i have string like this
$string = '$foo$wow$123$$$ok$';
i want to return empty string and save string in array like this
0 = foo
1 = wow
2 = 123
3 =
4 =
5 = ok
i use PREG_SPLIT_NO_EMPTY, i know when make PREG_SPLIT_NO_EMPTY return is not empty, but i want any result empty, i want my result save in variable array like in PREG_SPLIT_NO_EMPTY with $chars[$i];
this is my preg_split :
$chars = preg_split('/[\s]*[$][\s]*/', $string, -1, PREG_SPLIT_NO_EMPTY);
for($i=0;$i<=5;$i++){
echo $i.' = '.$chars[$i];
}
i want, my result show with looping. no in object loop i want pure this looping:
for($i=0;$i<=5;$i++){
echo $i.' = '.$chars[$i];
}
to show my result.
how i use this preg_split,
thanks for advance...
use explode
$str = '$foo$wow$123$$$ok$';
$res = explode ("$",$str);
print_r($res);
Array
(
[0] =>
[1] => foo
[2] => wow
[3] => 123
[4] =>
[5] =>
[6] => ok
[7] =>
)
Using explode adds the empty entrys to the front and the back.
This one matches the tc's expected output:
$str = '$foo$wow$123$$$ok$';
preg_match_all("#(?<=\\$)[^\$]*(?=\\$)#", $str, $res);
echo "<pre>";
print_r($res);
echo "</pre>";
[0] => Array
(
[0] => foo
[1] => wow
[2] => 123
[3] =>
[4] =>
[5] => ok
)

Does anyone know how I can create an Array?
$string = '3-1-0-1.11,3-1-1-1.12,3-1-2-1.13,3-1-3-1.14,3-2-0-1.02,3-2-1-1.03,3-2-2-1.04,3-2-3-1.05,3-2-4-1.06,3-3-0-3.23,3-3-1-3.24,3-3-2-3.25,3-3-3-3.26';
$array = explode(',', $string);
$last_entry = null;
foreach ($array as $current_entry) {
$first_char = $current_entry[2]; // first Sign
if ($first_char != $last_entry) {
echo '<h2>'. $first_char . '</h2><br>';
}
echo $current_entry[4] . '<br>';
$last_entry = $first_char;
}
I need an Array like this:
Array
(
[1] => Array
(
[0] => 0
[1] => 1
[2] => 2
)
[2] => Array
(
[0] => 0
[1] => 1
[2] => 2
[3] => 3
[4] => 4
[5] => 5
)
[3] => Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
)
)
The first number 3 and other numbers 3 after comma are not important.
Important numbers are second and third numbers in values of $array.
I need categories. Example: if the first (second) number is 1 create Category 1 and subcategory 1 where first (second) number actual is 1.
To create an an array, you need to declare it using array() feature. Below I have created a blank array.
$array = array();
An array with values looks like this
$array = array("string", "string2", "string3");
To add values in an array, you use the array_push method.
array_push($array, "string4");
On multidimensional arrays, declare the array then add the inner array, below is objct oriented
$array = array("string"=>array("innerstring", "innerstring2"), "string2" => array("innerstring3", "innerstring4"), "string3" => array("innerstring5", "innerstring6"));
and procedural
$array=array(array("string", "innerstring", "innerstring2",), array("string2", "innerstring3", "innerstring4"), array("string3", "innerstring5", "innerstring6"));
Try next script:
$string = '3-1-0-1.11,3-1-1-1.12,3-1-2-1.13,3-1-3-1.14,3-2-0-1.02,3-2-1-1.03,3-2-2-1.04,3-2-3-1.05,3-2-4-1.06,3-3-0-3.23,3-3-1-3.24,3-3-2-3.25,3-3-3-3.26';
foreach(explode(',', $string) as $tpl) {
$tpl = explode('-', $tpl);
$tpl[3] = explode('.', $tpl[3]);
$result[$tpl[1]][$tpl[2]][$tpl[3][0]] = !empty($tpl[3][1]) ? $tpl[3][1] : null;
}
var_dump($result);
I'm having trouble converting a string to a multi-dimensional array in php. This is my string:
$String = a,b,c|d,e,f|g,h,y|
This is what I'm trying:
$one=explode("|",$String);
foreach ($one as $item)
{
$one=explode(",",$one);
}
I'd like to create this array:
$array={ {a,b,c}, {d,e,f}, {g,h,y} };
Try with -
$one=explode("|",$String);
$array = array();
foreach ($one as $item){
$array[] = explode(",",$item);
}
Try this code:
$string = 'a,b,c|d,e,f|g,h,y|';
$arr = array_map(function($iter){ return explode(',',$iter);},explode('|',$string));
Hope it help a bit.
