Question

I have a file contain text

$field = array(
"fullname" => array("length"=5,"mandat"=>True),
"bithday" => array("length"=>10,"mandat"=>True)
"job" => array("length"=>3,"mandat"=>True),
"desc" => array("length"=>8,"mandat"=>false)
);
How can I get the array some thing like this:
$output = array(
//ABBCDE1990-12-10JOBALPHABET
0=>array(
"fullname" => "ABBCDE"
"bithday" => 1990-12-10
"job" => "JOB"
"desc"=> "ALPHABET"
)
//abbcde1990-12-10jobalphabet

function toOutput($str,$filed){
$per_line = 27;//len of abbcde1990-12-10jobalphabet
$pos = 0;
while ($pos<strlen($str)){
$pos += 27;
//
}
}

Answer 1

$field = array(
"fullname" => array("length"=>6,"mandat"=>True),
"bithday" => array("length"=>10,"mandat"=>True),
"job" => array("length"=>3,"mandat"=>True),
"desc" => array("length"=>8,"mandat"=>false)
);
$string = 'ABBCDE1990-12-10JOBALPHABETabbcde1990-12-10jobalphabet';
$result = array();
$countString = strlen($string)/27;
$oldPos = 0;
for($i=0;$i<$countString;$i++) {
foreach($field as $k=>$v) {
$result[$i][$k] = substr($string,$oldPos,$v['length']);
$oldPos += $v['length'];
}
}
print_r($result);
You can see it up and running here: http://codepad.org/CEQNIPCg (version 0.3)
Based on that you can create a function so you can pass to it all $string that you have
