Req #70087 [NEW]: Better string interpolation

From: mario dot dweller at seznam dot cz Operating system: PHP version: 7.0.0beta1 Package: PHP Language Specification Bug Type: Feature/Change Request Bug description:Better string interpolation Description: ------------ There is a support for variable interpolation in strings like $string = "$a/$b $c"; or $string = "{$a}/{$b} {$c}"; But it is not usable for functions. $string = "Length: {strlen($a)}"; I guess that's why many programmers prefer using sprintf instead because it is more readable than concatenation using dots. I personally use sprintf almost everywhere because the code looks more consistent then. Since there are many cool new features in PHP7, why not to add this basic one? I guess it would need a special syntax because of BC, or not? But there are currently two ways to achieve the same thing: $string = "Hello {$a}"; $string = "Hello ${a}"; The second one looks unnaturally, most prefer the first way. For example it could be forbidden in favor of this: $string = "Length is ${strlen(a)}"; -- Edit bug report at https://bugs.php.net/bug.php?id=70087&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70087&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70087&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70087&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70087&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70087&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70087&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70087&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70087&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70087&r=support Expected behavior: https://bugs.php.net/fix.php?id=70087&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70087&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70087&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70087&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70087&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70087&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70087&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70087&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70087&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70087&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70087&r=mysqlcfg
