how do I remove some numbers after the comma in PHP

This would be a solution

You use the round function that in the first parameter receives the number and in the second it receives the optional number of decimal digits to round with the default being 0

$valor = round(25.52382832732732, 2);
echo $valor;

font

One of the ways to do this is with number_format , from this momentum:

number_format($valor, 2);
