I want remove unnecessary text from my string variable. I have variable like $from which contains value like 123456#blog.com. I want only 123456 from it. I have checked some example for trim but does not getting proper idea for do it. Let me know if someone can help me for do it. Thanks
You can split the string on the # symbol like so:
$str = "123456#blog.com";
// here you split your string into pieces before and after #
$pieces = explode("#",$str);
// here you echo your first piece
echo $pieces['0'];
Demo
You can use explode() for splitting the string.
Syntax:
explode('separator', string);
$result= explode("#", '123456#blog.com');
print_r($result);
Output:
Array
(
[0] => 123456
[1] => blog.com
)

I have a string contain emoji.
I want extract emoji's from that string,i'm using below code but it doesn't what i want.
$string = "😃 hello world 🙃";
preg_match('/([0-9#][\x{20E3}])|[\x{00ae}\x{00a9}\x{203C}\x{2047}\x{2048}\x{2049}\x{3030}\x{303D}\x{2139}\x{2122}\x{3297}\x{3299}][\x{FE00}-\x{FEFF}]?|[\x{2190}-\x{21FF}][\x{FE00}-\x{FEFF}]?|[\x{2300}-\x{23FF}][\x{FE00}-\x{FEFF}]?|[\x{2460}-\x{24FF}][\x{FE00}-\x{FEFF}]?|[\x{25A0}-\x{25FF}][\x{FE00}-\x{FEFF}]?|[\x{2600}-\x{27BF}][\x{FE00}-\x{FEFF}]?|[\x{2900}-\x{297F}][\x{FE00}-\x{FEFF}]?|[\x{2B00}-\x{2BF0}][\x{FE00}-\x{FEFF}]?|[\x{1F000}-\x{1F6FF}][\x{FE00}-\x{FEFF}]?/u', $string, $emojis);
i want this:
$emojis = ["😃", "🙃"];
but return this:
$emojis = ["😃"]
and also if:
$string = "😅😇☝🏿"
it return only first emoji
$emoji = ["😅"]
Try looking at preg_match_all function. preg_match stops looking after it finds the first match, which is why you're only ever getting the first emoji back.
Taken from this answer:
preg_match stops looking after the first match. preg_match_all, on the other hand, continues to look until it finishes processing the entire string. Once match is found, it uses the remainder of the string to try and apply another match.
http://php.net/manual/en/function.preg-match-all.php
So your code would become:
$string = "😃 hello world 🙃";
preg_match_all('/([0-9#][\x{20E3}])|[\x{00ae}\x{00a9}\x{203C}\x{2047}\x{2048}\x{2049}\x{3030}\x{303D}\x{2139}\x{2122}\x{3297}\x{3299}][\x{FE00}-\x{FEFF}]?|[\x{2190}-\x{21FF}][\x{FE00}-\x{FEFF}]?|[\x{2300}-\x{23FF}][\x{FE00}-\x{FEFF}]?|[\x{2460}-\x{24FF}][\x{FE00}-\x{FEFF}]?|[\x{25A0}-\x{25FF}][\x{FE00}-\x{FEFF}]?|[\x{2600}-\x{27BF}][\x{FE00}-\x{FEFF}]?|[\x{2900}-\x{297F}][\x{FE00}-\x{FEFF}]?|[\x{2B00}-\x{2BF0}][\x{FE00}-\x{FEFF}]?|[\x{1F000}-\x{1F6FF}][\x{FE00}-\x{FEFF}]?/u', $string, $emojis);
print_r($emojis[0]); // Array ( [0] => 😃 [1] => 🙃 )
I want to extract the dimension from this given string.
$str = "enough for hitting practice. The dimension is 20'X10' *where";
I expect 20'X10' as the result.
I tried with the following code to get the number before and after the string 'X. But it is returning an empty array.
$regexForMinimumPattern ='/((?:\w+\W*){0,1})\'X\b((?:\W*\w+){0,1})/i';
preg_match_all ($regexForMinimumPattern, $str, $minimumPatternMatches);
print_r($minimumPatternMatches);
Can anyone please help me to fix this? Thanks in advance.
Just remove the \b from your pattern (and append a \' in the end if you want the trailing quote):
$regexForMinimumPattern ='/((?:\w+\W*){0,1})\'X((?:\W*\w+){0,1})\'/i';
NB: \b is the meta-character for word-boundaries, you don't need it here.
Assuming that the format of the string we want is 00'X00 :
$regexForMinimumPattern ='/[0-9]{1,2}\'X[0-9]{1,2}/i';
this gives you a result like
Array ( [0] => Array ( [0] => 20'X10 ) )
So: can a simple preg_replace()do that? Perhaps...
