如何将字符串转换为变量并仍然获得良好的输出

Question

How do i turn an string into variables and still get a good output.

$text = "showandreturn";

$disp = str_split($text, 2); 

$firstnum = 3;

for($b = 0; $b<$firstnum; $b++){

    $a = "$disp[$b]"; #showan

}

$b = "ENDED";

for($b = $firstnum; $b<sizeof($disp); $b++){

    $c = "$disp[$b]"; #dreturn

    echo = "$a$b$c";
}

my current output with this code is . andranetanurann .. And I want beter result like showanENDEDdreturn

Thanks for your time and understanding..

Answer 1

You are overwriting your variables every time it loops so only the result of the last loop is stored in the variable.

This code should return the required output.

$text = "showandreturn";
$disp = str_split($text, 2);
$num = 3;
$a = '';
$c = '';
for($b = 0; $b<$num; $b++){
    $a .= $disp[$b];
}
$b = "ENDED";
for($bn = $num; $bn<sizeof($disp); $bn++){
    $c .= $disp[$bn];
}
echo $a.$b.$c;
