sum items stor in array - arrays

I have this code:
$str='ياسمين';
$a=utf8Split(trim($str));
for($i=0;$i<=strlen($a);$i++)
{
$sql_char=("SELECT num FROM alphabet where letters = '$a[$i]'");
$result = mysql_query ($sql_char,$dbConn);
while($row = mysql_fetch_array($result))
echo $row['num'].'<br>';
}


Try simply to add your $row['num'] to a new variable
$sum=0;
while($row = mysql_fetch_array($result)){
echo $row['num'].'<br>';
$sum=$sum+$row['num'];
}
echo $sum; //171
EDIT
function mb_str_split( $string ) {
# Split at all position not after the start: ^
# and not before the end: $
return preg_split('/(?<!^)(?!$)/u', $string );
}
$str = 'ياسمين';
$charlist = mb_str_split( $str );
print_r( $charlist );

Undefined array key 1 in foreach loop

i have this piece of code. On the top i download text data from URL and i get string. This string has some uninportant text so this text is in $info and important number are in $array than i did some reIndex array because for some reason i had $array[0] empty.
I have 2 array: $array and $array_try both arrays shoud have similar structure as u can see here:
For some reason im getting Undefined array key 1 in this line $array_value[] = $parts[1];
When i change in foreach loop $array for $array_try it works well.
Best
$data = file_get_contents("$url");
$data = explode('Kurz', $data);
$kurz = '|Kurz';
$info= substr_replace($data[0], $kurz, -1, );
echo "<br>";
$array = explode ("\n", $data[1]);
//foreach ($array as $value){
// echo $value . "<br>";
//}
unset($array[0]);
$array = array_values($array);
$array_try = [
"04.01.2021|26,140",
"05.01.2021|26,225",
"06.01.2021|26,145"
];
$array_date = [];
$array_value = [];
foreach($array as $value) {
$parts = explode('|', $value);
$array_date[] = $parts[0];
$array_value[] = $parts[1];
}
var_dump($array_try);
echo "<br>";
echo "<br>";
var_dump($array);

filter file by unique and biggest value; combine two arrays into hash

I need to extract by unique genus (first part of the name of species) in one column but with by biggest number in another column in a CSV file when having multiples of the same name.
So if have multiple genus (same first name) then take the biggest number in the last column to select which will represent that genus.
I have extracted the information into arrays, but I am having trouble with combining the two in order to select. I was using
https://perlmaven.com/unique-values-in-an-array-in-perl
to help but I need to include biggest number in last column when have the same genus situation.
use strict;
use warnings;
open taxa_fh, '<', "$ARGV[0]" or die qq{Failed to open "$ARGV[0]" for input: $!\n};
open match_fh, ">$ARGV[0]_genusLongestLEN.csv" or die qq{Failed to open for output: $!\n};my #unique;
my %seen;
my %hash;
while ( my $line = <taxa_fh> ) {
chomp( $line );
my #parts = split( /,/, $line );
my #name = split( / /, $parts[3]);
my #A = $name[0];
my #B = $parts[5];
#seen{#A} = ();
my #merged = (#A, grep{!exists $seen{$_}} #B);
my #merged = (#A, #B);
#hash{#A} = #B;
print "$line\n";
}
close taxa_fh;
close match_fh;

Properly naming the variables makes the code more readable:

$selected{$genus}{max} = $value;
$selected{$genus}{line} = $_;
}
}
for my $genus (keys %selected) {
print $selected{$genus}{line};
}
The order of the output lines is random.

You can this Perl command line as well
perl -F, -lane ' ($g=$F[3])=~s/(^\S+).*/$1/; if( $mx{$g}<$F[-1])
{ $kv{$g}=$_;$mx{$g}=$F[-1] } END { print $kv{$_} for(keys %kv) } ' file
with the given inputs in cara.txt file, the output is
$ perl -F, -lane ' ($g=$F[3])=~s/(^\S+).*/$1/; if( $mx{$g}<$F[-1])

Don't see an obvious method that you are sorting your output by

array of ints remains undef after multiple push() calls

I'm trying to save error codes by:
#global space
my #retCodes;

print "\n------>> Waiting for prior actions to finish up... <<------\n";
}

$q->end();
$_->join() for threads->list();
return 0;
}

my $tries = 1;

}
Error that gets displayed:
Use of uninitialized value $maxReturnCode in concatenation (.) or
string at C:\script.pl line 66, line 415.
I can see from the first line of output though, that I get things like: Return Code: 0 Return Code: 0 Return Code: 2 ..