You have almost done it right, except for the cycle part. Try this
$result = [];
$String = 'a,b,c|d,e,f|g,h,y|';
$firstDimension = explode('|', $String); // Divide by | symbol
foreach($firstDimension as $temp) {
// Take each result of division and explode it by , symbol and save to result
$result[] = explode(',', $temp);
}
print_r($result);
Try this-
$String = 'a,b,c|d,e,f|g,h,y|';
$one = array_filter(explode("|", $String));
print_r($one); //Array ( [0] => a,b,c [1] => d,e,f [2] => g,h,y )
$result = array_map('v', $one);
function v($one) {
return explode(',',$one);
}
print_r($result); // Array ( [0] => Array ( [0] => a [1] => b [2] => c ) [1] => Array ( [0] => d [1] => e [2] => f ) [2] => Array ( [0] => g [1] => h [2] => y ) )
Use this code
$String= 'a,b,c|d,e,f|g,h,y|';
$one=explode("|",$String);
print_r(array_filter($one));
Output will be
Array
(
[0] => a,b,c
[1] => d,e,f
[2] => g,h,y
)
I have an array which looks like this:
Array
(
[0] => Array
(
[0] => TE=140414100000 cd =AB1234 ggg =1234567 gbh =2
[7] => nd: DA1AAAAAAAAAA: TD = 140414:
)
[1] => Array
(
[0] => TE=140414100000 cd =AB1234 ggg =1234567 ghb =2
[7] => nd: DA1AAAAAAAAAA: TD = 140414:
)
)
what I am trying to acomplish is to parse data within each sub array and create a new multidimensional array with the parsed data.
Example: the data in parentheses below is what should be returned in new multidimensional array
Array
(
[0] => Array
(
[0] => te=(140414100000) cd =AB(1234) ggg =1234567 ghb =2
[7] => nd: DA(1)(AAAAAAAAAA): TD = (140414):
)
[1] => Array
(
[0] => te=(140414100000) cd =AB(1234) ggg =1234567 ghb =2
[7] => nd: DA(2)(BBBBBBBBBB): TD = (140414):
)
)
What I want to return:
Array
(
[0] => Array
(
[0] => 140414100000
[1] => 1234
[2] => 1
[3] => AAAAAAAAAA
[4] => 140414
)
[1] => Array
(
[0] => 140414100000
[1] => 1234
[2] => 2
[3] => BBBBBBBBBB
[4] => 140414
)
).
So my question is what would be the best way to acomplish this?
This is what I have come up with. It works, however is seems very inefficient as it adds a lot of empty arrays which have to be cleaned up.
foreach($new as $key => $val){
foreach($val as $res){
preg_match_all('%te=([0-9]{12})\s%',$res,$matches);
$out[$key][] = $matches[1][0];
preg_match_all('%cd\s+=AB([0-9]{4})%',$res,$matches);
$out[$key][] = $matches[1][0];
preg_match_all('%nd:\sDA([0-9]{1})%',$res,$matches);
$out[$key]['node'] = $matches[1][0];
preg_match_all('%nd:\sDA[0-9]{1}([a-zA-Z]{10,14}):%',$res,$matches);
$out[$key]['rset'] = $matches[1][0];
preg_match_all('%td\s=\s([0-9]{6}):%',$res,$matches);
$out[$key]['trdt'] = $matches[1][0];
}
}
foreach($out as $v){
$v = array_values(array_filter($v));
$return[] = $v;
}
return $return;
Thanks in advance.
UPDATED:
This worked and is much more efficient. Thanks for the example Shankar
foreach($new as $key => $val){
$v = implode('', $val);
preg_match_all("%te=([0-9]{12})|cd\s+=AB([0-9]{4})|nd:\sDA([0-9]{1})|([A-Z]{3,7}):|td=\s([0-9]{6}):%",$v,$matches);
$new_array[$key]['time'] = $matches[1][0];
$new_array[$key]['code'] = $matches[2][1];
$new_array[$key]['sp'] = $matches[3][2];
$new_array[$key]['rset'] = $matches[4][3];
$new_array[$key]['trfdt'] = $matches[5][4];
}
echo "<pre>";
print_r($new_array);
echo "</pre>";
Loop through your array and implode each array element and use a preg_match_all() to capture all the entries bewteen ( and ) and then pass those matches to your new array.
foreach($arr as $k=>$arr1)
{
$v = implode('',$arr1);
preg_match_all('^\((.*?)\)^', $v, $matches);
$new_arr[]=$matches[1];
}
print_r($new_arr);
Working Demo
i have strings that looks similar like this:
"size:34,35,36,36,37|color:blue,red,white"
is it possible to match all the colors in a preg_match(_all)?
so that i will get "blue", "red" and "white" in the output array?
the colors can be whatever, so i cant go (blue|red|white)
Explode on |
Explode on :
Explode on ,
???
