:anotheraction/\$key/\$second_param]]] also how the other ationc like [link:action] works";
$pattern = '/\[link:([a-z\_]+)(\/\$[a-z\_]+)+\]/i';
preg_match_all($pattern,$string,$matches);
print_r($matches);
}
Output
Array
(
[0] => Array
(
[0] => [link:activate/$id/$test_code]
[1] => [link:anotheraction/$key/$second_param]
)
[1] => Array
(
[0] => activate
[1] => anotheraction
)
[2] => Array
(
[0] => /$test_code
[1] => /$second_param
)
)
Try this:
$subject = <<<'LOD'
Sample string contains [link:activate/$id/$test_code] again [link:anotheraction/$key/$second_param]]] also how the other ationc like [link:action] works
LOD;
$pattern = '~\[link:([a-z_]+)((?:/\$[a-z_]+)*)]~i';
preg_match_all($pattern, $subject, $matches);
print_r($matches);
if you need to have \$id and \$test_code separated you can use this instead:
$pattern = '~\[link:([a-z_]+)(/\$[a-z_]+)?(/\$[a-z_]+)?]~i';
Is this what you are looking for?
/\[link:([\w\d]+)\/(\$[\w\d]+)\/(\$[\w\d]+)\]/
Edit:
Also the problem with your expression is this part:
(\/\$[a-z\_]+)+
Although you have repeated the group, the match will only return one because it is still only one group declaration. The regex won't invent matching group numbers for you (Not that i've ever seen anyway).
