Install zend debugger for php 5.4.x on Mac OSX 10.9 64bit

After updating to OSX10.9, the default php shipped with OSX is updated to 5.4. Zend.com doesn't publicly provide a zend debugger for php5.4. The files used in this article are shipped with zend server. Here is the steps to install zend debugger for php5.4 on Mac OSX 10.9 64bit.

Step 1. Download ZendDebugger.so (download link) from https://github.com/mkb2000/zend_debugger.

Step 2. Put ZendDebugger.so to somewhere like /Library/WebServer/Documents/zend_debugger.

Step 3. Modify php.ini. The default configuration file used by Mac OS is at /private/etc/php.ini. Admin permission is required to modify this file. So go to /Applications/Utilities and open Terminal. Enter sudo nano /private/etc/php.ini. Jump to the end of this file and add 

[zend_debugger]
zend_extension="/the/path/to/the/folder/you/made/in/step2/ZendDebugger.so"
zend_debugger.allow_hosts=127.0.0.1, localhost
zend_debugger.expose_remotely=always

Control+x to save this file. You'd better comment out Xdebug if it is enabled. (There is also a full version of debug configure available at https://github.com/mkb2000/zend_debugger/blob/master/debugger.ini which is shipped with zend server.)

Step 4. Download dummy.php from https://github.com/mkb2000/zend_debugger/blob/master/dummy.php. Put it in your web server root document fold. By default, it is /Library/WebServer/Documents.

Step 5. Restart apache. In Terminal, enter sudo apachectl restart.


Step 6. Choose to use zend debugger in zend studio or eclipse.

yahoo stock data url

Historical quotes can be requested for any period in the past. To request historical quote an URL in the following format is used:

http://ichart.finance.yahoo.com/table.csv?s=MSFT&a=02&b=13&c=2001&g=d&ignore=.csv

The following lists the parameters of this URL

Parameter	Description
s=MSFT	Symbol for quote requested
a=02	Start month of quote requested (Zero based). 00-January, 01-February, 02-March, etc
b=13	Start day of quote requested
c=2001	Start year of quote requested
g=d	Frequency of quote requested. Value d here stands for "Daily"

An example of the returned data is as follows:

Date,Open,High,Low,Close,Volume,Adj Close
2012-05-03,31.88,31.90,31.61,31.76,31501300,31.76

Here's a neat way to download stock data from Yahoo, perhaps into a spreadsheet (so you can play with the data):

http://finance.yahoo.com/d/quotes.csv?s= a BUNCH of STOCK SYMBOLS separated by "+" &f=a bunch of special tags

for example: http://finance.yahoo.com/d/quotes.csv?s=XOM+BBDb.TO+JNJ+MSFT&f=snd1l1yr

where some special tags are:
