php - How to repeat a string while using a floating point number as multiplier -


i had repeat string n-times match length of string. problem multiplier floating point number , str_repeat accepts integer.

to more precisely had string of lowercase , uppercase letters of alphabet (strlen: 52) , had match length of string containing numbers 0-9 (strlen: 10) against it.

since did research before , not find answer looking going share function q&a-style.

to multiply string n-times floating point number multiplier need basic maths. here came with:

function str_repeat_float($str, $m){     $f = floor($m);     $d = $m - $f;     $l = strlen($str);     $p = floor($d * $l);     $r_str = str_repeat($str, $f);     $s_str = substr($str, 0, $p);     return $r_str.$s_str; } echo str_repeat_float('1234567890', 5.2); // 1234567890123456789012345678901234567890123456789012
