I have the following text string:
-asc100-17-asc100-17A-asc100-17BPH-asc100-17ASL
What regex code do I need to extract the values so that they appear in the matches array like this:
-asc100-17
-asc100-17A
-asc100-17BPH
-asc100-17ASL
Thanks in advance!
You may try this:
$str = "-asc100-17-asc100-17A-asc100-17BPH-asc100-17ASL";
preg_match_all('/-asc\d+-[0-9a-zA-Z]+/', $str, $matches);
// Print Result
print_r($matches);
Output:
Array
(
[0] => Array
(
[0] => -asc100-17
[1] => -asc100-17A
[2] => -asc100-17BPH
[3] => -asc100-17ASL
)
)
Based on the very limited information in your question, this works:
-asc100-17[A-Z]*
Debuggex Demo
If you want to capture the post -asc100- code, then use
-asc100-(17[A-Z]*)
Which places 17[the letters] into capture group one.
Might use preg_split with a lookahead as well for your scenario:
print_r(preg_split('/(?=-asc)/', $str, -1, PREG_SPLIT_NO_EMPTY));
Are you trying to break the string in an array? Then why regex is required? This function can handle what you want:
$arr = explode('-asc', '-asc100-17-asc100-17A-asc100-17BPH-asc100-17ASL');
foreach ($arr as $value) {
if(!empty($value)){
$final[] = '-asc'.$value;
}
}
print_r($final);
Output array : Array ( [0] => -asc100-17 [1] => -asc100-17A [2] => -asc100-17BPH [3] => -asc100-17ASL )

I did try but can't find or figure out regex for the following
Working in PHP need preg_split to work
{password=123456, telephone=9452979342}/{Accept=application/json, Authorization=Bearer kadaljdlkadjsdaskdjaskdasdf}
What I want is to split this string into array like this:
Split by '/' in middle
[0] => {password=123456, telephone=9452979342}
[2] => {Accept=application/json, Authorization=Bearer kadaljdlkadjsdaskdjaskdasdf}
Select between {*}
[0] => password=123456, telephone=9452979342
[2] => Accept=application/json, Authorization=Bearer kadaljdlkadjsdaskdjaskdasdf
As per your way , you may try the following approach as well
$re = '/\}\/\{/m';
$str = '{password=123456, telephone=9452979342}/{Accept=application/json, Authorization=Bearer kadaljdlkadjsdaskdjaskdasdf}';
$arr=preg_split($re,$str);
$cnt=0;
foreach($arr as $values)
$arr[$cnt++]=preg_replace('/[{}]/','',$values);
print_r($arr);
run here
Is that what you want:
$str = "{password=123456, telephone=9452979342}/{Accept=application/json, Authorization=Bearer kadaljdlkadjsdaskdjaskdasdf}";
preg_match('~\{(.+?)\}/\{(.+?)\}~', $str, $matches);
print_r($matches);
Output:
Array
(
[0] => {password=123456, telephone=9452979342}/{Accept=application/json, Authorization=Bearer kadaljdlkadjsdaskdjaskdasdf}
[1] => password=123456, telephone=9452979342
[2] => Accept=application/json, Authorization=Bearer kadaljdlkadjsdaskdjaskdasdf
)
I have a string like this:
string="59|https://site59.com20|https://site20.com30|https://site30.com16|https://site15.com66|https://site66.com29|https://site29.com";
-Just one example is not just that.
I did this regular expression
preg_match_all("/[0-9][0-9](?:\|)(?:https\:\/\/)(.*?)/", string, string2);
But it only takes number|https:
I wonder how do I get it and only stop when you find the next occurrence of the regular expression and separate it into different arrays
Try this:
$string="59|https://site59.com20|https://site20.com30|https://site30.com16|https://site15.com66|https://site66.com29|https://site29.com";
preg_match_all("/(?:[0-9][0-9](?:\|)(?:https\:\/\/)(.*?)(?=[\d][\d]\||$))|([\d][\d]\|.*)/", $string, $matches);
Results array in $matches:
[0] => 59|https://site59.com
[1] => 20|https://site20.com
[2] => 30|https://site30.com
[3] => 16|https://site15.com
[4] => 66|https://site66.com
[5] => 29|https://site29.com
Try using preg_split
<?php
$string="59|https://site59.com20|https://site20.com30|https://site30.com16|https://site15.com66|https://site66.com29|https://site29.com";
$sites = preg_split("/[0-9][0-9](?:\|)(?:https\:\/\/)(.*?)/", $string);
foreach($sites as $site){
echo "https://$site\n";
}
https://site59.com
https://site20.com
https://site30.com
https://site15.com
https://site66.com
https://site29.com
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 the following string
{item1}home::::Home{/item1}{item2}contact_us::::Contact Us{/item2}{item3}.....
and so it goes on.
I need to split the string the following way
1=>{item1}home::::Home{/item1}
2=>{item2}contact_us::::Contact Us{/item2}
Is there a way?
$input = '{item1}home::::Home{/item1}{item2}contact_us::::Contact Us{/item2}{item3}.....';
$regex = '/{(\w+)}.*{\/\1}/';
preg_match_all($regex, $input, $matches);
print_r($matches[0]);
You could do it like this:
$text = "{item1}home::::Home{/item1}{item2}contact_us::::Contact Us{/item2}{item3}.....){/item3}";
preg_match_all('/{item\d}.+?{\/item\d}/', $text, $results);
var_dump($results) would produce:
Array
(
[0] => Array
(
[0] => {item1}home::::Home{/item1}
[1] => {item2}contact_us::::Contact Us{/item2}
[2] => {item3}.....){/item3}
)
)
Use preg_split() with the regex pattern /{.*?}.*?{\/.*?}/
