I'm new to PHP and I have a problem.
I need delete all chars since a symbol (Sorry for my bad english , i'm from argentina)
I have this text :
3,94€
And I need the text is as follows:
3,94
I tried this by multiple ways but it didn't work.
There are a few ways you can do this:
Using strpos:
$string = '3,94€';
echo substr($string, 0, strpos($string, '&'));
or using strstr:
// Requires PHP 5.3+ due to the true (before_needle) parameter
$string = '3,94€';
echo strstr($string, '&', true);
or using explode:
// Useful if you need to keep the € part for later
$string = '3,94€';
list($part_a, $part_b) = explode('&', $string);
echo $part_a;
or using reset:
$string = '3,94€';
echo reset(explode('&', $string));
The best suited in your case would be to use strpos to find the first occurrence of & in the string, and then use substr to return the string from the begining until the value returned by strpos.
Another posibility is clean the number and then round it:
<?php
//Option 1: with regular expresions:
$val = '3,94€';
$res = preg_replace('/[^0-9.,]/','',$val);
var_dump($res);
//Option 2: with filter functions:
$res2 = filter_var($val, FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND);
var_dump($res2);
//Output: 3,948364
//If you want to round it:
$res = substr($res, 0, 4);
var_dump($res);
?>
You can use regex: https://regex101.com/r/uY0kH3/1
It will work in preg_match() function.
You could use str_replace.
<?php
$string = 3,94€
$final = str_replace('€' ,'', $string);
echo $final;

I want to replace a letter with another character and also add 1 value more.
I mean the values are dynamic
For example I have H9 ,i want to replace as G10 .
Similarly...
H2 as G3
H6 as G7
Is it possible to use str_replace() for this ?
I got this one which works for me:
$old_string = "H2";
$new_string = "G" . (substr($old_string, 1) + 1);
echo $new_string;
Works fine for me. This is just for one value, but i guess you can loop through an array too, just have to modify the values like this
foreach($old_values as $v) {
$new_values[] = "G" . (substr($v, 1) + 1);
}
So you could save all the values into the $new_string array
Try This
<?php
$str = "H25";
preg_match_all('!\d+!', $str, $matches);
$str = str_replace($matches['0']['0'], $matches['0']['0']+1, $str, $count);
echo $str;
?>
Of course you can use str_replace()
Use
$new = array("G10", "G3", "G7");
$old = array("H9", "H2", "H6");
$string = str_replace($old, $new, $string);
where $string is your original string.
More simpler way... (Generalized Solution)
<?php
$str='G10';
preg_match('!\d+!', $str, $digit); //<---- Match the number
$str = substr($str,0,1); //<--- Grab the first char & increment it in the second line
echo ++$str.($digit[0]+1); //"prints" H11

I'm trying to split a php string in to parts the first one include the delimiter but the second one doesn't
$string = "abc==123";
What I want exactly is to get
$string['0'] = "abc==";
$string['1'] = "123";
Thanks for help
Simple enough
<?php
$string = explode("==", $string);
$string[0] .= "==";
?>
I believe you want the function strstr
http://us1.php.net/strstr
You can use PHP's explode function,
$data = "abc==123";
$result = explode("==", $data);
echo $result[0]. "==";
echo $result[1];
I have string that will look like this:
$string = "hello, my, name, is, az";
Now I just wanna echo whatever is there before first comma. I have been using following:
echo strstr($this->tags, ',', true);
and It has been working great, but the problem it only works php 5.3.0 and above. I am currently on PHP 5.2.
I know this could be achieve through regular express by pregmatch but I suck at RE.
Can someone help me with this.
Regards,
<?php
$string = "hello, my, name, is, az";
echo substr($string, 0, strpos($string, ','));
You can (and should) add further checks to avoid substr if there's no , in the string.
Use explode than,
$arr = explode(',', $string,2);
echo $arr[0];
You can explode this string using comma and read first argument of array like this
$string = "hello, my, name, is, az";
$str = explode(",", $string, 2);
echo $str[0];
$parts = explode(',',$string);
echo $parts[0];
You can simple use the explode function:
$string = "hello, my, name, is, az";
$output = explode(",", $string);
echo $output[0];
Too much explosives for a small work.
$str = current(explode(',', $string));
How can I use str_replace method for replacing a specified portion(between two substrings).
For example,
string1="www.example.com?test=abc&var=55";
string2="www.example.com?test=xyz&var=55";
I want to replace the string between '?------&' in the url with ?res=pqrs&. Are there any other methods available?
You could use preg_replace to do that, but is that really what you are trying to do here?
$str = preg_replace('/\?.*?&/', '?', $input);
If the question is really "I want to remove the test parameter from the query string" then a more robust alternative would be to use some string manipulation, parse_url or parse_str and http_build_query instead:
list($path, $query) = explode('?', $input, 2);
parse_str($query, $parameters);
unset($parameters['test']);
$str = $path.'?'.http_build_query($parameters);
Since you're working with URL's, you can decompose the URL first, remove what you need and put it back together like so:
$string1="www.example.com?test=abc&var=55";
// fetch the part after ?
$qs = parse_url($string1, PHP_URL_QUERY);
// turn it into an associative array
parse_str($qs, $a);
unset($a['test']); // remove test=abc
$a['res'] = 'pqrs'; // add res=pqrs
// put it back together
echo substr($string1, 0, -strlen($qs)) . http_build_query($a);
There's probably a few gotchas here and there; you may want to cater for edge cases, etc. but this works on the given inputs.
Dirty version:
$start = strpos($string1, '?');
$end = strpos($string1, '&');
echo substr($string1, 0, $start+1) . '--replace--' . substr($string1, $end);
Better:
preg_replace('/\?[^&]+&/', '?--replace--&', $string1);
Depending on whether you want to keep the ? and &, the regex can be mofidied, but it would be quicker to repeat them in the replaced string.
Think of regex
<?php
$string = 'www.example.com?test=abc&var=55';
$pattern = '/(.*)\?.*&(.*)/i';
$replacement = '$1$2';
$replaced = preg_replace($pattern, $replacement, $string);
?>
I have a string that looks a little like this, world:region:bash
It divides folder names, so i can create a path for FTP functions.
However, i need at some points to be able to remove the last part of the string, so, for example
I have this world:region:bash
I need to get this world:region
The script wont be able to know what the folder names are, so some how it needs to be able to remove the string after the last colon.
$res=substr($input,0,strrpos($input,':'));
I should probably highlight that strrpos not strpos finds last occurrence of a substring in given string
$tokens = explode(':', $string); // split string on :
array_pop($tokens); // get rid of last element
$newString = implode(':', $tokens); // wrap back
You may want to try something like this:
<?php
$variable = "world:region:bash";
$colpos = strrpos($variable, ":");
$result = substr($variable, 0, $colpos);
echo $result;
?>
Or... if you create a function using this information, you get this:
<?php
function StrRemoveLastPart($string, $delimiter)
{
$lastdelpos = strrpos($string, $delimiter);
$result = substr($string, 0, $lastdelpos);
return $result;
}
$variable = "world:region:bash";
$result = StrRemoveLastPart($variable, ":");
?>
Explode the string, and remove the last element.
If you need the string again, use implode.
$items = array_pop(explode(':', $the_path));
$shotpath = implode(':', $items);
Use regular expression /:[^:]+$/, preg_replace
$s = "world:region:bash";
$p = "/:[^:]+$/";
$r = '';
echo preg_replace($p, $r, $s);
demo
Notice how $ which means string termination, is made use of.
<?php
$string = 'world:region:bash';
$string = implode(':', explode(':', $string, -1));
