Question

this is probably a ridiculous question to ask but i am learning php so please help if you can.

I have a file called ‘res_example.txt’ and it looks like this:

>chr1:2198584545754_genome_1000+ 511 66 (+) nan full_model
>chr2:2198581212154_genome_1000+ 649 70 (+) nan full_model
>chr3:2115151215754_genome_1000+ 666 80 (+) nan full_model
>chr4:2198584545754_genome_1000+ 750 90 (+) nan full_model
>chr5:1218455145754_genome_1000+ 800 100 (+) nan full_model
>chr6:1231354645454_genome_1000+ 850 110 (+) nan full_model
>chr7:1231213211134_genome_1000+ 900 120 (+) nan full_model

I want to open this file. Put each line into an array $resArray, so each line is a separate string.
so it will be like this:

$resArray= array(' >chr1:2198584545754_genome_1000+ 511 66 (+) nan full_model',  '>chr2:2198581212154_genome_1000+ 649 70 (+) nan full_model')

etc

Then with Each key from $resArray, I want to create another Array $ArrayResults exploding each string at each space in the string. This will ow me to work with each part of each string separately.

I hope this ,made sense. I probably didn’t ask the question in the right way, so Apologies.

Thanks for any help.

I want to open this file. Put each line into an array

file()

with Each key from $resArray, I want to create another Array $ArrayResults exploding each string at each space in the string

explode()

So it’ll become something like this:

$resArray = file('res_example.txt');
$resSplit = array();

foreach ($resArray as $res)
{
    $resSplit[] = explode(' ', $res);
}
