Discussing all the files included in the PHP package is beyond the scope of this chapter. However, you should take a close look at the following files

Make sure that you can compile a working PHP environment by yourself! We won't go into this issue here, however, as you should already have this most basic ability when studying this chapter.

This is available since PHP 4.3.0 for compatibility with the deprecated dbm extension only and should be avoided. However you may use this where files were created in this format. That happens when configure could not find any external library.

There are many languages in which all characters can be expressed by single byte. Multi byte character codes are used to express many characters for many languages. mbstring is developed to handle Japanese characters. However, many mbstring functions are able to handle character encoding other than Japanese.

15 An average of 75 per cent among men, as compared to 65 among women. However, in the least developed countries, these differences are much wider. World Bank, Inequalities in Knowledge of HIV AIDS Prevention An Overview of Socio Economic and Gender Differentials in Developing Countries, 2001.

These remedies are provided for in paragraphs 2 and 3 of the Basic Principles the more detailed provisions only relate to remedies in relation to gross violations of human rights law rather than to any violation of human rights law however, they clearly offer useful guidance.

15 See however J. Mathis, WTO Core Principles and Prohibition Obligations Relating To Private Practices, National Competition Laws and Implications for a Competition Policy Framework (consultant report UNCTAD DITC CLP 2003 2) for the limits of the obligations upon WTO member States under this article and under the analogous GATT art. II.4

Beginning with PHP 4.3, bits and channels are present for other image types, too. However, the presence of these values can be a bit confusing. As an example, GIF always uses 3 channels per pixel, but the number of bits per pixel cannot be calculated for an animated GIF with a global color table.

A boolean. If TRUE piggyback is enabled for searches If FALSE piggyback is disabled. By default piggyback is enabled. Enabling piggyback is more efficient and usually saves a network round trip for first time fetches of records. However, a few Z39.50 targets doesn't support piggyback or they ignore element set names. For those, piggyback should be disabled.

GECOS is an obsolete term that refers to the finger information field on a Honeywell batch processing system. The field, however, lives on, and its contents have been formalized by POSIX. The field contains a comma separated list containing the user's full name, office phone, office number, and home phone number. On most systems, only the user's full name is available.

6 Regarding some of these issues, the coordinator prepared a considerable amount of text in the course of her mandate as Special Rapporteur on terrorism and human rights however, for reasons already stated in her reports, in the end she either did not include it or included it in very reduced form. Some of it could now usefully contribute to the drafting of the Sub Commission guidelines.

Because the effects may vary depending on the ODBC driver, use of this function in scripts to be made publicly available is strongly discouraged. Also, some ODBC options are not available to this function because they must be set before the connection is established or the query is prepared. However, if on a particular job it can make PHP work so your boss doesn't tell you to use a commercial product, that's all that really matters.

The function parses the XML document in str and returns a tree PHP objects as the parsed document. This function is isolated from the other functions, which means you cannot access the tree with any of the other functions. Modifying it, for example by adding nodes, makes no sense since there is currently no way to dump it as an XML file. However this function may be valuable if you want to read a file and investigate the content.

In the same way as there are no hard rules about how you organise the directory structure of a hard disk, a directory server manager can set up any structure that is meaningful for the purpose. However, there are some conventions that are used. The message is that you can not write code to access a directory server unless you know something about its structure, any more than you can use a database without some knowledge of what is available.

The default is to build PHP as a CGI program. This creates a commandline interpreter, which can be used for CGI processing, or for non web related PHP scripting. If you are running a web server PHP has module support for, you should generally go for that solution for performance reasons. However, the CGI version enables Apache users to run different PHP enabled pages under different user ids. Please make sure you read through the Security chapter if you are going to run PHP as a CGI.
