Input string:
:txt{sometext}:alpha
I want to extract data like this (extracted from brackets):
Result using preg_match_all():
sometext
Trying like this, but none of this works:
php > preg_match_all('/^(\:txt)(.*)+(\{)(.*)+(\})/i', ':txt{sometext}:alpha', $m); var_dump($m);
array(6) {
[0] =>
array(1) {
[0] =>
string(14) ":txt{sometext}"
}
[1] =>
array(1) {
[0] =>
string(1) ":"
}
[2] =>
array(1) {
[0] =>
string(0) ""
}
[3] =>
array(1) {
[0] =>
string(1) "{"
}
[4] =>
array(1) {
[0] =>
string(0) ""
}
[5] =>
array(1) {
[0] =>
string(1) "}"
}
}
Note: as sample I have like this :txt{sometext}:alpha:another{mydata}, so I can extract data from :another and give results like mydata.
RESULTS:
Result from Sniffer:
php > preg_match_all('/(?<=:txt{)([^}]+)(?=})/', ':txt{sometext}:alpha', $x); var_dump($x);
array(2) {
[0] =>
array(1) {
[0] =>
string(8) "sometext"
}
[1] =>
array(1) {
[0] =>
string(8) "sometext"
}
}
Result from Jerry:
php > preg_match_all('/^:txt\{([^}]+)\}/', ':txt{sometext}:alpha', $x); var_dump($x);
array(2) {
[0] =>
array(1) {
[0] =>
string(14) ":txt{sometext}"
}
[1] =>
array(1) {
[0] =>
string(8) "sometext"
}
}
Why all this, why not just:
(?<=:txt{)([^}]+)(?=})

I'm recieving the following multidimensional array via an ajax post:
array(1) {
["result"] => array(3) {
[0] => array(2) {
[0] => string(1)
"0" [1] => array(2) {
["id"] => string(5)
"1§10" ["children"] => array(2) {
[0] => array(1) {
["id"] => string(6)
"1§3$0"
} [1] => array(1) {
["id"] => string(6)
"1§1$0"
}
}
}
} [1] => array(2) {
[0] => string(1)
"1" [1] => array(1) {
["id"] => string(5)
"3§20"
}
} [2] => array(2) {
[0] => string(1)
"2" [1] => array(2) {
["id"] => string(5)
"2§30" ["children"] => array(1) {
[0] => array(1) {
["id"] => string(6)
"2§2$0"
}
}
}
}
}
}
Is there a way to return only the strings one by one with php? The depth of the of the string in the array does not matter what so ever since i will only parse and explode the id strings.
You can implement simple recorsice function as:
function printString($arg) {
if (is_string($arg))
echo $arg . PHP_EOL;
else (is_array($arg)) {
foreach($arg as $e)
printString($e);
}
}
Or use array_walk_recursive as:
function printStr($item, $key) {
echo $item . PHP_EOL;
}
array_walk_recursive($arr, 'printStr');
If you only need the "id" string do:
function printId($item, $key) { if ($key == "id") echo $item . PHP_EOL; }
array_walk_recursive($arr, 'printId');

