说明

string <span class="methodname">intl_error_name ( <span class="methodparam">int $error_code )

Return ICU error code name.

参数

error_code
ICU error code.

返回值

The returned string will be the same as the name of the error code constant.

范例

示例 #1 intl_error_name example

<?php
$coll     = collator_create( 'en_RU' );
$err_code = collator_get_error_code( $coll );

printf( "Symbolic name for %d is %s\n.", $err_code, intl_error_name( $err_code ) );
?>
