$string = "Hello World Again".
echo strrchr($string , ' '); // Gets ' Again'

Now I want to get "Hello World" from the $string [The substring before the last occurrence of a space ' ' ]. How do I get it??



This is kind of a cheap way to do it, but you could split, pop, and then join to get it done:

$string = 'Hello World Again';
$string = explode(' ', $string);
$string = implode(' ', $string);

Here's what worked best for me when trying to script this (in case anyone else comes across this like I did):

$ pecl -d php_suffix=5.6 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.0 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.1 install <package>
$ pecl uninstall -r <package>

The -d php_suffix=<version> piece allows you to set config values at run time vs pre-setting them with pecl config-set. The uninstall -r bit does not actually uninstall it (from the docs):

vagrant@homestead:~$ pecl help uninstall
pecl uninstall [options] [channel/]<package> ...
Uninstalls one or more PEAR packages.  More than one package may be
specified at once.  Prefix with channel name to uninstall from a
channel not in your default channel (

  -r, --register-only
        do not remove files, only register the packages as not installed

The uninstall line is necessary otherwise installing it will remove any previously installed version, even if it was for a different PHP version (ex: Installing an extension for PHP 7.0 would remove the 5.6 version if the package was still registered as installed).

First thing on my mind:

if ($string[0] == '/') $string = substr($string,1);
if ($string[strlen($string)-1] == '/') $string = substr($string,0,strlen($string)-1);

You could do this:

$string = 'The quick brown fox jumped over the lazy dog';
$substring = substr($string, 0, strpos($string, ' '));

But I like this better:

list($firstWord) = explode(' ', $string);

Never used any of those, but they look interesting..

Take a look at Gearman as well.. more overhead in systems like these but you get other cool stuff :) Guess it depends on your needs ..
