Install php 7.2 ssh2 in ubuntu 16x

recently i need to install ssh2 connection through my php code to connect remote server by sftp for file transfer. i’m using php 7.2 and face a “sigment fault” issue for normal installation. i solved this issue by install required demon. hope it may help someone who face same issue.

first you need to install/upgrade some basic program

apt-get install gcc make autoconf libc-dev pkg-config

then install base library

apt-get install libssh2-1-dev

now install required php modules

apt-get install php7.2-dev php-pear

now install ssh by pecl (the most important part of installation)

— pecl channel-update pecl.php.net
pear config-show
— pear config-set php_ini /etc/php/7.2/apache2/php.ini
— pear config-set temp_dir /etc/php/temp/pear
pecl install ssh2-1.1.2

ignore commented line OR use if you understand by yourself

now you need to enable ssh2 extension into your php cli installation

echo “extension=ssh2.so” > /etc/php/7.2/mods-available/ssh2.ini
ln -s /etc/php/7.2/mods-available/ssh2.ini /etc/php/7.2/cli/conf.d/30-ssh2.ini

please check you php installation/configuration path. set priority on your own. i set here 30 without proper understanding ­čśÇ

now another important part is your PHP code. when we use ssh2 in fopen wraper, in other version of ssh2 connection we need to open a connection and we can use resource id. but with the above change you must use user, password, port i.e. full access information every time we need to connect to server. here is my sample code –

$fh = @fopen(‘ssh2.sftp://’ . $this->user.’:’.$this->pass.’@’.$this->ip.’:’.(intval($this->port)>0?intval($this->port):22) . $pRemoteLocation, $pMode);

all other code like directory creation or any other command execution may be same as before.

changing zf2 core 2.4.13 Zend/Stdlib/ArrayObject.php

class : Zend\Stdlib\ArrayObject
function: unserialize($data)
php version: 7.3

previous (original) code

/**
* Unserialize an ArrayObject
*

case ‘flag’:
$this->setFlags($v);
break;

break;
case ‘iteratorClass’:
$this->setIteratorClass($v);
break;
case ‘protectedProperties’:
continue;

}
}
}

new code

$this->protectedProperties = array_keys(get_object_vars($this));

$this->setFlags($ar[‘flag’]);

break;
case ‘storage’:
$this->exchangeArray($v);
break;
case ‘iteratorClass’:
$this->setIteratorClass($v);
break;
case ‘protectedProperties’:
/**
* in php 7.3 it shows
* Warning: “continue” targeting switch is equivalent to “break”. Did you mean to use “continue 2”? in /…location of zf2 ………../Zend/Stdlib/ArrayObject.php on line 426
*/
#continue;
$need2continue=true;
break;
default:
$this->__set($k, $v);
}
if(true==$need2continue) continue;
}

going to change ZF2.4.9 core

I decided to change ZF 2.4.9 core. I know its a wired decision. But I don’t have any choice, cause they didn’t provide any release for PHP 7x. But the change will noted in this site by adding post for future.

Today I’m changing –

class: Zend\Validator\EmailAddress
function: idnToAscii($email) and
function: idnToUtf8($email)

Previous (original) code –

protected function idnToAscii($email)
{
if (extension_loaded(‘intl’)) {
return (idn_to_ascii($email) ?: $email);
}
return $email;
}

protected function idnToUtf8($email)
{
if (extension_loaded(‘intl’)) {
return idn_to_utf8($email);
}
return $email;
}

New Code

protected function idnToAscii($email)
{
if (extension_loaded(‘intl’)) {
return (idn_to_ascii($email, IDNA_DEFAULT, INTL_IDNA_VARIANT_UTS46) ?: $email);
}
return $email;
}

protected function idnToUtf8($email)
{
if (extension_loaded(‘intl’)) {
return idn_to_utf8($email, IDNA_DEFAULT, INTL_IDNA_VARIANT_UTS46);
}
return $email;
}

I took this decision for –

https://bugs.php.net/bug.php?id=75609 and
https://wiki.php.net/rfc/deprecate-and-remove-intl_idna_variant_2003
