php can run like java perl python. Today I discovered that if I had known this earlier, maybe I would not have learned java and python

I learned java back then just to put a program on the server. After running and running, it turns out that php can also be used.

php -h

1. Use the php command line to execute the php script, such as /usr/bin/php test.php

Abbreviationphp test.php

test.php

<?php
for($i=0;$i<10;$i++){
 echo $i;
 echo &#39;\n&#39;;
}
?>

2. Write #!/usr/ on the first line at the beginning of the script bin/php, and then you can set the script to be executable chmod a

Execute for an hour and see if php will hang. I hope that a command line can run forever

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

##3. External incoming parameters

#!/usr/bin/php
<?php
for($i=0;$i<360;$i++){
 echo $i;
 sleep(10);
 echo " java-er.com \n";
}
?>
