功能拆分PHP无法使用给定的模式

I need to split this (PHP)

$var = XXXXXX31,72YYYYYY32,73DDDDDD33,74

to result

[0] => XXXXXX31,72
[1] => YYYYYY32,73
[2] => DDDDDD33,74

I am using function preg_split

with pattern ('/(?=[a-z]+)(?<=[0-9])/i',$var);

But it is returning

[0] => 31,72
[1] => XXXXXX32,73
[2] => YYYYYY33,74
[3] => DDDDDD

I've made assumptions about how you actually want to split the string. If this isn't what you want, you'll have to tell us what behavior you actually intended.

$input = "TIPO DISCRIMINAÇÃO PRAZO VALOR1.923,11VENCIMENTO BASICORENDIMENTOS230,77ANUENIO - ART.244, LEI 8112/900013.596,99GRATIFICACAO NATALINA93,65FGR-FUNC GRATIFICADA L 8216/91155,46GRAT.DESEMP.FUNCAO-GADF LD.13368,58AUXILIO-TRANSPORTE955,20GDPGPE - LEI 11.784/2008 AT238,80GDPGPE - LEI 11.784/2008 AT0011.568,44ADIANT.GRATIF.NATALINA/ATIVO123,45";
$matches = [];

preg_match_all("/.*?[\\d.]+,\\d{2}/", $input, $matches);

print_r($matches[0]);

// Output:
// Array

// )

here you go Try this + there is a typo in your input, i think you meant to have 6 X's instead of 5.

$var = 'XXXXX31,77YYYYYY32,77DDDDDD33,77';
$array = explode('77',$var);
$array = array_filter($array); // remove empty elements

for ($i = 0; $i < count($array); $i++)
{
    $array[$i] .= '77';
}
echo "<pre>";
print_r($array);
echo "</pre>";

outputs

Array
(
    [0] => XXXXX31,77
    [1] => YYYYYY32,77
    [2] => DDDDDD33,77
)
