ldap_err2str — Convert LDAP error number into string error message

### 说明

ldap_err2str ( int `$errno` ) : string

Returns the string error message explaining the error number `errno`. While LDAP errno numbers are standardized, different libraries return different or even localized textual error messages. Never check for a specific error message text, but always use an error number to check.

### 参数

`errno`

  The error number.

### 返回值

Returns the error message, as a string.

### 范例

Example #1 Enumerating all LDAP error messages

    <?php
      for ($i=0; $i<100; $i++) {
        printf("Error $i: %s<br />\n", ldap_err2str($i));
      }
    ?>
