php - Getting values to compare from a Explode Array of Strings
Get the solution ↓↓↓
I have this string that I'm Getting from a Mysql Result:
Result1:
1/test3&2/test4&
Then, I have some ID from another mysql Result like this:
Result2:
$id = $row['id'];
Then I'm using an Explode in order to separate Result1:. Like I'm Getting this:
$nota3 = explode("&", $nota);
1/test3&
2/test4&
Now, I'm doing I'm using a foreach and then using another explode to separate the string by "/" delimiter.
foreach ($nota3 as $key) {
$nota4 = explode("/", $key);
}
The Result of this its something like this (for the firsts foreach iteration):
array(2) {
[0]=>
string(1) "1"
[1]=>
string(5) "test3"
}
Ok, So I cannot Comparenota4[0] with$id from Result2:
Things that I've Tried:
Using if and verify every type, converts
nota4[0]a$idto stringTry to use in_Array
Try to use strcmp($var1, $var2)
I'm Missing something but I really dont know what.
Also, when I tried I cant putnota4[0] into a html String like
$nota5= nota4[0];
echo "<p id='mic' class='text-dark bg-warning'>".$nota5."</p>";
Maybe its something silly but I tried everything without success.

Solution:
You can make sure both are strings and trim and use a strict operator - even if it seems they are already that
$result1 = "1/test3&2/test4&";
$result2 = "1";
$id = trim((string) $result2);
foreach ($nota3 as $key) {
$nota4 = explode("/", $key);
if (trim((string) $nota4[0]) === $id) {
//...
}
}
Here's another way to go about it. This will set up $result1 (or you can rename it) to become an associative array of key/value pairs, allowing you to loop through and compare a value like$result2 with a keyid in the$result1 array. Example link included.
<?php
$result1 = "1/test3&2/test4&";
$result2 = "1";
$result1 = array_map(function ($a) {
$tmp = explode("/", $a);
return array('id' => $tmp[0],'name' => $tmp[1]);
}, array_filter(explode("&", $result1)));
print_r($result1);
now to get $result2
foreach ($result1 as $item) {
if ($item['id'] == $result2) {
// $value
}
}
Output of result1
[0] => Array
(
[id] => 1
[name] => test3
)
[1] => Array
(
[id] => 2
[name] => test4
)
