Ok to be clear ill give an example
$email = 'name#example.com';
$domain = strstr($email, '#');
echo $domain; // prints #example.com
$user = strstr($email, '#', true); // As of PHP 5.3.0
echo $user; // prints name
as it says, it prints what before '#' using true, and blank to print what follows #
im looking for a function to print # itself by giving it 2 strings and grab what between them
like this
$string= 'someXthing';
$tograb = phpfunction("some","thing");
echo $tograb; // should be printing X
^ this doesnt work, im just writing it to explain
I dont know of a native function that does that but you can use regular expression
$string= 'someXthing';
preg_match("/some(.*)thing/",$string,$matches);
var_dump($matches[1]);
Read More about preg_match
From internet
function GetBetween($content,$start,$end){
$r = explode($start, $content);
if (isset($r[1])){
$r = explode($end, $r[1]);
return $r[0];
}
return '';
}
Original code
For the example you said, you can use strpos to print X like this:
$string = 'someXthing';
$start = strpos($string, "some") + strlen("some");
$end = strpos($string, "thing", $start);
$tograb = substr($string, $start, $end - $start);
echo $tograb;
and X will be printed.

i want to find the text between title tags. how to do this?
for example in this page title contains 'One Punch Man - MyAnimeList.net' i want to get that
Just use string replace function:
$string = '<BoomBox>';
$string = str_replace('<', '', $string);
$string = str_replace('>', '', $string);
echo $string; // output: Boombox
http://php.net/manual/en/function.str-replace.php
You edited your answer, and we can now see you are dealing with XML/HTML. It's always better to work with the DOM classes. Never use regex! There is a famous Stack Overflow post explaining why never to parse html with regex. Try this solution instead:
<?php
$dom = new DOMDocument();
$dom->loadHTML('<title>BoomBox</title>');
echo $dom->getElementsByTagName('title')->item(0)->textContent;
http://php.net/manual/en/class.domdocument.php
http://php.net/manual/en/class.domnode.php
See it working here https://3v4l.org/EjPQd
You can use preg_replace();, or strip_tags();.
Example preg_replace();:
$str = '> One Punch Man';
$new = preg_replace('/[^a-zA-Z0-9 \p{L}]/m', '', $str);
echo $new;
Output: One Punch Man
Above example will only allow a-z, A-Z and 0-9. You can expand this.
Example strip_tags();:
$str = '<title> BoomBox </title>';
$another = strip_tags($str);
echo $another;
Output: BoomBox
Documentation:
http://php.net/manual/en/function.preg-replace.php // preg_replace();
http://php.net/manual/en/function.strip-tags.php // strip_tags();
You can also use a single call to str_replace with the ['<','>'] as the search argument:
$string = '<BoomBox>';
echo str_replace(['<', '>'], '', $string) . PHP_EOL;
// => Boombox
Or, you may use a regex with preg_replace (especially, if you plan on adding more restrictions for in-context matching to it):
echo preg_replace('~[<>]~', '', $string);
// => Boombox
See the PHP demo.
It might seem easy to do but I have trouble extracting this string. I have a string that has # tags in it and I'm trying to pull the tags maps/place/Residences+Jardins+de+Majorelle/#33.536759,-7.613825,17z/data=!3m1!4b1!4m2!3m1!1s0xda62d6053931323:0x2f978f4d1aabb1aa
And here is what I want to extract 33.536759,-7.613825,17z :
$var = preg_match_all("/#(\w*)/",$path,$query);
Any way I can do this? Much appreciated.
Change your regex to this one: /#([\w\d\.\,-]*)/.
This will return the string beginning with #.
$string = 'maps/place/Residences+Jardins+de+Majorelle/#33.536759,-7.613825,17z/data=!3m1!4b1!4m2!3m1!1s0xda62d6053931323:0x2f978f4d1aabb1aa';
$string = explode('/',$string);
//$coordinates = substr($string[3], 1);
//print_r($coordinates);
foreach ($string as $substring) {
if (substr( $substring, 0, 1 ) === "#") {
$coordinates = $substring;
}
}
echo $coordinates;
This is working for me:
$path = "maps/place/Residences+Jardins+de+Majorelle/#33.536759,-7.613825,17z/data=!3m1!4b1!4m2!3m1!1s0xda62d6053931323:0x2f978f4d1aabb1aa";
$var = preg_match_all("/#([^\/]+)/",$path,$query);
print $query[1][0];
A regex would do.
/#(-*\d+\.\d+),(-*\d\.\d+,\d+z*)/
If there is only one # and the string ends with / you can use the following code:
//String
$string = 'maps/place/Residences+Jardins+de+Majorelle/#33.536759,-7.613825,17z/data=!3m1!4b1!4m2!3m1!1s0xda62d6053931323:0x2f978f4d1aabb1aa';
//Save string after the first #
$coordinates = strstr($string, '#');
//Remove #
$coordinates = str_replace('#', '', $coordinates);
//Separate string on every /
$coordinates = explode('/', $coordinates );
//Save first part
$coordinates = $coordinates[0];
//Do what you want
echo $coordinates;
do like this
$re = '/#((.*?),-(.*?),)/mi';
$str = 'maps/place/Residences+Jardins+de+Majorelle/#33.536759,-7.613825,17z/data=!3m1!4b1!4m2!3m1!1s0xda62d6053931323:0x2f978f4d1aabb1aa';
preg_match_all($re, $str, $matches);
echo $matches[2][0].'<br>';
echo $matches[3][0];
output
33.536759
7.613825
How can I extract 4 from this string?