Having the following array:
array(4) {
[0]=>
array(2) {
[0]=>
string(3) "233"
[1]=>
string(37) "some data"
}
[1]=>
array(2) {
[0]=>
string(3) "233"
[1]=>
string(68) "some other data"
}
[2]=>
array(2) {
[0]=>
string(3) "144"
[1]=>
string(38) "some other data"
}
[3]=>
array(2) {
[0]=>
string(3) "233"
[1]=>
string(42) "some other data"
}
}
I want to replace the values 233 and 144 (the key 0 from the inner array) by some random HEX color. The ones with the same keys (233) for example, has to have the same HEX color (FFF000 for example in the desired solution above).
This is the function I use to generate random HEX colors:
function randHEXcolor() {
return sprintf('%06X', mt_rand(0, 0xFFFFFF));
}
My desired output should be:
array(4) {
[0]=>
array(2) {
[0]=>
string(6) "FFF000"
[1]=>
string(37) "some data"
}
[1]=>
array(2) {
[0]=>
string(6) "FFF000"
[1]=>
string(68) "some other data"
}
[2]=>
array(2) {
[0]=>
string(6) "111333"
[1]=>
string(38) "some other data"
}
[3]=>
array(2) {
[0]=>
string(6) "FFF000"
[1]=>
string(42) "some other data"
}
}
How can I archieve this?
Thanks in advance.
foreach ($array as &$item) {
if (!isset($temp[$item[0]]) {
$temp[$item[0]] = randHEXcolor();
}
$item[0] = $temp[$item[0]];
}
If you want all values to be translated to the same random color, you'll have to save those colors:
$colors_translation = array();
foreach ($array as &$item) {
$color = $item[ 0 ];
$translate = $colors_translation[ $color ];
if (empty($translate)) {
$colors_translations[ $color ] = $translate = randHEXcolor();
}
$item[ 0 ] = $translate;
}
The solution using in_array and isset functions:
$keys = [];
foreach ($arr as &$v) { // $arr is your initial array
if (in_array($v[0], ['233', '144'])) {
if (!isset($keys[$v[0]])) $keys[$v[0]] = sprintf('%06X', mt_rand(0, 0xFFFFFF));
$v[0] = $keys[$v[0]];
}
}
print_r($arr);
The output:
Array
(
[0] => Array
(
[0] => 65A4BB
[1] => some data
)
[1] => Array
(
[0] => 65A4BB
[1] => some data
)
[2] => Array
(
[0] => DDB588
[1] => some data
)
[3] => Array
(
[0] => 65A4BB
[1] => some data
)
)
This code will create a color map as the array is traversed. Pre-populate $colorMap if you want pre-defined color translations.
<?php
$array = array(
0 => array(
0 => "233",
1 => "some data"
),
1 => array(
0 => "233",
1 => "some data"
),
2 => array(
0 => "144",
1 => "some data"
),
3 => array(
0 => "233",
1 => "some data"
),
);
$colorMap = array();
foreach ($array as &$inner) {
if (!array_key_exists($inner[0],$colorMap)) {
$newColor = randHEXcolor();
$colorMap[$inner[0]] = $newColor;
$inner[0] = $newColor;
} else {
$inner[0] = $colorMap[$inner[0]];
}
}
function randHEXcolor() {
return sprintf('%06X', mt_rand(0, 0xFFFFFF));
}
print_r($array);
print_r($colorMap);
Array
(
[0] => Array
(
[0] => F1519A
[1] => some data
)
[1] => Array
(
[0] => F1519A
[1] => some data
)
[2] => Array
(
[0] => 2F7D00
[1] => some data
)
[3] => Array
(
[0] => F1519A
[1] => some data
)
)
Array
(
[233] => F1519A
[144] => 2F7D00
)
Try:
<?php
$array = array(
0 => array(
0 => "233",
1 => "some data"
),
1 => array(
0 => "233",
1 => "some data"
),
2 => array(
0 => "144",
1 => "some data"
),
3 => array(
0 => "233",
1 => "some data"
),
);
function randHEXcolor() {
return sprintf('%06X', mt_rand(0, 0xFFFFFF));
}
$firstHex = randHEXcolor();
$secondHex = randHEXcolor();
foreach($array as $arrayIndex => &$arrayValue){
if($arrayValue[0] == "144"){
$arrayValue[0] = $firstHex;
}
if($arrayValue[0] == "233"){
$arrayValue[0] = $secondHex;
}
}
output:

