recode_string

Name

recode_string — Recodes a string according to a recode request.

Synopsis

string recode_string([. . .], text); string . . . (optional): Recode request (expressed as char_set_from..char_set_to) string text: Text to be converted

Returns

Recoded string; FALSE if the recode request fails

Description

recode_string() converts a string from one character set to another according to the specified recode request . The recode request should consist of the name of the character set to convert from, followed by two periods and the name of the target character set; for example, to convert from EBCDIC to ASCII, the request is "EBCDIC..ASCII".

If the recode request cannot be handled by recode, the function returns FALSE .

PHP Version: 3.0.13+, 4.0RC1+

Example

Example 1120. Convert a base 64 string to EBCDIC

print recode ('/Base64..EBCDIC', 'SGVsbG8gV29ybGQhDQo=');

Example 1121. Find the diacriticals in a string

<?php
# The names of the winter months in the French Republican Calendar
$hiver = 'Nivse, Pluvise, Ventise';

# Convert from ASCII to ASCII without diacriticals
$recoded = recode_string ('us..flat', $hiver);

# Find the accented characters
for ($x=0; $x < strlen ($hiver); ++$x) {
   if ($hiver[$x] !== $recoded[$x]) {
      $diacriticals[] = $hiver[$x];
   }
}

if (FALSE === is_array ($diacriticals))
   die ("There were no diacritical marks in the string: '$hiver'");

# find the number of diacriticals
$count = count ($diacriticals);

# Convert the array to a comma-separated string
$diacriticals = implode (', ', $diacriticals);

echo "There are $count diacritical marks <i>($diacriticals)</i> in the string: '$hiver'";
?>

Output:
There are 3 diacritical marks (, , ) in the string: 'Nivse, Pluvise, Ventise'
