parallel processing - Parallelism in php -



parallel processing - Parallelism in php -

i want optimize part of code improve performance.since application create utilize of commandline tool , think improve performance execute lines of code in parallel rather executing code sequentially

<?php $value = exec("command goes here"); //this takes time /* instructions here don't depend on $value */ /* instructions here don't depend on $value */ $result = $value*2 ; //this dumb illustration ?>

i want execute codes don't depend on value @ same time $value whole script execute faster rather waiting exec() complete

unfortunately php despond in parallelism, concurrent,... programming. , never know why php dosen't back upwards these of import things , when php want back upwards these !!.

but may want utilize fork in php (if know problems , troubles in fork )