$string = "Rank_1:1:4";
I'm trying to get pagerank from Googles server, and the last value (4) is the actual pagerank.
Try
$string = "Rank_1:1:4";
$data = explode(':',$string);
echo end($data);
EDIT
as per #MichaelHampton, if they add more fields later, then use as below
$string = "Rank_1:1:4";
$data = explode(':',$string);
echo $data[2];
PHP has so many string function you can use ...
Variables
$find = ":";
$string = "Rank_1:1:4";
Using substr
echo substr($string, strrpos($string, $find) + 1);
Using strrchr
echo ltrim(strrchr($string, $find),$find);
$pattern = '/:\d+$/';
preg_match($pattern, $string, $matches);
$rank = substr($matches[0],1);
I need to convert lib_someString to someString inside a block of text using str_replace [not regex].
Here's an example to give an exact sense what I mean: lib_12345 => 12345. I need to do this for a bunch of instances in a block of text.
Below is my attempt. Problem I'm getting is that my function is not doing anything (I just get lib_id returned).
function extractLibId($val){ // function to get the "12345" in the above example
$lclRetVal = substr($val, 5, strlen($val));
return $lclRetVal;
}
function Lib($text){ // does the replace for all lib_ instances in the text
$lclVar = "lib_";
$text = str_replace($lclVar, "<a href='".extractLibId($lclVar)."'>".extractLibId($lclVar)."</a>", $text);
return $text;
}
Regexp gonna be faster and more clear, you will have no need to call your function for every possible 'lib_' string:
function Lib($text) {
$count = null;
return preg_replace('/lib_([0-9]+)/', '$1', $text, -1, $count);
}
$text = 'some text lib_123123 goes here lib_111';
$text = Lib($text);
Without regexp, but every time Lib2 will be called somewhere will die cute kitten:
function extractLibId($val) {
$lclRetVal = substr($val, 4);
return $lclRetVal;
}
function Lib2($text) {
$count = null;
while (($pos = strpos($text, 'lib_')) !== false) {
$end = $pos;
while (!in_array($text[$end], array(' ', ',', '.')) && $end < strlen($text))
$end++;
$sub = substr($text, $pos, $end - $pos);
$text = str_replace($sub, ''.extractLibId($sub).'', $text);
}
return $text;
}
$text = 'some text lib_123123 goes here lib_111';
$text = Lib2($text);
Use preg_replace.
Although it is possible to do what you need without regular expressions, you say you don't want to use them because of performance reasons. I doubt the other solution will be faster, so here is a simple regex to benchmark against:
echo preg_replace("/lib_(\w+)/", '$1', $str);
As shown here: http://codepad.org/xGj78r9r
Ignoring how ridiculous area of optimizing this is, even the simplest implementation with minimal validation already takes only 33% less time than a regex
<?php
function uselessFunction( $val ) {
if( strpos( $val, "lib_" ) !== 0 ) {
return $val;
}
$str = substr( $val, 4 );
return "{$str}";
}
$l = 100000;
$now = microtime(TRUE);
while( $l-- ) {
preg_replace( '/^lib_(.*)$/', "$1", 'lib_someString' );
}
echo (microtime(TRUE)-$now)."\n";
//0.191093
$l = 100000;
$now = microtime(TRUE);
while( $l-- ) {
uselessFunction( "lib_someString" );
}
echo (microtime(TRUE)-$now);
//0.127598
?>
If you're restricted from using a regex, you're going to have difficult time searching for a string you describe as "someString", i.e. not precisely known in advance. If you know the string is exactly lib_12345, for example, then set $lclVar to that string. On the other hand, if you don't know the exact string in advance, you'll have to use a regex via preg_replace() or a similar function.
Does anybody have the exact name of the function Drupal uses to turn the following string:
"Hello, how are you. Some more text."
into
"Hello, how..."
I.e. The function that's used to cut off a sentence after x words, and then add an elipsis. Alternatively, if anybody has a php snippet that does this, that would be great too!
function getFirstWords($string, $words = 1)
{
$string = explode(' ', $string);
if (count($string) > $words)
{
return implode(' ', array_slice($string, 0, $words)) . '...';
}
return implode(' ', $string);
}
echo getFirstWords('Hello, how are you. Some more text.', 2); // Hello, how...
It seems to be truncate_utf8() in unicode.inc.
You can use function views_trim_text($alter, $value)
view more detail https://api.drupal.org/api/views/views.module/function/views_trim_text/7
$alter['html'] = TRUE;
$alter['max_length'] = 200;
$alter['word_boundary'] = TRUE;
$alter['ellipsis'] = TRUE;
print views_trim_text($alter, $output);
