是否可以使用PHP从A到ZZ获得范围？
a b c ... aa ... zx zy zz
对我而言，这不起作用：
range('A', 'ZZ');
适用于PHPExcel，当它将 BE 作为最高字段时，我会遍历所有列。在这种情况下，我只得到A，B：
range ('A', 'BE')

利用PHP增加字符“perl-style”的能力
$letters = array();
$letter = 'A';
while ($letter !== 'AAA') {
$letters[] = $letter++;
}
但你也可以使用简单的整数值，并利用PHPExcel的内置PHPExcel_Cell :: stringFromColumnIndex（）方法
修改
从PHP 5.5开始，您还可以使用Generators来避免在内存中实际构建数组
function excelColumnRange($lower, $upper) {
++$upper;
for ($i = $lower; $i !== $upper; ++$i) {
yield $i;
}
}
foreach (excelColumnRange('A', 'ZZ') as $value) {
echo $value, PHP_EOL;
}

试试这个 - （测试工作正常）
function createColumnsArray($end_column, $first_letters = '')
{
$columns = array();
$length = strlen($end_column);
$letters = range('A', 'Z');
// Iterate over 26 letters.
foreach ($letters as $letter) {
// Paste the $first_letters before the next.
$column = $first_letters . $letter;
// Add the column to the final array.
$columns[] = $column;
// If it was the end column that was added, return the columns.
if ($column == $end_column)
return $columns;
}
// Add the column children.
foreach ($columns as $column) {
// Don't itterate if the $end_column was already set in a previous itteration.
// Stop iterating if you've reached the maximum character length.
if (!in_array($end_column, $columns) && strlen($column) < $length) {
$new_columns = createColumnsArray($end_column, $column);
// Merge the new columns which were created with the final columns array.
$columns = array_merge($columns, $new_columns);
}
}
return $columns;
}
echo "<pre>";
print_r( createColumnsArray('BZ'));

for ($i = 'A'; $i !== 'AC'; $i++){

你可以组合两个foreach循环来生成类似的东西。
// Single letters
foreach(range('A', 'Z') as $letter) {
echo $letter;
}
// AA-ZZ combinations
foreach(range('A', 'Z') as $letter1) {
foreach(range('A', 'Z') as $letter2) {
echo $letter1 . $letter2;
}
}

使用内置range：
添加了对字符序列和递减数组的支持 4.1.0。字符序列值限制为长度为1。如果输入的长度大于1，则仅使用第一个字符。
然而，从本质上讲，你在这里做的是从使用26位a到z的数字系统中的1开始向上计数。因此，您可以通过计算，转换为基数26（使用数字0至9和a至p）快速入侵解决方案，然后“翻译”数字范围为a到z。

更好的选择（工作得很好）
for ($i = 'a'; $i < 'zz'; $i++)
echo $i."<br>";
答案 6 :(得分：1)
您可以编写自己的函数来执行此操作，因为似乎php中的range（）函数不支持此功能。这应该是一项简单的工作，因为您可以将范围函数嵌套在另一个循环中。像这样：
foreach(range('a', 'z') as $outer) {
foreach(range('a', 'z') as $inner) {
print($outer.$inner);
}
}

我使用alpha2num（）将alpha转换为数字，然后在循环中使用它。有了这个，我可以使用开始和结束的任何值来获得范围。
// to convert alpha to number
function alpha2num($a) {
$l = strlen($a);
$n = 0;
for($i = 0; $i < $l; $i++)
$n = $n*26 + ord($a[$i]) - 0x40;
return $n-1;
}
// to convert number back to alpha
function num2alpha($n)
{
for($r = ""; $n >= 0; $n = intval($n / 26) - 1)
$r = chr($n%26 + 0x41) . $r;
return $r;
}
function get_range($start_column, $end_column)
{
$s = alpha2num($start_column); // get start number
$e = alpha2num($end_column); // get end num
$columns = array();
// loop from start to end and change back the number to alpha to be stored in array
for($i=$s; $i<=$e; $i++)
$columns[] = num2alpha($i);
return $columns;
}
// usage
$columns = get_range('Z', 'BA'));

这是一个简化的解决方案，您可以在其中定义要生成的行数和列数。这样，您将分配较少的内存。
// Get cell names for excel
function generate_excel_cell_names($row_cnt, $col_cnt){
$excel_cells = [];
// Note: Row and col indexes are starting from 1
for ($excel_row=1; $excel_row <= $row_cnt; $excel_row++) {
$excel_col = 'A';
for ($col_index = 1; $col_index <= $col_cnt; $col_index++)
{
$excel_cells[$excel_row][$col_index] = $excel_col.$excel_row;
$excel_col++;
}
}
return $excel_cells;
}