<?php
$str = "enough for hitting practice. The dimension is 20'X10' *where";
$dim = preg_replace("#(.*?)(\d*?)(\.\d*)?(')(X)(\d*?)(\.\d*)?(')(.+)#i","$2$3$4$5$6$7", $str);
var_dump($dim); //<== YIELDS::: string '20'X10' (length=6)
You may try it out Here.
I am trying to generate a regex that allows me to do the following:
I have a string containing several terms, all which are alphanumeric and maybe some of these special characters: +.#
They are separated by a comma as well.
This is kind of how it looks like:
$string = 'Term1,Term2,Term3,Term4'; ... And so on... (around 60 terms)
I want to be able to get each term and assign it to a variable, because I want to employ a second Regex to a long string, for example:
$secondString = 'This string may contain some terms, such as Term1, or maybe Term2';
So pretty much I want to be able to check if any of the terms in the first string are present in the second string.
I watched the following tutorial:
https://www.youtube.com/watch?v=EkluES9Rvak
But I just seem to not be able to come up with something.
Thank you so much for your help in advance!
Cheers!
You can use array_intersect function after splitting strings into tokens:
$string = 'Term1,Term2,Term3,Term4';
$secondString = 'This string may contain some terms, such as Term1, or maybe Term2';
$arr1 = explode(',', $string);
$arr2 = preg_split('/[,\h]+/', $secondString);
$arr = array_intersect(array_map('strtolower', $arr1), array_map('strtolower', $arr2));
print_r($arr);
Output:
Array
(
[0] => Term1
[1] => Term2
)
I need help to find out the strings from a text which starts with # and till the next immediate space by preg_match in php
Ex : I want to get #string from this line as separate.
In this example, I need to extract "#string" alone from this line.
Could any body help me to find out the solutions for this.
Thanks in advance!
PHP and Python are not the same in regard to searches. If you've already used a function like strip_tags on your capture, then something like this might work better than the Python example provided in one of the other answers since we can also use look-around assertions.
<?php
$string = <<<EOT
I want to get #string from this line as separate.
In this example, I need to extract "#string" alone from this line.
#maybe the username is at the front.
Or it could be at the end #whynot, right!
dog#cat.com would be an e-mail address and should not match.
EOT;
echo $string."<br>";
preg_match_all('~(?<=[\s])#[^\s.,!?]+~',$string,$matches);
print_r($matches);
?>
Output results
Array
(
[0] => Array
(
[0] => #string
[1] => #maybe
[2] => #whynot
)
)
Update
If you're pulling straight from the HTML stream itself, looking at the Twitter HTML it's formatted like this however:
<s>#</s><b>UserName</b>
So to match a username from the html stream you would match with the following:
<?php
$string = <<<EOT
<s>#</s><b>Nancy</b> what are you on about?
I want to get <s>#</s><b>string</b> from this line as separate. In this example, I need to extract "#string" alone from this line.
<s>#</s><b>maybe</b> the username is at the front.
Or it could be at the end <s>#</s><b>WhyNot</b>, right!
dog#cat.com would be an e-mail address and should not match.
EOT;
$matchpattern = '~(<s>(#)</s><b\>([^<]+)</b>)~';
preg_match_all($matchpattern,$string,$matches);
$users = array();
foreach ($matches[0] as $username){
$cleanUsername = strip_tags($username);
$users[]=$cleanUsername;
}
print_r($users);
Output
Array
(
[0] => #Nancy
[1] => #string
[2] => #maybe
[3] => #WhyNot
)
Just do simply:
preg_match('/#\S+/', $string, $matches);
The result is in $matches[0]
How could I Separate characters and numbers from an input and store as separate variables php for example my input string is as $str="abc567" and i need to separate it as $str1="abc" and $str2="567".
You can use preg_split using lookahead and lookbehind:
print_r(preg_split('#(?<=\d)(?=[a-z])#i', "abc567"));
prints
Array
(
[0] => abc
[1] => 567
)
I hope this helps :)
Regards.
By using preg_split, you can pass a regex string. This will return all the patterns that match a given regex string, and you can use that to store the various values into their respective variables.
Notice there is no code here; you should be trying to work these things out yourself.
well preg_split will help you.
Official Document : http://php.net/manual/en/function.preg-split.php
Example
echo "<pre>";
print_r(preg_split('#(?<=\d)(?=[a-z])#i', "abc567"));
echo "</pre>";
above will out put.
Array
(
[0] => abc
[1] => 567
)
try this
$str="abc567";
preg_match_all('/(\d)|(\w)/', $str, $matches);
$numbers = implode($matches[1]);
$characters = implode($matches[2]);
If your are wanting all numbers and all letters in separate variables you can use:
$your_var = "abc567";
$str_letters = preg_replace('/[a-z]/', "", $your_var);
$str_numbers = preg_replace('/[0-9]/', "", $your_var);
Beware that if $your_var = abc7567d64h num = 756764 letters = abcdh
