PHP command line to write an instance of a shell command

This article to share the content is about the PHP command line to write the shell command instance, the content is very detailed, the need for friends can refer to, hope can help you.

PHP can run like Java Perl Python, and today I find that if I knew this early, maybe I wouldn't learn Java and Python.

That year to learn Java but in order to a program placed on the server, keep running and running, the original PHP can also.

1. Execute PHP scripts using the PHP command line, such as/usr/bin/php test.php

Abbreviationphp test.php

test.php

<?phpfor ($i =0; $i <10; $i + +) {echo $i; echo ' \ n ';}? >

2. The first line of the script is written on the #!/usr/bin/php, then the script can be set to execute chmod a+x test.php, then the script can be executed directly from the command line, for example./test.php

#!/usr/bin/php<?phpfor ($i =0; $i <10; $i + +) {echo $i; echo "java-er.com \ n";}? >

Execute an hour to see if PHP will hang, I hope a command line can run to the everlasting

#!/usr/bin/php<?phpfor ($i =0; $i <360; $i + +) {echo $i; sleep; echo "java-er.com \ n";}? >

3. External incoming parameters

#!/usr/bin/php<?php Var_dump ($ARGC); Returns the total number of parameters Var_dump ($ARGV); Exit;? >./test.phpint (1) Array (1) {[0]=> string (Ten) "./test.php"}./test.php a Java Phpint (4) Array (4) {[0]=> string (10 "./test.php" [1]=> string (1) "A" [2]=> string (4) "Java" [3]=> string (3) "PHP"}
