vsprintf ou sprintf avec des arguments nommés, ou simple modèle d'analyse en PHP

Autant que je sache printf/sprintf n'accepte pas assoc tableaux.

Toutefois, il est possible de faire printf('%1$d %1$d', 1);

Mieux que rien 😉

C'est à partir de php.net

function vnsprintf( $format, array $data)
{
    preg_match_all( '/(?<!%) % ( (?: [[:alpha:]_-][[:alnum:]_-]* | ([-+])? [0-9]+ (?(2) (?:\.[0-9]+)? | \.[0-9]+ ) ) ) $ [-+]? \'? .? -? [0-9]* (\.[0-9]+)? \w/x', $format, $match, PREG_SET_ORDER | PREG_OFFSET_CAPTURE);
    $offset = 0;
    $keys = array_keys($data);
    foreach( $match as &$value )
    {
        if ( ( $key = array_search( $value[1][0], $keys, TRUE) ) !== FALSE || ( is_numeric( $value[1][0] ) && ( $key = array_search( (int)$value[1][0], $keys, TRUE) ) !== FALSE) )
        {
            $len = strlen( $value[1][0]);
            $format = substr_replace( $format, 1 + $key, $offset + $value[1][1], $len);
            $offset -= $len - strlen( 1 + $key);
        }
    }
    return vsprintf( $format, $data);
}

Exemple:

$example = array(
    0 => 'first',
    'second' => 'second',
    'third',
    4.2 => 'fourth',
    'fifth',
    -6.7 => 'sixth',
    'seventh',
    'eighth',
    '9' => 'ninth',
    'tenth' => 'tenth',
    '-11.3' => 'eleventh',
    'twelfth'
);

echo vnsprintf( '%1$s %2$s %3$s %4$s %5$s %6$s %7$s %8$s %9$s %10$s %11$s %12$s<br />', $example); //acts like vsprintf
echo vnsprintf( '%+0$s %second$s %+1$s %+4$s %+5$s %-6.5$s %+6$s %+7$s %+9$s %tenth$s %-11.3$s %+10$s<br />', $example);

Exemple 2:

$examples = array(
    2.8=>'positiveFloat',    //key = 2 , 1st value
    -3=>'negativeInteger',    //key = -3 , 2nd value
    'my_name'=>'someString'    //key = my_name , 3rd value
);

echo vsprintf( "%%my_name$s = '%my_name$s'\n", $examples);    //[unsupported]
echo vnsprintf( "%%my_name$s = '%my_name$s'\n", $examples);    //output : "someString"

echo vsprintf( "%%2.5$s = '%2.5$s'\n", $examples);        //[unsupported]
echo vnsprintf( "%%2.5$s = '%2.5$s'\n", $examples);        //output : "positiveFloat"

echo vsprintf( "%%+2.5$s = '%+2.5$s'\n", $examples);        //[unsupported]
echo vnsprintf( "%%+2.5$s = '%+2.5$s'\n", $examples);        //output : "positiveFloat"

echo vsprintf( "%%-3.2$s = '%-3.2$s'\n", $examples);        //[unsupported]
echo vnsprintf( "%%-3.2$s = '%-3.2$s'\n", $examples);        //output : "negativeInteger"

echo vsprintf( "%%2$s = '%2$s'\n", $examples);            //output : "negativeInteger"
echo vnsprintf( "%%2$s = '%2$s'\n", $examples);            //output : [= vsprintf]

echo vsprintf( "%%+2$s = '%+2$s'\n", $examples);        //[unsupported]
echo vnsprintf( "%%+2$s = '%+2$s'\n", $examples);        //output : "positiveFloat"

echo vsprintf( "%%-3$s = '%-3$s'\n", $examples);        //[unsupported]
echo vnsprintf( "%%-3$s = '%-3$s'\n", $examples);        //output : "negativeInteger"

C'est simple et ne pas utiliser les regexp

function format_string($string, array $args = array()) {
  //Transform arguments before inserting them.
  foreach ($args as $key => $value) {
    switch ($key[0]) {
      case '@':
        //Escaped only.
        $args[$key] = check_plain($value);
        break;

      case '%':
      default:
        //Escaped and placeholder.
        $args[$key] = drupal_placeholder($value);
        break;

      case '!':
        //Pass-through.
    }
  }
  return strtr($string, $args);
}

function drupal_placeholder($text) {
  return '<em class="placeholder">' . check_plain($text) . '</em>';
}

Exemple:

$unformatted = 'Hello, @name';
$formatted = format_string($unformatted, array('@name' => 'John'));

C'est ce que j'utilise:

$arr = ['a' => 'happy','b' => 'funny'];

$templ = "I m a [a] and [b] person";

$r = array_walk($arr,function($i,$k) use(&$templ){
    $templ = str_replace("[$k]",$i,$templ);
} );

var_dump($templ);

Assez Simple

<?php
   //sprintf with place holders
   function printPh($string,Array $params){
      $tok = strtok($string,':');
      $msg = ''; 
      while($tok !== false){
         $msg .= array_key_exists($tok,$params) ? $params[$tok] : $tok;
         $tok = strtok(':');
      }

      return $msg;
   }

   echo spfwph('<p>:ph1: :ph2:</p>',['ph1'=>'placerholder 1','ph2'=>'placeholder 2']);
