You could use what sep16 on php net recommends    lt  php  parse str implode   amp    array slice  argv  1      GET      gt    It behaves exactly like you d expect with cgi-php     php -f myfile php type daily a 1 b   2 b   3   will set   GET  type   to  daily     GET  a   to  1  and   GET  b   to array  2    3

There are four main alternatives  Both have their quirks  but Method 4 has many advantages from my view     script is a shell script starting by    usr bin php  Method 1   argv   script hello wo8844rld     argv 0     quot script quot    argv 1     quot hello quot    argv 2     quot wo8844rld quot      Using  argv  the parameter order is critical   Method 2  getopt     script -p7 -e3    getopt  quot p   quot    quot p quot      quot 7 quot   getopt  quot e   quot    quot e quot      quot 3 quot   It s hard to use in conjunction of  argv  because      The parsing of options will end at the first non-option found  anything that follows is discarded      Only 26 parameters as the alphabet   Method 3  Bash Global variable P9  quot xptdr quot    script    getenv  quot P9 quot      quot xptdr quot       SERVER  quot P9 quot      quot xptdr quot   Those variables can be used by other programs running in the same shell  They are blown when the shell is closed  but not when the PHP program is terminated  We can set them permanent in file    bashrc   Method 4  STDIN pipe and stream get contents   Some piping examples   Feed a string    script  lt  lt  lt   quot hello wo8844rld quot     stream get contents STDIN     quot hello wo8844rld quot    Feed a string using bash echo  echo  quot hello wo8844rld quot      script    explode  quot   quot  stream get contents STDIN         Feed a file content    script  lt    folder Special params txt    explode  quot  n quot  stream get contents STDIN         Feed an array of values    script  lt  lt  lt     quot array entry quot   quot lol quot       var dump  json decode trim stream get contents STDIN         Feed JSON content from a file  echo params json     script    json decode stream get contents STDIN         It might work similarly to fread   or fgets    by reading the STDIN   Bash-Scripting Guide

Parameters send by index like other applications  php myfile php type daily  And then you can get them like this   lt  php     if  count  argv     0           exit       foreach   argv as  arg          echo  arg    gt

You can use the following code to both work with the command line and a web browser  Put this code above your PHP code  It creates a   GET variable for each command line parameter  In your code you only need to check for   GET variables then  not worrying about if the script is called from the web browser or command line  if isset  argv       foreach   argv as  arg             e explode  quot   quot   arg           if count  e   2                GET  e 0    e 1           else               GET  e 0   0

These lines will convert the arguments of a CLI call like php myfile php  quot type daily amp foo bar quot  into the well known   GET-array  if   empty  argv 1        parse str  argv 1     GET      Though it is rather messy to overwrite the global   GET-array  it converts all your scripts quickly to accept CLI arguments  See parse str for details

The  type daily argument  ending up in the   GET array  is only valid for web-accessed pages  You ll need to call it like php myfile php daily and retrieve that argument from the  argv array  which would be  argv 1   since  argv 0  would be myfile php   If the page is used as a webpage as well  there are two options you could consider  Either accessing it with a shell script and Wget  and call that from cron     bin sh wget http   location to myfile php type daily  Or check in the PHP file whether it s called from the command line or not  if  defined  STDIN         type    argv 1     else      type     GET  type        Note  You ll probably need want to check if  argv actually contains enough variables and such

lt  php     if  count  argv     0          exit       foreach   argv as  arg          echo  arg    gt   This code should not be used  First of all  the CLI is called like   usr bin php phpscript php  It will have one argv value which is the name of the script  array 2        0   gt     string 13   quot phpscript php quot     This one will always execute since it will have one or two arguments passed

Using getopt   function we can also read a parameter from the command line just  Pass a value with the php running command  php abc php --name xyz  File abc php  val   getopt null    quot name  quot     print r  val      Output    name    gt   xyz

Just pass it as normal parameters and access it in PHP using the  argv array   php myfile php daily   and in myfile php   type    argv 1

I strongly recommend the use of getopt  If you want help to print out for your options then take a look at GetOptionKit

Save this code in file myfile php and run as php myfile php type daily   lt  php  a    argv   b   array    if  count  a      1  exit  foreach   a as  key   gt   arg        if   key  gt  0            list  x  y    explode       arg            b   x      y              gt    If you add var dump  b   before the   gt  tag  you will see that the array  b contains type   gt  daily