[0]=>
array(2) {
[0]=>
string(6) "AB8248"
[1]=>
string(9) "some data"
}
[1]=>

I am using the results from a db query to populate an array. If I do a var_dump on the array, it looks fine. However, if I try to access the elements of the array by echoing $myArray[0] or any other element in the array, all I get is array.
Here is an excerpt of my code.
$losers = array();
if ($result=mysqli_store_result($con))
{
while ($row=mysqli_fetch_row($result))
{
//printf("%s\n",$row['Winner']);
if($row[0]!= "MLB"){
$data[] = $row;
echo $row[0] . '<br />';
Where I am using the echo for the row element, no problems, it does fine. Here are the results of my var_dump
array(4) { [0] => array(4) { [0] => string(3) "MLB" [1] => string(15) "Cincinnati Reds" [2] => string(4) "-137" [3] => string(88) "images/mlb/cred.jpg" } [1] => array(4) { [0] => string(3) "MLB" [1] => string(15) "Minnesota Twins" [2] => string(4) "-128" [3] => string(88) "images/mlb/mtwi.jpg" } [2] => array(4) { [0] => string(3) "MLB" [1] => string(14) "Atlanta Braves" [2] => string(4) "-101" [3] => string(88) "images/mlb/Abra.jpg" } [3] => array(4) { [0] => string(3) "MLB" [1] => string(20) "Washington Nationals" [2] => string(4) "-140" [3] => string(88) "images/mlb/wnat.jpg" } }
And this is what happens when I use echo to show the results of the array.
ArrayArrayArrayArrayArrayArrayArrayArrayArrayArray
That is obviously because element 0 is actually an array. When you try to echo an array, not surprisingly, you get Array and a warning. To print an array use print_r($array, true);
$losers = array();
if ($result=mysqli_store_result($con))
{
while ($row=mysqli_fetch_row($result))
{
//printf("%s\n",$row['Winner']);
if($row[0]!= "MLB"){
$data[] = $row;
echo print_r($row[0], true) . '<br />';
I have had success merging two arrays by difference using the following code:
$a=array("2013-08-22"=>"12","2013-08-25"=>"5","2013-08-27"=>"10");
$b=array("2013-08-22"=>"1","2013-08-23"=>"3","2013-08-25"=>"5","2013-08-27"=>"10","2013-08-29"=>"5");
foreach ($b as $key => $value){
if(!array_key_exists($key, $a)){
$a[$key]=0;
}
}
This will return:
Array
(
[2013-08-22] => 0
[2013-08-23] => 0
[2013-08-25] => 5
[2013-08-27] => 10
[2013-08-29] => 0
[2013-12-22] => 12
)
The idea is for a to additionally hold the elements from b that are not present in a.
I am having issues now doing the same thing for the following array format:
$a=array(array("2013-12-22","12"),array("2013-08-25","5"),array("2013-08-27","10"));
$b=array(array("2013-08-22","1"),array("2013-08-23","3"),array("2013-08-25","5"),array("2013-08-27","10"),array("2013-08-29","5"));
I went to try this:
foreach ($b as $key => $value){
if(!array_key_exists($key, $a)){
$a[$key]=array($value[0], 0);
}
}
But the returned result is far from what I need:
Array
(
[0] => Array
(
[0] => 2013-12-22
[1] => 12
)
[1] => Array
(
[0] => 2013-08-25
[1] => 5
)
[2] => Array
(
[0] => 2013-08-27
[1] => 10
)
[3] => Array
(
[0] => 2013-08-27
[1] => 0
)
[4] => Array
(
[0] => 2013-08-29
[1] => 0
)
)
I understand they keys are no longer the dates, but how should I go about checking each array and making sure I don't get double entries?
$a = array(
array("2013-12-22","12"),
array("2013-08-25","5"),
array("2013-08-27","10"));
$b = array(
array("2013-08-22","1"),
array("2013-08-23","3"),
array("2013-08-25","5"),
array("2013-08-27","10"),
array("2013-08-29","5"));
$exists = array();
foreach ($a as $data) {
$exists[$data[0]] = 1;
}
foreach ($b as $data) {
if (array_key_exists($data[0], $exists)) {
continue;
}
$a[] = array($data[0], $data[1]);
}
$a now contains:
array(6) {
[0]=>
array(2) {
[0]=>
string(10) "2013-12-22"
[1]=>
string(2) "12"
}
[1]=>
array(2) {
[0]=>
string(10) "2013-08-25"
[1]=>
string(1) "5"
}
[2]=>
array(2) {
[0]=>
string(10) "2013-08-27"
[1]=>
string(2) "10"
}
[3]=>
array(2) {
[0]=>
string(10) "2013-08-22"
[1]=>
string(1) "1"
}
[4]=>
array(2) {
[0]=>
string(10) "2013-08-23"
[1]=>
string(1) "3"
}
[5]=>
array(2) {
[0]=>
string(10) "2013-08-29"
[1]=>
string(1) "5"
}
}
i have a string like this one:
$string = "some text

http://192.168.3.192/roadmap_page.php#qwe";
need to get all links.
i tried this way: /http:\/\/(.*)[|\s]?/
returns:
array(2) {
[0] =>
array(3) {
[0] =>
string(42) "http://dvz.local/index/index/regionId/28\r\n"
[1] =>

expect:

}
}
Try this one:
/http:\/\/([^\s]+)/
Try this:
preg_match_all('|http://([^\s]*)|', $string, $matches);
var_dump($matches);
All links from text
http[s]?[^\s]*
Numerous pages have only relative links to the main document, (thus no http(s):// ... to parse), for those the following works fine, splitting by the href attribute:
preg_match_all('|href="([^\s]*)"><\/a>|', $html, $output_array);
Or even simpler:
preg_match_all('|href="(.*?)"><\/a>|', $html, $output_array);
Example output:
[0]=>
string(56) "/broadcast/bla/xZr300"
[1]=>
string(50) "/broadcast/lol/fMoott"
