PHP output a isosceles triangle method _php

The example in this paper describes a isosceles triangle method for PHP output. Share to everyone for your reference. The implementation method is as follows:

function Isosceles ($line, $sing) {  $tab = ' = ';    for ($i =1; $i < $line +1; $i + +) {    $blank = Print_blank ($i, $line, $tab);    $code = Print_code ($i, $sing);    Echo $blank. $code. $blank. "
";  }} function Print_blank ($num, $line, $tab) {  $blank = ';  for ($i = $num; $i < $line; $i + +) {    $blank. = $tab  ;}  return $blank;} function Print_code ($num, $sing) {  $code = ';  for ($i =0; $i < (($num-1) +1); $i + +) {    $code. = $sing;  }  return $code;} $line = 5; $sing = "*"; Isosceles ($line, $sing);

The results of the operation are as follows:

I hope this article is helpful to everyone's PHP programming.
