How to limit the elements created by explode()
(4 answers)
Closed 7 months ago.
I have a String "Hello I am apple"
I want to split to two string
str1 = "Hello"
str2 = "I am apple"
so just simply split by the first space, then the following words will be in one string
Explode function has a 3rd parameter for that:
limit
If limit is set and positive, the returned array will contain a maximum of limit elements with the last element containing the rest of string.
http://php.net/explode
list($str1, $str2) = explode(" ", $str, 2);
Same result also can be achieved by following code....
<?php
$str = "Hello I am Apple";
$str_con = explode(" ",$str,2);
echo $str_con[0];
echo $str_con[1];
?>

How substr function works? [closed]
(3 answers)
Closed 4 years ago.
I am trying to get "pa" from "a(bcdefghijkl(mno)pa)q".
This is my code for exampe:
$s = "a(bcdefghijkl(mno)pa)q";
$mystring = substr($s,14,15);
echo $mystring;
outputs is:
mno)pa)q
You have use right code but the second parameter is wrong. use this one below
$s = "a(bcdefghijkl(mno)pa)q";
$mystring = substr($s,14,2);
echo $mystring;
In substr function:
first parameter means from which position of string starts.
and the second parameter means how many characters you have want.
$s = "a(bcdefghijkl(mno)pa)q";
$mystring = substr($s,-4,2);
echo $mystring;
Try this

Insert string at specified position

separate string in two by given position

Closed 4 years ago.
I want to explode a string or an integer and separate it by a space.
E.g., I have this int 12345678, and I want its numbers to become like 123 45678. I want the first three numbers separated. Can someone give me a clue or hint in how to achieve this, like what function to use in PHP? I think using an explode will not work here because the explode function needs a separator.
You can use substr_replace() - Replace text within a portion of a string.
echo substr_replace(1234567, " ", 3, 0); // 123 4567
https://3v4l.org/9CFlX
You could use substr() :
$str = "12345678" ;
echo substr($str,0,3)." ".substr($str, 3); // "123 45678"
Also works with an integer :
$int = 12345678 ;
echo substr($int,0,3)." ".substr($int, 3); // "123 45678"
This problem will solve by using substr().
The substr() function returns a part of a string.
Syntax: substr(string,start,length)
Example:
$value = "12345678";
echo substr($value,0,3)." ".substr($value, 3);
Output: 123 45678

Extract floating point numbers from a delimited string in PHP
(6 answers)
Closed 6 years ago.
I am trying to extract any number out from a string (with or without decimal) and dump that into an array. Below is my code
$matches = array();
$str = "I have string of 21.11 out of 30";
preg_match_all("/\d+/",$str,$matches);
echo var_dump($matches);
The current output has 3 elements below:
21
11
30
But I expect to output only 2 elements below:
21.11
30
How do I change my regex?
You should use this regex (add dot in character class) :
$matches = array();
$str = "I have string of 21.11 out of 30";
preg_match_all("/[\d\.]+/",$str,$matches);
var_dump($matches);
Test it (Ctrl + Enter)

PHP substring extraction. Get the string before the first '/' or the whole string
(14 answers)
Closed 8 months ago.
$A=123132,32132,123132321321,3
$B=1,32,99
$C=456,98,89
$D=1
I want to cut string after first comma
output. . .
$A=123132
$B=1
$C=456
$D=1
$newA = current(explode(",", $A));
from: PHP substring extraction. Get the string before the first '/' or the whole string
You can do this with strpos to get the position of the first comma, and substr to get the value prior to it:
<?php
$val='123132,32132,123132321321,3';
$a=substr($val,0,strpos($val,','));
echo $a;
?>
Output:
123132
There are a number of ways to accomplish this:
substr($A,0,strpos($A,","))
or
current(explode(",", $A))
will both return the value 123132
You can do
$A='123132,32132,123132321321,3';
$t=explode(',',$A);
$result = $t[0];

PHP preg_split string into letter pairs
I have an string looking like this:
$str = "How are you doing?";
How can I turn this string into an array looking like this:
$arr = array("Ho","w ","ar","r ","yo","u ","do","in","g?");
$array = str_split($str, 2);
Documentation.
Use str_split() function.
Take a look at str_split(); it allows you to split a string by a definable amount of characters, so your code would look like:
$arr = str_split($str, 2);
Which will split $str into an array $arr where each element contains two characters,