Profit!
Code
IMHO using regular expressions like what's been suggested in the other answers is a much "uglier" solution than something simple like so:
$input = 'size:34,35,36,36,37|color:blue,red,white|undercoating:yes,no,maybe,42';
function get_option($name, $string) {
$raw_opts = explode('|', $string);
$pattern = sprintf('/^%s:/', $name);
foreach( $raw_opts as $opt_str ) {
if( preg_match($pattern, $opt_str) ) {
$temp = explode(':', $opt_str);
return $opts = explode(',', $temp[1]);
}
}
return false; //no match
}
function get_all_options($string) {
$options = array();
$raw_opts = explode('|', $string);
foreach( $raw_opts as $opt_str ) {
$temp = explode(':', $opt_str);
$options[$temp[0]] = explode(',', $temp[1]);
}
return $options;
}
print_r(get_option('undercoating', $input));
print_r(get_all_options($input));
Output:
Array
(
[0] => yes
[1] => no
[2] => maybe
[3] => 42
)
Array
(
[size] => Array
(
[0] => 34
[1] => 35
[2] => 36
[3] => 36
[4] => 37
)
[color] => Array
(
[0] => blue
[1] => red
[2] => white
)
[undercoating] => Array
(
[0] => yes
[1] => no
[2] => maybe
[3] => 42
)
)
You can achieve it in a round about way with preg_match_all() but I'd recommend explode instead.
preg_match_all('/([a-z]+)(?:,|$)/', "size:34,35,36,36,37|color:blue,red,white", $a);
print_r($a[1]);
I think it's possible with lookbehind:
/(?<=(^|\|)color:([^,|],)*)[^,|](?=\||,|$)/g
(for preg_match_all)
Your explode solution is obviously cleaner :-)
foreach($files as $file) {
$xname = basename($file['name'],'.jpg');
$tmp = preg_split("/[\s,-]+/",$xname,-1, PREG_SPLIT_NO_EMPTY);
echo "<pre>";
print_r($tmp);
echo "</pre>";
here is the example string "LR-147-TKW FLOWER RECT MIRROR FRAME"
I have this line of code that splits my string to arrays. What i want it do is to get the first 3 words which is "LR-147-TKW" and store it to a variable. how can i achieve this?
my array output is this 0] => BR
[1] => 139
[2] => TKW
[3] => DRESSER
[4] => BUFFET
[5] => MIRROR
You can use explode(), here are some examples:
<?php
$str = 'LR-147-TKW FLOWER RECT MIRROR FRAME';
$parts = explode(' ',$str);
print_r($parts);
/*
Array
(
[0] => LR-147-TKW
[1] => FLOWER
[2] => RECT
[3] => MIRROR
[4] => FRAME
)
*/
$serial_parts = explode('-',$parts[0]);
print_r($serial_parts);
/*
Array
(
[0] => LR
[1] => 147
[2] => TKW
)
*/
$full = array_merge($serial_parts,$parts);
print_r($full);
/*
Array
(
[0] => LR
[1] => 147
[2] => TKW
[3] => LR-147-TKW
[4] => FLOWER
[5] => RECT
[6] => MIRROR
[7] => FRAME
)
*/
?>
this actually does the trick for you current input. $tmp will contain LR-147-TKW after you execute this line of code:
list($tmp) = explode(' ', $input);
This is because preg_split("/[\s,-]+/",... splits your string where ever a comma, minus or space occurs. Change it to preg_split("/[\s,]+/",...) and it should give you the correct array.
Note that if you do that, your function won't split words like WELL-SPOKEN. It will become one entry in your array.
Considering your string has same pattern.
$str = "LR-147-TKW FLOWER RECT MIRROR FRAME";
$str1 = explode(' ',$str);
echo $str1[0];
How about using explode :
$arr = explode(' ',$file);
echo arr[0];
using preg_split is a bit of overkill for such a simple task...
If you want to avoid the array, it can be done using strpos and substr:
$pos = strpos($file, ' ');
echo substr('abcdef', 0, $pos);
add to your code:
$tmp = array_slice($tmp,0,3);