The issue here is that the code isn't sharing the array between threads; so because of that, each thread is modifying it's local copy of the array, not the global array as expected. The fix for this problem is to share the variable, and lock it before accessing it during the thread processing:
my #retCodes;
share(#retCodes);
...
#during the thread sub
lock(#retCodes);
push(#retCodes, ($retCode>>8));

Here's a stubbed-out runnable version that you should be able to modify a bit to do what you need:
#!/usr/bin/perl
use strict;
use warnings;
use List::Util 'max';
use threads;
#global space
my #retCodes = ();
share(#retCodes);
sub builder {
my ($comp, $cmd) = ('builder', 'test');
for my $retCode (qw/0 0 256/) {
print "\n\t\tReturn Code: " . ($retCode >>8) . "\n";
lock(#retCodes);
push(#retCodes, ($retCode>>8));
}
}
#main
builder();
# other threads started...
# wait for threads to complete...
printf "Codes: %s\n", join(', ', #retCodes);
my $maxReturnCode = max(#retCodes);
print "Highest Error Code: $maxReturnCode\n"; #<-- crashes with error below
exit($maxReturnCode);

unable to itherate through the array perl

I have this perl script:
my %perMpPerMercHash;
foreach my $sheet () { #proper ranges specified
foreach my $row ( ) { #proper ranges specified
#required variables declared.
push(#{$perMpPerMercHash{join("-", $mercId, $mpId)}}, $mSku);
}
}
#Finally 'perMpPerMercHash' will be a hash of array`
foreach my $perMpPerMerc ( keys %perMpPerMercHash ) {
&genFile($perMpPerMerc, $perMpPerMercHash{$perMpPerMerc});
}
sub genFile {
my ( $outFileName, #skuArr ) = #_;
my $output = new IO::File(">$outFileName");
my $writer = new XML::Writer( OUTPUT => $output, DATA_MODE => 1, DATA_INDENT => 2);
#mpId is generated.
&prepareMessage($writer, $mpId, #skuArr);
}
sub prepareMessage {
my ( $writer, $mpId, #skuArr ) = #_;
my $count = 1;
print Dumper \#skuArr; #Printing correctly, 8-10 values.
foreach my $sku ( #skuArr ) { #not iterating.
print "loop run" , $sku, "\n"; #printed only once.
}
}
Can somebody please help why this is happening. I am new to perl and could not understand this anomaly.
EDIT:
output of Dumper:
$VAR1 = [
'A',
'B',
'C',
];

When you do
&genFile($perMpPerMerc, $perMpPerMercHash{$perMpPerMerc});
You're passing a reference to an array.
So in
sub genFile {
my ( $outFileName, #skuArr ) = #_;
You have to do :
sub genFile {
my ( $outFileName, $skuArr ) = #_;
and then use #$skuArr.
Have a look at references
The modified genFile sub will be:
sub genFile {
my ( $outFileName, $skuArr ) = #_;
my $output = new IO::File(">$outFileName");
my $writer = new XML::Writer( OUTPUT => $output, DATA_MODE => 1, DATA_INDENT => 2);
#mpId is generated.
&prepareMessage($writer, $mpId, #$skuArr);
}
And the other sub don't need to be modified.
Or you can pass always skuArr by reference:
&genFile($perMpPerMerc, $perMpPerMercHash{$perMpPerMerc});
...
sub genFile {
my ( $outFileName, $skuArr ) = #_;
...
&prepareMessage($writer, $mpId, $skuArr);
}
sub prepareMessage {
my ( $writer, $mpId, $skuArr ) = #_;
my $count = 1;
print Dumper $skuArr;
foreach my $sku ( #$skuArr ) {
print "loop run" , $sku, "\n";
}
}

Undefined offset: 1 twitch channel grab

I get this on my website:

Any hints?
