for($i = 0 ; $i < $first_loop_len ; $i++){
    $star_1 = "*" ;
    echo $star_1; ;

}

for($i = 0 ; $i < $first_loop_len ; $i++){
    $star_1 = "*" ;
    echo $star_1; ;

}

why when i put echo in loop it will show 8 start and when i put echo outside loop it show only 1 star in javascript for fix the issue i do $star_1 += "*" ; but in php i cant is there any way i get like 8 start every time i call it ? not only 1

because you can't increment an asterisk by an asterisk

hmm

ἔρως•16mo ago

you probably want to do $star .= '*'

NIMAOP•16mo ago

$star += '*'

but what you REALLY want is str_repeat('*', 8)

this doesn't work because it is the same as $star = (int)$star + (int)'*' which makes no sense https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/repeat <-- '*'.repeat(8)

you're welcome in php, you want to do $star .= '*', by the way

the . is used to concatenate strings, meaning that it is the same as this: $star = $star . '*'
