I have a column in the database with the name of codigo , in which the formatting looks like this:
18000001
Where 18 means the year we are and 1 is the code for each result. Knowing that this code can be greater than 1 I type 18000011 and so on, I need to remove only the final value before it reaches zero,
1800044 - Preciso pegar só o 44
1800444 - Preciso pegar o 444
1804444 - Preciso pegar o 4444
You can do it this way:
$codigo = "1804444";
echo intval(substr($codigo, -5));
The substr function removes the 18 from the string and then this string is converted to integer returning in the case of the above example 4444.
You can do it this way
$codigo = "";
$cod = 4444;
if($cod != ""){
$anoAgora = substr(date("Y"),2,2);
$ano = substr($cod,0,2);
$num = substr($cod,2,5);
$numInt = intval($num);
if($anoAgora != $ano){
$codigo = $anoAgora . "00001";
}else{
$numInt += 1;
$strZeros ='';
//obter o número de digitos que tem a variável
$num1 = strlen($numInt);
//obter número de digitos(zeros) que faltam adicionar
$num3 = ((5 - $num1));
//criar a sequência de zeros em falta
for($i=0;$i<$num3;$i++){
$strZeros .='0';
}
$seqNum = $strZeros;
$codigo = $ano . $seqNum . $numInt;
}
}else{
$anoAgora = date("Y");
$codigo = substr($anoAgora,2,2) . "00001";
}
