Easily extract data from string formatted a specific way - php

Question

What is an easy way to take a string that is formatted this way:
c:7|bn:99
and be able to use that string easily? So if I wanted to get the number that is behind the c:, How could I get that easily. Same, thing with the number behind bn:?

Answer 1

You could use preg_match() function or you could use explode() function twice (first with | delimiter and second with : delimiter).
Example #1:
<?php
if( preg_match( '/^c:(\d+)\|bn:(\d+)$/', $sString, $aMatches ) )
{
print_r( $aMatches );
}
?>
Example #2:
<?php
$aPairs = explode('|', $sString ); // you have two elements in $aPairs
foreach( $aParis as $sPair )
{
print_r( explode(':', $sPair ) );
}
?>

Answer 2

$arr = array();
$str = "c:7|bn:99";
$tmp1 = explode('|', $str);
foreach($tmp1 as $val)
{
$tmp2 = explode(':', $val);
$arr[$tmp2[0]] = $tmp2[1];
}
//print ur array
print_r($arr);
//accessing specifc value
echo $arr['c']." ".$arr['bn'];

Answer 3

Try this:
$string = 'c:7|bn:99';
preg_match('/\Ac:([0-9]+)\|bn:([0-9]+)\z/', $string, $matches);
var_dump($matches);

Answer 4

If c & bn are not dynamic:
var_dump(sscanf("c:7|bn:99","c:%d|bn:%d"));
array(2) {
[0]=>
int(7)
[1]=>
int(99)
}
